Description

Technical Field

[0001] INFORMATION The present invention relates to a communication interface, and more particularly to an optical communication interface, for use in protocols such as High-Definition Multimedia Interface (HDMI). Background Art

[0002] A variety of communication interfaces have been developed and used in the field of high-speed communication. For example, High Definition Multimedia Interface (HDMI), Universal Serial Bus (USB), Display Port (DP), Digital Visual Interface (DVI), and Video Graphics Array (VGA) interfaces are relatively common in the market and continue to develop. For example, High Definition Multimedia Interface (HDMI) is an audio / video interface used to transmit compressed or uncompressed audio / video data from a source device (such as a Blu-ray Disc (BD) player) to a receiving device (such as a television (TV)). As multimedia applications become more prevalent, the use of HDMI is also increasing. The HDMI communication system can transmit signals in the communication interface by electronic means, optical means, or hybrid means (e.g., electronic and optical combinations). For example, in electronic implementations, wires can be set in the cable; in optical implementations, optical fibers can be set in the cable; in hybrid implementations, wires and optical fibers can be set in the cable.

[0177] P1 Fiber DETAILED DESCRIPTION

[0178] Embodiments of the present invention relate to a communication using a protocol, such as a High Definition Multimedia Interface (HDMI). This technology includes systems, methods, apparatus, and / or communication interfaces that are applied to communication between HDMI devices to improve various aspects of the overall communication (e.g., power, form factor, convenience, etc.). The apparatus, system, and method of the present invention may provide a number of technical effects and advantages. Although the present description focuses on the communication interface of HDMI, embodiments of the present invention may also be equally applicable to a Universal Serial Bus (USB), DisplayPort (DP), Digital Video Interface (DVI), Video Graphics Array (VGA), or other types of communication interfaces.

[0179] In particular, according to certain embodiments, an HDMI communication system may provide a data communication interface between a first HDMI device (e.g., a laptop) and a second HDMI device (e.g., a display). Typically, the HDMI communication system may include a first HDMI coupling module and a second HDMI coupling module. The first HDMI coupling module includes a first device connector for coupling to the first HDMI device; the second HDMI coupling module includes a second device connector for coupling to the second HDMI device. The HDMI communication system may also include one or more optical fibers coupled between the first and second HDMI modules, configured to provide multiple data transmission channels between the first and second HDMI coupling modules. As described throughout the present invention, the optical communication system or optical coupling module may be fully optical (i.e., only optical fiber is used for the connection between the two devices) or hybrid (i.e., the connection between the two devices is a combination of optical fiber and electrical wires).

[0180] According to one embodiment of the present invention, an HDMI system has a bidirectional communication function. Some conventional HDMI communication systems require one end of an HDMI cable to be connected to a source device, and the other end of the HDMI cable to be connected to a receiving device. For these conventional HDMI cables, the cable circuit at the source end is only designed for data transmission function, and the cable circuit at the receiving end is only designed for data reception function. Therefore, if the source end of the cable is connected to the receiving device, and / or the receiving end of the cable is connected to the source device, the communication system cannot achieve correct operation. By designing a dual-mode optical transmitter-receiver and related circuits at the source end and the receiving end of the HDMI communication system, it is possible to operate normally regardless of which end of the HDMI cable is plugged into the receiving device or the source device. In other words, both ends of the HDMI cable can be used for data transmission and reception. Therefore, the present invention provides a communication system with a bidirectional function, which makes it easier to operate, the connection of the devices at both ends is more flexible, and there is the possibility of adding other functions.

[0181] Another embodiment of the present invention is an optical HDMI communication system having a detachable connector connected to a fiber optic cable. For example, the HDMI communication system may include a first HDMI coupling module and a second HDMI coupling module. Each coupling module may include a device connector for coupling an HDMI device, and a cable connector for coupling a fiber optic cable. At least one cable connector is detachable relative to the fiber optic cable. For example, in some embodiments, the first cable connector and the second cable connector can be detached from the fiber optic cable. This architecture is suitable for different applications and allows interchange of fiber optic cables with different lengths, thereby facilitating design flexibility and / or system customization. For example, some applications require longer distance transmission, that is, require fiber optic cables with larger size or function. By creating an HDMI communication system with detachable components, a plug-and-play design can be achieved, thereby providing a variety of technical advantages and overall design flexibility. As another embodiment, the detachable connector allows the coupling module to remain plugged into the corresponding source / receiver device, so that the source / receiver device can be easily moved without the need to carry additional fiber optic cables.

[0182] Another embodiment of the present invention is an HDMI communication system with a power saving mode function. The HDMI communication system with a power saving mode function can advantageously reduce the degradation of system functions, reduce power consumption and operating costs for connecting HDMI devices, and improve HDMI system efficiency.

[0183] In some embodiments, the power saving mode function can be achieved by setting a switch (e.g., a touch sensor) on at least one of the first HDMI coupling module or the second HDMI coupling module. For example, a touch sensor is provided for switching on and off data transmission on the optical fiber cable between the first HDMI coupling module and the second coupling module. In some embodiments, the touch sensor is disposed on the circuit housing of a given HDMI coupling module. A system with such a touch sensor can provide a user with the option of manually switching the power saving mode. In addition, the HDMI communication system can switch on and / or off data transmission without actually unplugging the cable, thereby reducing wear on the cable.

[0184] In other power saving mode implementations of the present invention, when there is no data transmission between the first HDMI coupling module and the second HDMI coupling module, one or more channels of the plurality of channels in the optical fiber cable operate in the power saving mode.

[0185] In particular, in some embodiments, a power saving mode function may be provided at the transmitting end of the HDMI communication system. In one embodiment, a first HDMI coupling module (e.g., a transmitting module) may be connected to a plurality of data signal lines from a first HDMI device (e.g., a source side device), and when one or more of the plurality of data signal lines from the first HDMI device show no data transmission, the first HDMI coupling module generates a control signal to operate one or more of the plurality of channels in a power saving mode. In another embodiment, the first HDMI coupling module may be used to monitor the data transmission status of the plurality of data signal lines from the first HDMI device. When one or more of the plurality of data signal lines presents no data transmission within a time limit, one or more channels corresponding to the one or more data signal lines may be switched to operate in a power saving mode.

