[0087] The following description, in conjunction with the accompanying drawings, provides a clear and detailed account of some embodiments of this disclosure. However, the described embodiments are merely some, and not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments provided herein are within the scope of protection of this disclosure.
[0088] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open and inclusive, meaning "including, but not limited to"; the terms "first" and "second" should not be construed as indicating or implying relative importance or indicating an upper limit on the number; the term "multiple" means two or more; the term "connection" should be interpreted broadly, for example, "connection" can be a fixed connection, a detachable connection, or an integral part, and can be a direct connection or an indirect connection through an intermediate medium; the use of the terms "applicable to" or "configured to" implies open and inclusive language, which does not exclude the applicability to or configuration of devices to perform additional tasks or steps; descriptions such as "parallel," "perpendicular," "identical," "consistent," and "aligned" are not limited to absolute mathematical theoretical relationships, but also include acceptable error ranges arising in practice, and differences based on the same design concept but due to manufacturing reasons.
[0089] In optical communication technology, to establish information transmission between information processing devices, information is loaded onto light, and the speed of light propagation is used to transmit the information. This light carrying information is called an optical signal. When optical signals are transmitted in optical information transmission equipment, optical power loss can be reduced, enabling long-distance transmission of optical signals. At the same time, the cost of optical information transmission equipment such as optical fibers is lower than that of electrical information transmission equipment such as copper wires. Therefore, optical communication technology can achieve high-speed, long-distance, and low-cost information transmission.
[0090] Information processing equipment typically includes optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., while optical information transmission equipment typically includes optical fibers and optical waveguides. Information processing equipment can only recognize and process electrical signals, while optical communication technology uses optical signals for transmission, requiring optical modules or components to convert between optical and electrical signals.
[0091] Optical modules or optical components enable the mutual conversion between optical signals and electrical signals between information processing devices and optical information transmission devices. In some embodiments, at least one of the optical signal input or output terminals of the optical module or optical component is connected to an optical fiber, and at least one of the electrical signal input or output terminals of the optical module or optical component is connected to an optical network terminal; a first optical signal from the optical fiber is transmitted to the optical module or optical component, which converts the first optical signal into a first electrical signal and transmits the first electrical signal to the optical network terminal; a second electrical signal from the optical network terminal is transmitted to the optical module or optical component, which converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber.
[0092] Since multiple information processing devices can transmit information via electrical signals, at least one of these devices needs to be directly connected to the optical module or optical component, rather than all of them. Here, the information processing device directly connected to the optical module or optical component is also referred to as the host computer of the optical module or optical component. Furthermore, the optical signal input or output terminal of the optical module is called an optical port, and the electrical signal input or output terminal is called an electrical port.
[0093] Figure 1 is a partial architecture diagram of an optical communication system according to some embodiments. As shown in Figure 1, the optical communication system mainly includes a remote information processing device 1000, a local information processing device 2000, a host computer 100, an optical fiber 101, and a network cable 103, wherein the optical fiber 101 is an optical information transmission device, and the network cable 103 is an electrical information transmission device. Optical modules or optical components are electrically connected to the host computer 100.
[0094] In some embodiments, one end of the optical fiber 101 extends toward the remote information processing device 1000, and the other end of the optical fiber 101 is connected to an optical module or optical component. The optical signal can undergo total internal reflection in the optical fiber 101, and the propagation of the optical signal in the direction of total internal reflection can almost maintain its original optical power. The optical signal undergoes multiple total internal reflections in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module or optical component, or vice versa, thereby achieving long-distance information transmission based on low power loss.
[0095] An optical communication system includes one or more optical fibers 101. In some embodiments, the optical fiber 101 is detachably connected to an optical module or optical component; in other embodiments, the optical fiber 101 is non-detachably connected to the optical module or optical component.
[0096] The host computer 100 is configured to provide data signals to the optical module or optical component, or receive data signals from the optical module or optical component, or monitor or control the working status of the optical module or optical component.
[0097] The host computer 100 has a fiber optic interface 102, and the fiber optic cable 101 is inserted into the fiber optic interface 102.
[0098] The host computer 100 also includes an external power interface that can connect to an electrical signal network. In some embodiments, the external power interface includes a Universal Serial Bus (USB) interface or a network cable interface 104. The network cable interface 104 is configured to connect a network cable 103 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the network cable 103.