[0186] Furthermore, in some embodiments, a power saving mode function may be provided at the receiving end of the HDMI communication system. For example, the second HDMI coupling module (e.g., receiving module) may include a power saving circuit configured to monitor a specific channel of the plurality of channels between the first HDMI coupling module and the second HDMI coupling module. The specific channel operates in a traffic detection mode. When the specific channel detects no data transmission traffic, the remaining channels of the plurality of channels between the first HDMI coupling module and the second HDMI coupling module operate in a power saving mode. When the specific channel detects data transmission traffic, the remaining channels of the plurality of channels between the first HDMI coupling module and the second HDMI coupling module are activated to operate in a data transmission mode.

[0187] Furthermore, the effects and advantages of the present technology can be understood by disclosing a system and method for power-on sequence of an all-optical HDMI communication system. The system and method help coordinate and integrate confirmation signals during the operation of the all-optical HDMI communication system. By removing or reducing the use of electronic signals between the first end and the second end of the HDMI cable, the advantages of optical transmission can be better understood (for example, thin cables, no additional power is required, and can still be used for long-distance data communication, and maintain stable transmission effects).

[0188] Embodiments of the present invention are further directed to an optical communication interface having other functions, such as light-emitting functions, power transmission over optical fiber, and vibration sensing capabilities. For example, a cable having a light-emitting function can emit light according to the transmission state. In some embodiments, a vibration sensor can monitor the vibration level of the cable, and the cable can emit light according to the vibration level. Further, another embodiment of the present invention allows power to be transmitted in the optical fiber cable to provide power to a receiver of the interface, such as an audio-visual (A / V) or sideband receiver.

[0189] The apparatus, system and method of the present invention can provide a number of technical effects and advantages. For example, a cable with a light-emitting function according to an embodiment of the present invention can provide a user with a visual indication of the state of data transmission in the cable. For example, an HDMI cable with a light-emitting function can allow a user to quickly know the resolution of the image transmission on the cable, such as during the playback of audio / video (A / V) media.

[0190] In addition, the devices, systems and methods of the present invention improve upon techniques for providing power to cable receivers. For example, light transmitted over an optical fiber can be converted into an electronic signal suitable for providing power to a cable receiver, such as an audio / video (A / V) or sideband receiver. In certain embodiments, this technique can reduce the need for an additional power source, such as that provided by a receiving device (e.g., a television or monitor).

[0191] Embodiments of the present invention will be discussed in more detail with reference to the accompanying drawings. Figure 1 A bidirectional HDMI communication system 100 according to an embodiment of the present invention is shown. The HDMI communication system 100 is generally configured as an optical communication interface between a first HDMI device 102 and a second HDMI device 104. The first HDMI device 102 and the second HDMI device 104 may include various devices, such as but not limited to source devices (e.g., Blu-ray disc players, laptops, personal computers, game consoles, etc.) and / or sink devices (e.g., televisions, monitors, etc.).

[0192] like Figure 1 As shown, the HDMI communication system 100 may include a first HDMI coupling module 110, a second HDMI coupling module 120, and an optical fiber cable 130. The first HDMI coupling module 110 may include a first connector 112 for coupling the first HDMI device 102, and a first optical transmitter-receiver 114 configured as a receiving end (e.g., a receiver) or a source end (e.g., a transmitter). The second HDMI coupling module 120 may include a second connector 122 for coupling the second HDMI device 104, and a second optical transmitter-receiver 124 configured as a receiving end or a source transmitter-receiver. When configured as a transmitter, the optical transmitter-receiver receives one or more electronic signals from the HDMI device at the source end, and converts the one or more electronic signals into one or more optical signals (e.g., by using a driver circuit to drive one or more light sources, such as light emitting diodes or lasers). When configured as a receiver, the optical transmitter-receiver receives one or more optical signals (e.g., by using a photodiode), and converts the one or more optical signals into one or more electronic signals, and provides them to the receiving device (e.g., by using a transimpedance amplifier to convert the photocurrent into a voltage).

[0193] The optical fiber cable 130 may be coupled between the first HDMI coupling module 110 and the second HDMI coupling module 120, and may include one or more optical fibers. The optical fiber cable 130 may be further configured to provide data transmission and reception of multiple channels between the first HDMI coupling module 110 and the second HDMI coupling module 120. For example, the HDMI cable may include four data channels and one or more sideband channels for transmitting information, such as power information, audio return channel (ARC / eARC), serial clock information (SCL), serial data information (SDA), consumer electronics control signal (CEC), hot plug detection signal (HPD), etc. Each channel may use separate optical fibers, or may use a single optical fiber with wavelength division multiplexing / demultiplexing, time division multiplexing / demultiplexing, and / or code division multiplexing / demultiplexing. The first HDMI coupling module 110 and the second HDMI coupling module 120 are disposed at opposite ends of the optical fiber cable as connector devices.

[0194] In some embodiments, the HDMI communication system 100 may be a hybrid system having one or more wires 150 coupled between the first HDMI coupling module 110 and the second HDMI coupling module 120. For example, a high-speed bidirectional data transmission channel 135 (such as Figure 2 As shown) can be achieved using optical means (for example: an optical transmitter and receiver are coupled to an optical fiber), and low-speed data (for example: CEC, universal (Utility), hot plug detection signal (HPD), display data channel (DDC)), etc.) can be achieved using wires (for example: an electronic transmitter and receiver are coupled to wires, such as: copper wires).

[0195] According to an embodiment of the present invention, the HDMI communication system 100 can be configured for bidirectional functionality. Therefore, if the first HDMI device 102 is configured for operation of a source device (e.g., a television, a laptop, a game console, etc.), and the second HDMI device 104 is configured for operation of a sink device (e.g., a monitor or other display device), the HDMI communication system 100 will provide the same functionality regardless of whether the first connector 112 is physically coupled to the first HDMI device 102 and the second connector 122 is physically coupled to the second HDMI device 104, or the first connector is physically coupled to the second HDMI device 104 and the second connector 122 is physically coupled to the first HDMI device 102. Because the source and sink (e.g., the first HDMI coupling module 110 and the second HDMI coupling module 120) in the HDMI communication system 100 have a first optical transmitter-receiver 114, a second optical transmitter-receiver 124, and related circuits (e.g., Figure 2For an HDMI cable having the HDMI communication system 100, the communication function is not affected no matter which end is connected to the source device or the receiving device.

[0196] Both ends of the HDMI communication system 100 (e.g., the first HDMI coupling module 110 and the second HDMI coupling module 120) are configured for data transmission and reception. In particular, the first optical transmitter-receiver 114 of the first HDMI coupling module 110 can transmit optical audio / video signals to the second optical transmitter-receiver 124 of the second HDMI coupling module 120 via the optical fiber cable 130, and can also receive optical audio / video signals from the second optical transmitter-receiver 124. Similarly, the second optical transmitter-receiver 124 can transmit optical audio / video signals to the first optical transmitter-receiver 114 via the optical fiber cable 130, and can receive optical audio / video signals from the first optical transmitter-receiver 114.