[0099] One end of the network cable 103 is connected to the local information processing device 2000, and the other end is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. In some embodiments, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103. The host computer 100 generates a second electrical signal based on the third electrical signal. The second electrical signal from the host computer 100 is transmitted to an optical module or optical component. The optical module or optical component converts the second electrical signal into a second optical signal and transmits the second optical signal to an optical fiber 101. The second optical signal is transmitted in the optical fiber 101 to the remote information processing device 1000.
[0100] In some embodiments, a first optical signal from a remote information processing device 1000 is transmitted through an optical fiber 101. The first optical signal from the optical fiber 101 is transmitted to an optical module or optical component. The optical module or optical component converts the first optical signal into a first electrical signal. The optical module or optical component transmits the first electrical signal to a host computer 100. The host computer 100 generates a fourth electrical signal based on the first electrical signal and transmits the fourth electrical signal to a local information processing device 2000.
[0101] In some embodiments, optical modules and optical components are tools for converting optical signals to electrical signals. During the conversion process, the information does not change, but the encoding or decoding method of the information changes.
[0102] In addition to optical network terminals, the host computer 100 also includes optical line terminals (OLTs), optical network equipment (ONTs), or data center servers.
[0103] Figure 2 is a partial structural diagram of a host computer according to some embodiments. As shown in Figure 2, in some embodiments, the host computer 100 may include a circuit board and an optical component 200 disposed within a receiving cavity. The optical component 200 is electrically connected to the circuit board, and the optical component 200 may be disposed on the circuit board. Exemplarily, the optical component 200 may be electrically connected to the circuit board via a flexible circuit board.
[0104] In some embodiments, the optical port of the optical component 200 is connected to the optical fiber 101, thereby enabling the optical component 200 to establish an optical signal connection with the optical fiber 101. For example, the optical component 200 may include an optical fiber component for connecting to the optical fiber 101.
[0105] Figure 3A is a structural diagram of an optical component according to some embodiments; Figure 3B is a structural diagram of an optical component according to some embodiments; Figure 3C is a structural diagram of an optical component according to some embodiments; Figure 3D is a structural diagram of an optical component according to some embodiments; and Figure 3E is an exploded view of an optical component according to some embodiments. As shown in Figures 3A-3E, the optical component 200 may include a housing 210, the interior of which forms a receiving cavity, and the surface of the housing 210 has multiple surfaces.
[0106] In some embodiments, the optical component 200 may include a first light emitting component 220, a second light emitting component 230, a first light receiving component 240, and a second light receiving component 250. The first light emitting component 220, the second light emitting component 230, the first light receiving component 240, and the second light receiving component 250 are respectively connected to the housing 210. Exemplarily, the first light emitting component 220, the second light emitting component 230, the first light receiving component 240, and the second light receiving component 250 are coaxially (TO) packaged, and a plurality of connection holes are formed on the housing 210, through which the first light emitting component 220, the second light emitting component 230, the first light receiving component 240, and the second light receiving component 250 are respectively connected to the housing 210.
[0107] In some embodiments, the first light emitting component 220, the second light emitting component 230, the first light receiving component 240, and the second light receiving component 250 all include pins for electrical connection to a circuit board, such as via a flexible circuit board.
[0108] In some embodiments, the first light emitting component 220 can generate a first wavelength light signal, the second light emitting component 230 can generate a second wavelength light signal, the first light receiving component 240 can receive a third wavelength light signal, and the second light receiving component 250 can receive a fourth wavelength light signal. Exemplarily, the first light emitting component 220 includes a first light-emitting chip for generating the first wavelength light signal; the second light emitting component 230 includes a second light-emitting chip for generating the second wavelength light signal; the first light receiving component 240 includes a first light-receiving chip for receiving the third wavelength light signal; and the second light receiving component 250 includes a second light-receiving chip for receiving the fourth wavelength light signal.
[0109] In some embodiments, the wavelength of the first wavelength optical signal is the first wavelength, the wavelength of the second wavelength optical signal is the second wavelength, the wavelength of the third wavelength optical signal is the third wavelength, and the wavelength of the fourth wavelength optical signal is the fourth wavelength, wherein the first wavelength is less than the second wavelength, the second wavelength is less than the third wavelength, and the third wavelength is less than the fourth wavelength.
[0110] In some embodiments, the optical component 200 may include an optical fiber component 260, which is connected to the housing 210. The optical fiber component 260 is used to connect to an external optical fiber, so as to facilitate the connection of the optical component 200 to an external optical fiber.