[0197] In certain embodiments, Figure 5 As shown, at least one of the first HDMI coupling module 110 or the second HDMI coupling module 120 is detachable relative to the optical fiber cable 130. In a further embodiment, as Figure 6 As shown, the first HDMI coupling module 110 or the second HDMI coupling module 120 may include a switch (eg, a touch sensor) configured to switch on and off data transmission on the optical fiber cable.

[0198] Figure 2-Figure 4 According to another embodiment of the present invention, the bidirectional HDMI communication system may include Figure 1 The HDMI communication system shown.

[0199] like Figure 2 As shown, the first HDMI coupling module 110 and the second HDMI coupling module 120 have similar components. For example, the first HDMI coupling module 110 includes a first optical transmitter-receiver 114 and related circuits, and the second HDMI coupling module 120 includes a second optical transmitter-receiver 124 and related circuits. The first optical transmitter-receiver 114 is configured to transmit to and receive from the first HDMI device (e.g. Figure 1 The second optical transmitter and receiver 124 is configured to transmit and receive video signals 115, audio signals 116, and control / status signals 117 to and from the second HDMI device (e.g., the first HDMI device 102). Figure 1 The video signal 125, audio signal 126 and control / status signal 127 of the second HDMI device 104 are displayed.

[0200] like Figure 2As shown, the first HDMI coupling module 110 may include a first non-transitory computer-readable storage medium 118 configured to store extended display identification data (EDID) indicating the first HDMI device (eg Figure 1 In some embodiments, when the first HDMI device (e.g. Figure 1 When the first HDMI device (e.g., the first HDMI device) is configured as a receiving device, the EDID information stored in the first non-transitory computer-readable storage medium 118 is important. The second HDMI coupling module 120 may include a second non-transitory computer-readable storage medium 128 configured to store extended display identification data (EDID), indicating that the second HDMI device (e.g., the first HDMI device) is configured as a receiving device. Figure 1 In some instances, when the second HDMI device (e.g. Figure 1 When a second HDMI device) is used as a receiving device, the EDID information stored in the second non-transitory computer readable storage medium 128 is important.

[0201] In some embodiments, the first HDMI coupling module 110 and the second HDMI coupling module may include respective CEC control circuits 119 and 129, respectively, for transmitting and coordinating consumer electronics control (CEC) functions between the first HDMI device 102 and the second HDMI device 104. In some embodiments, the first HDMI coupling module 110 and the second HDMI coupling module 120 may include respective HDMI Ethernet and Audio Return Channel (HEAC) circuits 131 and 132, respectively, for providing a connection device (e.g. Figure 1 The HEAC circuits 131 and 132 may also use a hot plug (HPD) line for signal transmission for signal transmission. In a further embodiment, the first HDMI coupling module 110 and the second HDMI coupling module 120 may respectively include respective HPD detection circuits 133 and 134 for communication confirmation of coupling to the HDMI device (e.g. Figure 1 The power signal is received by one or more pins on the connectors (eg, the first connector 112 and / or the second connector 122) of the first HDMI device 102 and the second HDMI device 104.

[0202] like Figure 2As shown, a plurality of channels may be provided on the optical fiber cable 130 for transmitting the aforementioned functions described between the first HDMI coupling module 110 and the second HDMI coupling module 120. For example, the communication channels in the optical fiber cable 130 between the first HDMI coupling module 110 and the second HDMI coupling module 120 may include a plurality of bidirectional data transmission channels 135 configured to transmit and receive data between the first HDMI coupling module 110 and the second HDMI coupling module 120, and one or more clock channels 136. In some embodiments, the bidirectional data transmission channels 135 and / or the one or more clock channels 136 may be configured to transmit data formatted using the Transition-Minimized Differential Signaling (TMDS) protocol. Additional channels for communication between the first HDMI coupling module 110 and the second HDMI coupling module 120 may include, but are not limited to: a display data channel (DDC) line for communication between the first non-transitory computer-readable storage medium 118 and the second non-transitory computer-readable storage medium 128; a CEC line 138 for communication between the first CEC control circuit 119 and the second CEC control circuit 129; a utility line 139 for communication between the first HEAC circuit 131 and the second HEAC circuit 132; and a HPD line for communication between the first HEAC circuit 131 and the first detection circuit 133 and between the second HEAC circuit 132 and the second detection circuit 134. In some embodiments, the HDMI coupling modules 110 and 120 may be hybrid, with video and audio data transmitted via one or more optical fibers and other control data (e.g., CEC, DDC, utility, and / or HPD, etc.) transmitted via one or more wires. In some embodiments, the HDMI coupling modules 110 and 120 may be all-optical, with video and audio data, as well as control data, being transmitted via one or more optical fibers.

[0203] like Figure 3-Figure 4 As shown, it is further discussed how the optical fiber cable 130 includes an HDMI channel for bidirectional communication between the first HDMI coupling module 110 and the second HDMI coupling module 120.

[0204] Specifically, Figure 3The optical fiber cable 130 may include a plurality of bidirectional data transmission channels 151-154 configured to bidirectionally transmit and receive data between the first optical transmitter-receiver 114 of the first HDMI coupling module 110 and the second optical transmitter-receiver 124 of the second HDMI coupling module 120. In some embodiments, the bidirectional data transmission channels 151-154 may include at least three optical channels configured to transmit data formatted using the transition minimized differential signaling (TMDS) protocol. In some embodiments, Figure 3 The first bidirectional data transmission channel 151, the second bidirectional data transmission channel 152, and the third bidirectional data transmission channel 153 may correspond to Figure 2 The data channel 135 located on the optical fiber cable 130, Figure 3 The fourth bidirectional data transmission channel 154 may correspond to Figure 2 The clock channel 136.

[0205] exist Figure 4 In the embodiment, the optical fiber cable 130 may include a first group of optical fibers configured for unidirectional data transmission of data communication channels 161-164 from the first optical transmitter-receiver 114 of the first HDMI coupling module 110 to the second optical transmitter-receiver 124 of the second HDMI coupling module 120. The optical fiber cable 130 also includes a second group of optical fibers configured for unidirectional data transmission of data communication channels 165-168 from the second optical transmitter-receiver 124 of the second HDMI coupling module 120 to the first optical transmitter-receiver 114 of the first HDMI coupling module. In some embodiments, the data transmission channels 161-164 on the first group of optical fibers may include at least three optical channels for transmitting data, and one or more clock channels using the transition minimized differential signaling (TMDS) protocol. Similarly, the data transmission channels 165-168 on the second group of optical fibers may include at least three optical channels for transmitting data, and one or more clock channels using the transition minimized differential signaling (TMDS) protocol.

[0206] Figure 5 The detachable HDMI communication system 200 is a block diagram of an embodiment of the present invention. The detachable HDMI communication system 200 is generally used as a first and a second HDMI device (eg Figure 1 The detachable HDMI communication system 200 may include a first HDMI coupling module 210, a second HDMI coupling module 220, and cables 230a / 230b. Figure 5 The first HDMI coupling module 210 may include Figure 1-Figure 2Some or all of the features and functions of the first HDMI coupling module 110 are shown, or may include different features and functions. Figure 5 The second HDMI coupling module 220 may include Figure 1-Figure 2 Some or all of the features and functions of the second HDMI coupling module 120 are shown, or may include different features and functions.

The detachable HDMI communication system 200 may include Figure 3-Figure 4 Some or all of the data transmission channel configurations shown may alternatively include different channel structures and functions.

[0207] In certain embodiments, Figure 5 The first HDMI coupling module 210 may include a first device connector 212 for coupling a first HDMI device (eg, Figure 1 The first HDMI device 102), and the first cable connector 214 are used to couple the optical fiber cables 230a / 230b.

[0208] like Figure 5 As shown, the detachable HDMI communication system 200 can be configured with at least one of the first cable connector 214 or the second cable connector 224, which is detachable to the optical fiber cable 230a / 230b. In some embodiments, the first cable connector 214 can make the first HDMI coupling module 210 detachable relative to the optical fiber cable 230a / 230b, and the second cable connector 224 can make the second HDMI coupling module 220 detachable relative to the optical fiber cable 230a / 230b. For example, the first cable connector 214 and the first end connector 216 of the optical fiber cable 230a / 230b have a corresponding pluggable form of joint. For example, the first cable connector 214 can provide a socket connector suitable for matching positioning relative to the first end connector 216 of the optical fiber cable 230a / 230b. Similarly, the second cable connector 224 can provide a socket connector suitable for matching positioning relative to the second end connector 226 of the optical fiber cable 230a / 230b. Other types of connection methods, including but not limited to magnetic connection, may also be applied to the present invention.

[0209] In some embodiments, the detachable HDMI communication system 200 may include different fiber optic cables for different applications. For example, the detachable HDMI communication system 200 may include a first fiber optic cable 230a having a first length for use with a first optical data, wherein the first fiber optic cable 230a is coupled to a first cable connector 214 of the first HDMI coupling module 210, and is coupled to a second cable connector 224 of the second HDMI coupling module 220. The detachable HDMI communication system 220 may also include a second fiber optic cable 230b having a second length for use with a second optical data, wherein the second length is different from the first length of the first fiber optic cable 230a. The second fiber optic cable 230b may be coupled to the first cable connector 214 of the first HDMI coupling module 210, and is coupled to the second cable connector 224 of the second HDMI coupling module 220.

In particular, through the optical fiber cable 230a / 230b, the first optical transmitter and receiver in the first HDMI coupling module 210 can be used to transmit optical audio / video signals to the second optical transmitter and receiver in the second HDMI coupling module 220, and receive optical audio / video signals from the second optical transmitter and receiver in the second HDMI coupling module.

The touch sensor 340 can include, for example, a soft button, a hard button, a switch, a sensor for gesture recognition, and / or other switch interfaces for a user interface. The touch sensor 340 can be used to switch on or off the data transmission of multiple channels of the optical fiber cable 330 between the first HDMI coupling module 310 and the second HDMI coupling module 320. For example, the touch sensor 340 can be electrically coupled to the power management circuit of the first HDMI coupling module 310 to control the first HDMI coupling module 310. When the data transmission in the HDMI communication system 300 is activated by the touch sensor 340, the data channel in the optical fiber cable 330 is set in a data transmission mode. When the data transmission in the HDMI communication system 300 is switched off by the touch sensor 340, the data channel in the optical fiber cable 330 is set in a non-activation mode or a sleep mode without data transmission.

[0214] Figure 7-Figure 8 The present invention is an embodiment of a power-on system and method for an HDMI communication system according to an embodiment of the present invention. Figure 7-Figure 8 The illustrated embodiments may be incorporated into the aforementioned HDMI communication systems 100 , 200 , 300 , or may be additional or alternative HDMI communication systems thereto.

[0215] like Figure 7 As shown, the HDMI communication system 400 is generally used as a first and a second HDMI device ( Figure 1 The HDMI communication system 400 may include a first HDMI coupling module 410, a second HDMI coupling module 420, and an optical fiber cable 430. The first HDMI coupling module 410 may include a first device connector 412 for coupling the first HDMI device (e.g., Figure 1HDMI source transmitter and receiver (e.g. Figure 1-Figure 2 The first optical transmitter and receiver 114 of the embodiment is configured to transmit data related to the first HDMI device, and the receiving side circuit 415 is configured to receive a power start signal from the first HDMI device and generate a first optical signal 413, which is transmitted from the first HDMI coupling module 410 to the second HDMI coupling module 420. The second HDMI coupling module 420 may include a second device connector 422 for coupling the second HDMI device ( Figure 1 The second HDMI device 104), the HDMI receiving end transmitting receiver (eg Figure 1-Figure 2 The second optical transmitter and receiver 124 is configured to transmit data related to the second HDMI device, and the receiving side circuit 425 is configured to receive the first optical signal 413 from the source side circuit 415 and generate a second optical signal 423, which is transmitted from the second HDMI coupling module 420 to the first HDMI coupling module 410. The optical fiber cable 430 is coupled between the first HDMI coupling module 410 and the second HDMI coupling module 420, and provides data transmission of multiple channels between the first HDMI coupling module 410 and the second HDMI coupling module 420 according to the second optical signal 423 received by the first HDMI coupling module 410.

[0216] like Figure 7 As shown, the first optical signal 413 may represent a power-on signal 416 (e.g., a positive voltage signal (e.g., a +5V signal)) from a first HDMI device (e.g., the first HDMI device 102), and the power-on signal 416 may be detected from one or more pins of the first device connector 412. The power-on signal 416 may be received from a source-side circuit 415 (e.g., a source-side protocol integrated circuit (IC)), and the source-side circuit 415 may convert the power-on signal 416 from an electronic signal to an optical signal 413 and transmit it on the optical fiber cable 430. In some embodiments, the source-side circuit 415 of the first HDMI coupling module 410 is configured to wait for a first stabilization time to pass between receiving the power-on signal 416 from the first HDMI device and transmitting the first optical signal 413 from the first HDMI coupling module to the second HDMI coupling module 420.