[0111] In some embodiments, the optical fiber component 260 may include a first optical fiber adapter 261, an optical fiber 262, and a second optical fiber adapter 263. One end of the optical fiber 262 is connected to the first optical fiber adapter 261, and the other end of the optical fiber 262 is connected to the second optical fiber adapter 263. The first optical fiber adapter 261 is connected to the housing 210, and the second optical fiber adapter 263 is used to connect to an external optical fiber. For example, the end of the external optical fiber is provided with an optical fiber connector, and the second optical fiber adapter 263 is connected to the optical fiber connector.
[0112] In some embodiments, the optical fiber component 260 may include an optical fiber ferrule 264, which is embedded in and connected to a first optical fiber adapter 261. One end of the optical fiber ferrule 264 is located outside the first optical fiber adapter 261, and the other end of the optical fiber ferrule 264 is embedded in the housing 210. The other end of the optical fiber ferrule 264 is located in the first optical fiber adapter 261, and an optical fiber 262 is connected to the optical fiber ferrule 264. Thus, the optical fiber ferrule 264 connects to the optical fiber and inserts one end of the optical fiber ferrule 264 into the housing 210, so as to couple a first wavelength optical signal and a second wavelength optical signal to the optical fiber 262 using the optical fiber ferrule 264, and to transmit a third wavelength optical signal and a fourth wavelength optical signal to the housing 210 using the optical fiber ferrule 264.
[0113] In some embodiments, the optical assembly 200 may include an optical device 270 disposed within a receiving cavity of the housing 210. Exemplarily, the optical device 270 may include a filter, an isolator, etc.
[0114] In some embodiments, the optical device 270 may include multiple filters, which may be located in the optical path from the first light emitting component 220 to the fiber optic component 260. Since light has multiple polarization directions, by changing the angle of the filters located on the optical transmission axis, light in the axial direction can be reflected in different circumferential directions. This facilitates the transmission of the first wavelength optical signal generated by the first light emitting component 220 to the fiber optic component 260, the second wavelength optical signal generated by the second light emitting component 230 to the fiber optic component 260, the third wavelength optical signal input through the fiber optic component 260 to the first light receiving component 240, and the fourth wavelength optical signal input through the fiber optic component 260 to the second light receiving component 250. This allows the second light emitting component 230, the first light receiving component 240, and the second light receiving component 250 to be located in different directions on the housing 210. This allows for the arrangement of a larger number of light emitting and receiving components on the housing 210, enabling the fiber optic component 260 to transmit optical signals through more channels.
[0115] Furthermore, the second optical emitting component 230, the first optical receiving component 240, and the second optical receiving component 250 can make full use of the space between the optical fiber component 260 and the first optical emitting component 220, so that the distance between the optical fiber component 260 and the first optical emitting component 220 is relatively short, thereby shortening the optical path between the optical fiber component 260 and the first optical emitting component 220, the second optical emitting component 230, the first optical receiving component 240, and the second optical receiving component 250.
[0116] In some embodiments, the surface of the housing 210 is formed with a first surface 211, a second surface 212, a third surface 213, a fourth surface 214, a fifth surface 215, and a sixth surface 216. The first surface 211 can be connected to a first light emitting component 220, the second surface 212 can be connected to a second light emitting component 230, the third surface 213 can be connected to a first light receiving component 240, the fourth surface 214 can be connected to a second light receiving component 250, and the sixth surface 216 can be connected to an optical fiber component 260. Exemplarily, the first surface 211, the second surface 212, the third surface 213, the fourth surface 214, the fifth surface 215, and the sixth surface 216 can be located in different directions of the housing 210.
[0117] In some embodiments, the fifth surface 215 is not connected to the light emitting component and the light receiving component. Labels or markings may be affixed to the fifth surface 215. For example, when the light assembly 200 is mounted on a circuit board, the fifth surface 215 is not close to the circuit board, allowing the labels or markings on the fifth surface 215 to be exposed, thus fully utilizing the fifth surface 215 to display information about the light assembly.
[0118] As shown in Figure 3B, in some embodiments, the optical component 200 may include a circuit board 105, with the pins of the second light emitting component 230 embedded and connected to the circuit board 105, such that the second surface 212 is close to the circuit board 105 and the fifth surface 215 is located above the circuit board 105, allowing the fifth surface 215 to be fully exposed. When a label or mark is provided on the fifth surface 215, it facilitates the display of the label or mark on the fifth surface 215. Of course, in some embodiments, the circuit board 105 may also be the circuit board in the host computer 100.