[0217] The receiving side circuit 425 (e.g., receiving end protocol IC) is configured to receive the first optical signal 413 and convert it into an electronic signal, which is transmitted to the second HDMI device connected to the second device connector 422. The electronic signal from the receiving side circuit 425 can be used as a power start signal for the second HDMI device (e.g., a +5V signal for USB). In some embodiments, the second HDMI coupling module 420 can include a diode (e.g., one or more Schottky diodes 429) to prevent the power start signal provided to the second HDMI device from having reverse power flow back to the receiving side circuit 425. The receiving side circuit 425 in the second HDMI coupling module 420 can receive a hot plug signal 426 from the second HDMI device and convert the HPD signal 426 into a second optical signal 423. The second optical signal 423 represents a hot plug detect (HPD) signal 426 received from the second HDMI device, and the hot plug detect (HPD) signal 426 is detected from one or more pins of the second device connector 422. The source-side circuit 415 in the first HDMI coupling module 410 is used to receive the second optical signal 423 and start a data transmission circuit (e.g., a wake-up signal) to transfer data between the first HDMI coupling module 410 and the second HDMI coupling module 420. In some embodiments, the source-side circuit 415 of the first HDMI coupling module 410 is configured to wait for a second stabilization time after receiving the second optical signal 423 and transferring data from the HDMI source-end transmitter-receiver in the first HDMI coupling module 410 to the HDMI sink-end transmitter-receiver in the second HDMI coupling module 420.

In some embodiments, the method 500 may optionally include a step of waiting for a first stabilization time, the first stabilization time being the time elapsed between receiving the power-on signal from the first HDMI device in step 505 and transmitting the first optical signal from the first HDMI coupling module to the second HDMI coupling module in step 510.

[0221] In step 515, method 500 may include providing, at a second HDMI coupling module (eg, Figure 7 The receiving side circuit (e.g., the second HDMI coupling module 420) in Figure 7 The receiving side circuit 425) receives the first optical signal (eg Figure 7 The first optical signal 413 of FIG. 1 is converted into the first optical signal (eg, the first optical signal 413) by using a receiving side circuit (eg, a receiving side circuit 425). Figure 7 The first optical signal 413) becomes a power start signal for the second HDMI device.

[0222] In step 520, method 500 may include, via a receiving side circuit (eg, Figure 7 The receiving side circuit 425 receives a hot plug detection (HPD) signal (eg, Figure 7 HPD signal), and using the receiving side circuit (e.g. Figure 7The receiving side circuit 425) converts the HPD signal (eg Figure 7 HPD signal) becomes a second optical signal (eg Figure 7 of the second optical signal 423).

[0223] In step 525, method 500 may include providing, via a second HDMI coupling module (eg, Figure 7 The second HDMI coupling module 420) transmits the second optical signal (eg Figure 7 The second optical signal 423) is sent to the first HDMI coupling module (eg Figure 7 The first HDMI coupling module 410) is used to respond to the received first optical signal (eg Figure 7 of the first optical signal 413).

[0224] In step 530, method 500 may include providing, via a first HDMI coupling module (eg, Figure 7 The HDMI source end transmitter and receiver in the first HDMI coupling module 410 receives the second optical signal (eg Figure 7 The second optical signal 423) and the first HDMI coupling module (eg Figure 7 The first HDMI coupling module 410) responds to the received second optical signal (eg Figure 7 The second optical signal 423) starts the data transmission circuit for the first HDMI coupling module (eg Figure 7 The first HDMI coupling module 410) and the second HDMI coupling module (eg Figure 7 data transmission between the second HDMI coupling module 420).

[0225] In step 535, method 500 may include providing, via a first HDMI coupling module (eg, Figure 7 ), transmits data from the first HDMI device to the second HDMI coupling module (e.g., Figure 7 In some embodiments, the method 500 may optionally include a step of waiting for a second stable time, the second stable time being the time elapsed between receiving the second optical signal in step 530 and transmitting data between the HDMI source transceiver in the first HDMI coupling module and the HDMI sink transceiver in the second HDMI coupling module in step 535.

[0226] Fig. 9 FIG. 6 is a block diagram of a power saving HDMI communication system 600 according to an embodiment of the present invention. The HDMI communication system 600 is configured as a first HDMI device and a second HDMI device (eg, Figure 1The power saving HDMI communication system 600 may include a first HDMI coupling module 610, a second HDMI coupling module 620, and a cable 630. The first HDMI coupling module 610 may include a first device connector 612 coupled to the first HDMI device (e.g., Figure 1 The first HDMI device 102) and the data transmitter 614 are used to transmit the data received from the first HDMI device. In some embodiments, the data transmitter 614 can be transmitted through a first optical transmitter receiver (e.g. Figure 1-Figure 2 The second HDMI coupling module 620 may include a second device connector 622 coupled to a second HDMI device (eg, Figure 1 The second HDMI device 104) and the data receiver 624 are used to receive the data designated to be received by the second HDMI device. In some embodiments, the data receiver 624 can be transmitted through a second optical transmitter receiver (e.g. Figure 1-Figure 2 The optical fiber cable 630 coupled between the first HDMI coupling module 610 and the second HDMI coupling module 620 may include Figure 1-Figure 2 The optical fiber cable 130 and the electrical wire 150 shown may have some or all of the features and functions and may be configured to provide multiple channels of data transmission between the first HDMI coupling module 610 and the second HDMI coupling module 620 .

[0227] like Fig. 9 As shown, when there is no data transmission between the first HDMI coupling module 610 and the second HDMI coupling module 620, one or more of the multiple channels provided by the optical fiber cable 630 can operate in a power saving mode. In one embodiment, the first HDMI coupling module 610 may include a power saving circuit 616 coupled to the data transmitter 614, configured to provide a power saving function on the transmitter side of the HDMI communication system 600. In one embodiment, the power saving circuit 616 may include a signal detector configured to receive multiple data signal lines from the first HDMI device. When there is no data on one or more of the multiple data signal lines from the first HDMI device, the power saving circuit 616 may be configured to generate a control signal to operate one or more of the multiple channels on the optical fiber cable 630 in a power saving mode. In another embodiment, the first HDMI coupling module 610 may be configured to monitor whether there is data on the multiple data signal lines from the first HDMI device. When no data is present on one or more of the data signal lines within a time limit, the related one or more data signal lines in one or more channels provided by the optical fiber cable 630 may be controlled by the power saving circuit 616 to operate in a power saving mode.

[0228] In some embodiments, the power saving circuit 616 can be coupled to a microcontroller in an HDMI coupling module (e.g., the HDMI coupling module 610). When one or more of the data signal lines present no data within a time limit, the power saving circuit 616 can send a control signal to the microcontroller to enter a power saving mode. When one or more of the data signal lines present data within a time limit, the power saving circuit 616 can send a control signal to the microcontroller to leave the power saving mode.

[0229] In some embodiments, the HDMI coupling module may be configured to operate in a mode of sending data through a primary group data channel. For example, in a fixed rate link (FRL) mode, if the FRL link rate is lower than a limit (e.g., 6 Gbps), the HDMI coupling module may send data through three channels. If the FRL link rate is lower than a limit, the HDMI coupling module may send data through four channels. When the FRL link rate is lower than a limit, the power saving circuit 616 may be configured to control one of the four channels to enter a power saving mode.

[0230] In one embodiment, the second HDMI coupling module 620 may include a power saving circuit 626 coupled to the data receiver 624, configured to provide a power saving function on the receiver side of the HDMI communication system 600. In one implementation, the power saving circuit 626 in the second HDMI coupling module 620 may be configured to monitor a specific channel of a plurality of channels on the optical fiber cable 630 between the first HDMI coupling module 610 and the second HDMI coupling module 620, the function of the specific channel being set for data detection. When no data traffic is detected on the specific channel, the remaining channels of the plurality of channels provided on the optical fiber cable 630 between the first HDMI coupling module 610 and the second HDMI coupling module 620 may be set to operate in a power saving mode. When data traffic is detected on the specific channel, all data channels provided on the optical fiber cable 630 are activated in an operating mode for data transmission.

[0231] Fig.10 According to an embodiment of the present invention, Fig. 9 600 is a block diagram of another embodiment of a power saving HDMI communication system. In particular, Fig.10 Show Fig. 9, different channels provided by the optical fiber cable 630 between the data transmitter 614 of the first HDMI coupling module 610 and the data receiver 624 of the second HDMI coupling module 620. In one embodiment, the optical fiber cable 630 may provide a plurality of data channels 631-634 and a plurality of utility channels 635. A specific channel (e.g., data channel 631) of the plurality of data channels 631-634 may be designated to be set to an operation mode for traffic detection. When no data traffic is detected on the specific channel 631, the remaining channels 632-634 of the plurality of channels 631-634 may be operated in a power saving mode. When no data traffic is detected on the specific channel 631, the specific channel 631 may remain activated to monitor data traffic. When data traffic is detected on the specific channel 631, all data channels 631-634 on the optical fiber cable 630 may be set in an operation mode for data transmission.

[0232] Fig.11 1 is an embodiment of an optical communication interface 1100. The optical communication interface 1100 may include a device that can be used to transmit and receive signals. For example, the optical communication interface 1100 may include a transmitter and a receiver 1102 and 1104 (for example, referring to Figure 1 The optical communication interface 1100 may further include a device that can be used to connect various devices. For example, the optical communication interface 1100 may include connectors 1150 and 1160 (for example, disposed at opposite ends of the optical communication interface). The optical communication interface 1100 may further include a device that can be used to transmit signals. For example, the optical communication interface 1100 may include a cable 1180. As further described herein, the cable may include one or more optical fibers, for example, including a first optical fiber (for example, reference Figure 1 In some embodiments, the cable may also include one or more wires (e.g., Figure 1 According to other embodiments of the present invention, the optical communication interface 1100 (eg, the cable 1180) may further include a light emitting element 1190 (eg, Fig.12 ). For example, the light emitting element 1190 can partially or completely surround the cable 1180 (eg, the first optical fiber). In certain embodiments, the cable 1180 can be a coiled cable or a non-coiled cable.

[0233] In various embodiments, the optical communication interface 1100 can be HDMI, USB, DVI, VGA, or other types of optical communication interfaces. In some embodiments, the connectors 1150 and 1160 can be coupled to various devices, such as a source device (e.g., a Blu-ray disc player, a notebook computer, a personal computer, a game console, etc.) and / or a receiving device (e.g., a television, a monitor, etc.).

[0234] The light (labeled LT) emitted by the light emitting element 1190 may correspond to data information. For example, the light LT emitted by the light emitting element 1190 may vary according to the data information communicated on the cable 1180. The data information may be, for example, one or more characteristics related to the first transceiver or the second transceiver.

[0235] For example, in some embodiments, the data information (e.g., one or more characteristics related to the first transceiver or the second transceiver) may be data transmission rate, clock rate, image resolution, power consumption, temperature, vibration level, content of the transmitted data, content related to the input data, content related to the first optical signal, or other types of data information processed by the transceivers 1102 and 1104.

[0236] For example, in some embodiments, the frequency of the light LT (e.g., the number of light pulses in a time period) can be changed according to the information of the data. For example, when transmitting data information of a first resolution (e.g., a lower resolution), the light LT can have a first frequency (e.g., 2 pulses per second), and when transmitting data information of a second resolution (e.g., a higher resolution), the light LT can have a second frequency (e.g., 4 pulses per second). Similarly, light LT of other frequencies can be generated to transmit various data information to the user.

[0237] In some embodiments, the color of the light LT emitted by the light emitting element 1190 can be changed according to the data information. For example, the light LT can emit a related color for temperature data information (e.g., the temperature of one or more components of the optical communication interface 1100, the ambient temperature, etc.). For example, when the temperature data information is a first temperature (e.g., 50°F), the light LT emits a first color (e.g., blue), and when the temperature data information is a second temperature (e.g., 90°F), the light LT emits a second color (e.g., red). Similarly, light LT of other colors can convey various data information to the user. This light information can be used to identify whether the system or optical communication interface is operating normally or may be overheated.

[0238] In some embodiments, the brightness (e.g., luminous intensity) of the light LT emitted by the light emitting element 1190 can be varied. For example, when the power consumption data information (e.g., charging rate or charging amount) is displayed at a first power consumption level (e.g., low power consumption level), the light LT can emit a first brightness (e.g., 10 lumens), and at a second power consumption level, the light LT can emit a second brightness (e.g., 20 lumens). Similarly, the light LT can emit other brightnesses to convey various data information to the user.

[0239] In some embodiments, the optical communication interface (e.g., optical control circuit) can be configured to partially control the light emitting element 1190 based on the comparison of the data information with the threshold value. For example, the amount of light LT emitted by the light emitting element 1190 can be varied based on the data information (e.g., one or more characteristics). For example, when a first type of media (e.g., an audio file) is transmitted, a corresponding first amount of light (e.g., a single light) can be emitted, while when a second type of media (e.g., an audio-video file) is transmitted, a corresponding second amount of light (e.g., two light) can be emitted. For example, the light emitting element 1190 can include multiple light sources (e.g., light emitting diodes (LEDs), optical fibers, etc.), which can be selectively activated to increase or decrease the amount of light LT emitted by the light emitting element 1190. Similarly, the light LT can emit other amounts of light to transmit various data information to the user.

[0240] In some embodiments, when the data information is at a first level (e.g., below a threshold), the light LT emitted by the light emitting element 1190 may be a first type of light (e.g., flickering, strobing, fading, swaying, etc.), and when the data information is above the threshold, the light LT emitted by the light emitting element 1190 may be a second type of light (e.g., constant). For example, power consumption, clock rate, resolution, vibration level, etc. may have various thresholds and corresponding light. Similarly, various data information (e.g., game-related information, audio media, AV media, etc.) may have corresponding types of light LT.

[0241] Fig.12 1 is a cross-sectional view of a cable 1180 according to an embodiment of the present invention. For example, the cable 1180 may be Fig.11 1 . As shown, the cable 1180 includes a light emitting element 1190 and a plurality of optical fibers F1, F2, F3, and F4. In various embodiments, the cable 1180 may include any number of optical fibers (e.g., a single optical fiber, two optical fibers, etc.). In certain embodiments, in addition to the optical fibers, the cable 1180 may include one or more electrical wires (e.g., copper wires). For example, the electrical wires may be used to transmit information that requires a low transmission rate, such as metadata associated with the source and / or receiving device. Further, as shown, the light emitting element 1190 may partially or completely surround the cable 1180, covering the optical fibers F1-F4.

[0242] Each optical fiber F1-F4 may be configured to transmit one or more optical signals. For example, in some embodiments, the optical signal may be generated by a transceiver (eg, 1102, 1104, etc.).

[0243] According to an embodiment of the present invention, the light emitting element 1190 may emit corresponding light LT according to the data information. For example, the data information may be transmitted via one or more optical fibers F1-F4. For example, in some embodiments, the data information (e.g., one or more characteristics related to the first transceiver or the second transceiver) may include data transmission rate, clock rate, image resolution, power consumption, temperature, vibration level, and / or content related to input data. In some embodiments, the data information (e.g., one or more characteristics) may include the vibration level transmitted from the vibration sensor as described herein.

[0244] The light emitting element 1190 may emit light in various forms. For example, in some embodiments, the light emitting element 1190 may include one or more light beams wrapped around the optical fibers F1-F4. In some embodiments, the light emitting element 1190 may include a light emitting portion (e.g., a light-transmitting portion) and a non-light emitting portion (e.g., a black-shielded portion). In some embodiments, the light emitting element may include a light emitting diode (LED), a laser diode, a light bulb, and / or other light emitting elements.

[0245] In some embodiments, the light LT emitted from the light emitting element 1190 may include various types of light (e.g., color, frequency, brightness, amount of light, etc.). For example, the type of light emitted by the light emitting element 1190 and / or the properties of the light may be controlled according to the data information on the optical fibers F1-F4.

[0246] Fig.13 The optical communication interface 1100 is an optical communication interface according to an embodiment of the present invention. The optical communication interface 1100 may include a device for converting, transmitting, and receiving signals. For example, as shown in the figure, the transmitter-receiver 1102 and 1104 are arranged at opposite ends of the cable 1180. The optical communication interface 1100 may further include a tool for connecting to various devices. For example, the connector 1150 / 1160 may be configured to connect the optical communication interface 1100 to various source ends and receiving ends as described herein. The optical communication interface may further include a device for emitting light LT. For example, the light emitting element 1190 may be configured to emit light LT based on data information (for example, based on at least a portion of the data information). As shown in the figure, the first transmitter-receiver 1102 may include a transmitter 1021, a receiver 1022, and an optical control circuit 1023. Similarly, the transmitter-receiver 1104 may include a transmitter 1041 and a receiver 1042.

[0247] Transmitter 1021 may be configured to transmit input data through connector 1150 to receiver 1042. For example, in some embodiments, data input to connector 1150 may include electronic signals, which may be converted into optical signals and transmitted through one or more optical fibers (e.g., F1, F2).

[0248] The receiver 1042 may be configured to receive optical signals on one or more optical fibers (eg, F1, F2) and convert the received optical signals into electronic signals. The converted electronic signals may be output to the connector 1160, such as to be provided to a receiving device.

[0249] The transmitter 1041 may be configured to transmit data input to the connector 1160 to the receiver 1022. For example, the data input to the connector 1160 may be an electronic signal that is converted into an optical signal and then transmitted through one or more optical fibers (F3, F4).

[0250] The receiver 1022 may be configured to receive optical signals on one or more optical fibers (eg, F3, F4) and convert the received optical signals into electronic signals. The converted electronic signals may be output to the connector 1150, such as to be provided to a source device.

[0251] The optical communication interface 1100 may further include a means for controlling the light emitting element 1190 to emit light LT. Fig.13 In the optical communication interface 1100 shown, the transmitter-receiver 1102 may further include a light control circuit 1023. The light control circuit 1023 may be configured to generate a light control signal C1 for controlling the light LT according to the data information processed by the transmitter 1021. For example, the input data provided to the connector 1150 may be converted from an electronic signal to an optical signal by the transmitter 1021, and data information corresponding to the input data may be provided to the light control circuit 1023. The light control circuit 1023 may control the light LT emitted by the light emitting element 1190 according to the data information.

[0252] For example, the data information may be data transmission rate (for example, the data transmission rate of data transmitted from transmitter 1021 and transmitted on optical fibers F1 and F2), clock rate (for example, the frequency of clock cycles), image resolution (for example, the number of pixels in the communication image), power consumption (for example, the power consumption of the receiving device, the source device, etc.), temperature (for example, operating temperature), vibration level (for example, information obtained by a vibration sensor as described herein), and / or the content of the transmitted data (for example, the type of transmitted data, such as audio, game, A / V media, etc.).

[0253] In some embodiments, the light control circuit 1023 can be configured to control the light emission mode of the light emitting element 1190, such as the light emission color, frequency, brightness, light type, light quantity and / or other properties of the light LT as described herein. For example, the light LT emitted by the light emitting element 1190 can be controlled by the light control circuit 1023 according to the data information of one or more signals transmitted on the optical fiber (e.g., F1-F4).

[0254] The light control circuit 1023 can be implemented by appropriate tools, such as an application specific integrated circuit (ASIC), a digital signal processor (DSP), a general purpose processor, a processor core, a microprocessor, a controller, a microcontroller, and an operatively connected processor or multiple processors. In some embodiments, the light control circuit 1023 may include one or more non-transitory computer readable storage media, such as a random access memory (RAM), a read-only memory (ROM), an electronically erasable and rewritable read-only memory (EEPROM), an erasable and rewritable read-only memory (EPROM), one or more memory devices, a flash memory device, etc., and combinations thereof.

[0255] In this method, the light LT emitted by the light emitting element 1190 can be controlled to provide visual information to the user. For example, the light LT emitted by the light emitting element 1190 can be controlled by the light control circuit 1023 to provide a visual indication of one or more attributes of the data information communicated on the cable 1180. This can allow the user to easily confirm the operating status of the source device, the receiving device, and / or the optical communication interface 1100.

[0256] Fig.14 1 is an optical communication interface 1100 according to an embodiment of the present invention. Fig.13 In the optical communication interface 1100 shown, the transmitter-receiver 1102 and the transmitter-receiver 1104 are disposed on opposite sides of the cable 1180. The connector 1150 / 1160 can be configured to connect the optical communication interface 1100 to various source ends and receiving ends as described herein. The light emitting element 1190 can be configured to emit light LT according to data information. As shown, the transmitter-receiver 1102 can include a transmitter 1021 and a receiver 1022. Similarly, the transmitter-receiver 1104 can include a transmitter 1041 and a receiver 1042. However, as Fig.14 As shown, the transmitter receiver 1104 includes a light control circuit 1043. The light control circuit 1043 can essentially operate as Fig.13 The light control circuit 1023 is shown.

[0257] For example, the transmitter 1021 may be configured to transmit input data provided to the receiver 1042 via the connector 1150. For example, the data input to the connector 1150 may include electronic signals that are converted into optical signals and then transmitted through one or more optical fibers (eg, F1, F2).

[0258] The receiver 1042 may be configured to receive optical signals transmitted on one or more optical fibers (eg, F1, F2) and convert the received optical signals into electronic signals, and then output the converted electronic signals to the connector 1160.

[0259] The transmitter 1041 may be configured to transmit data input to the connector 1160 to the receiver 1022. For example, the data input to the connector 1160 may be an electronic signal, which is converted into an optical signal and then transmitted through one or more optical fibers (eg, F3, F4).

[0260] The receiver 1022 may be configured to receive optical signals transmitted on one or more optical fibers ( F3 , F4 ) and convert the received optical signals into electronic signals. The converted electronic signals may be output to the controller 1150 .

[0261] The optical control circuit 1043 can be configured to generate an optical control signal C1 to control the light LT according to the data information processed by the receiver 1042. For example, the optical signal transmitted on the optical fibers F1 and F2 and received by the receiver 1042 can be converted into an electronic signal by the receiver 1042, and the data information related to the electronic signal is provided to the optical control circuit 1043.

[0262] For example, the data information may be a data transmission rate (e.g., the transmission rate at which data received by the receiver 1042 is transmitted on the optical fibers F1 and F2), a clock rate (e.g., the frequency of a clock cycle), an image resolution (e.g., the number of pixels in a communication image), power consumption (e.g., power consumption of a receiving device, a source device, etc.), a temperature (e.g., operating temperature), a vibration level (e.g., information obtained by a vibration sensor as described herein), and / or the content of the transmitted data (e.g., the type of transmitted data).

[0263] In some embodiments, the light control circuit 1043 may be configured to control the light emission mode of the light emitting element 1190, such as the light emission color, frequency, brightness, light type, light quantity, and / or other properties of the light LT as described herein. For example, the light control circuit 1043 may control the light LT emitted by the light emitting element 1190 according to data information of one or more signals transmitted on the optical fiber (e.g., F1-F4).

[0264] The light control circuit 1043 can be implemented by suitable tools, such as application specific integrated circuits (ASICs), digital signal processors (DSPs), general purpose processors, processor cores, microprocessors, controllers, microcontrollers, and operatively connected processors or multiple processors. In some embodiments, the light control circuit 1023 may include one or more non-transitory computer readable storage media, such as RAM, ROM, EEPROM, EPROM, one or more memory devices, flash memory devices, etc., and combinations thereof.

[0265] In this manner, the light LT emitted by the light emitting element 1190 can be controlled to provide visual information to the user. For example, the light LT emitted by the light emitting element 1190 can be controlled by the light control circuit 1023 to provide a visual indication of one or more attributes of the data information communicated on the cable 1180. This can allow the user to easily confirm the operating status of the source device, the receiving device, and / or the optical communication interface 1100.

[0266] Fig.15 The optical communication interface 1100 according to an embodiment of the present invention is shown. As shown, the optical communication interface 1100 may include transmitters and receivers 1102 and 1104, which are disposed at opposite ends of a cable 1180. Connectors 1150 / 1160 may be configured to connect the optical communication interface 1100 to various source ends and receiving ends as described herein. As shown, the transmitter and receiver 1102 may include a transmitter 1021 and a receiver 1022. Similarly, the transmitter and receiver 1104 may include a transmitter 1041 and a receiver 1042. The receiver 1042 may be configured to receive an optical signal transmitted on an optical fiber (e.g., F1, F2) and convert the received optical signal into an electronic signal. The converted electronic signal may be output to the connector 1160. The transmitter 1041 may be configured to transmit data input to the connector 1160 to the receiver 1022. For example, the data input to the connector 1160 may be an electronic signal, and converted into an optical signal, which is transmitted through one or more optical fibers (e.g., F3, F4).

[0267] According to another embodiment of the present invention, the optical communication interface 1100 may further include an optical fiber P1 for providing power to the receiver 1042 through the transmitter 1021. For example, the optical fiber P1 may be an optical fiber, and the optical signal transmitted by the transmitter 1021 is converted into an electronic signal that can be used to power the receiver 1042 through the optical fiber P1. The receiver 1042 may include a tool for converting the optical signal into an electronic signal. For example, in some embodiments, the receiver 1042 may include a suitable photoelectric conversion semiconductor, such as a photovoltaic (PV) cell.