[0119] In some embodiments, one end of the housing 210 forms a first surface 211, and the other end forms a sixth surface 216. The first surface 211 faces the sixth surface 216, and a second surface 212, a third surface 213, a fourth surface 214, and a fifth surface 215 are located between the first surface 211 and the sixth surface 216. The second surface 212, the third surface 213, the fourth surface 214, and the fifth surface 215 may be located in different directions on the housing 210. Exemplarily, the second surface 212, the third surface 213, the fourth surface 214, and the fifth surface 215 may be located in any direction on the housing 210 between the first surface 211 and the sixth surface 216.
[0120] In some embodiments, only one light emitting component or one light receiving component may be disposed on the first surface 211, only one light emitting component or one light receiving component may be disposed on the second surface 212, only one light emitting component or one light receiving component may be disposed on the third surface 213, and only one light emitting component or one light receiving component may be disposed on the fourth surface 214.

[0121] In some embodiments, the first surface 211 is connected to the first optical emitting component 220, and the sixth surface 216 is connected to the optical fiber component 260, so that the first wavelength optical signal generated by the first optical emitting component 220 can be directly transmitted to the optical fiber component 260. For example, the sixth surface 216 is connected to the first optical fiber adapter 261.
[0122] In some embodiments, a first surface 211 and a sixth surface 216 are formed on a first direction of the housing 210 (such as the length direction of the housing 210, hereinafter referred to as the x-direction). The first surface 211 is located at one end of the housing 210, the sixth surface 216 is located at the other end of the housing 210, and a second surface 212, a third surface 213, a fourth surface 214, and a fifth surface 215 are located between the first surface 211 and the sixth surface 216. In this embodiment, the x-direction includes two opposite directions.
[0123] In some embodiments, a second surface 212 and a fifth surface 215 are formed on a second direction of the housing 210 (such as the height direction of the housing 210, hereinafter referred to as the y-direction). Exemplarily, the y-direction may be perpendicular to the x-direction. In this embodiment, the y-direction includes two opposing directions.

For example, the z-direction may be perpendicular to the x-direction, and the z-direction may be perpendicular to the y-direction. In this embodiment, the z-direction includes two opposing directions.
[0125] In some embodiments, the central axis of the second light emitting component 230 does not pass through the center of the housing 210, that is, the second light emitting component 230 is offset from the center of the housing 210. Of course, in some embodiments, the first light receiving component 240 may be offset from the center of the housing 210, and the second light receiving component 250 may be offset from the center of the housing 210, so as to make the structure more compact and improve the utilization rate of the housing 210.
[0126] Figure 4A is a partially exploded view of an optical component according to some embodiments, and Figure 4B is a partially enlarged view of point a in Figure 4A. As shown in Figures 4A and 4B, in some embodiments, the optical device 270 may include a first filter 271 located in the x-direction. Exemplarily, the first filter 271 is located on the axis from the first optical emitting component 220 to the optical fiber component 260, and the first filter 271 is located in the incident optical path of the second optical receiving component 250, with the reflective surface of the first filter 271 facing the second optical receiving component 250. The first filter 271 is used to reflect the fourth wavelength optical signal output from the optical fiber component 260 to the second optical receiving component 250. Since the fourth wavelength optical signal has multiple polarization directions, by changing the angle of the filter located on the optical transmission axis, the light in the axial direction can be reflected in different directions around the circumference. Therefore, the first filter 271 is set in the optical path from the first light emitting component 220 to the optical fiber component 260. By changing the plane where the normal of the first filter 271 and the axis of the optical fiber component 260 are located, the first filter 271 can be adapted to the second light receiving component 250 located in different directions of the housing 210. Thus, the second light receiving component 250 can be located in different directions of the housing 210 through the first filter 271.
[0127] In some embodiments, the optical device 270 may include a second filter 272 located in the x-direction. Exemplarily, the second filter 272 is located on the axis from the first light emitting component 220 to the optical fiber component 260, and is situated in the incident light path of the first light receiving component 240, with its reflective surface facing the first light receiving component 240. The second filter 272 is used to reflect the third wavelength optical signal output from the optical fiber component 260 to the first light receiving component 240. Since the third wavelength signal has multiple polarization directions, by changing the angle of the filter located on the optical transmission axis, the light in the axial direction can be reflected in different directions around the circumference. Therefore, the second filter 272 is set in the optical path from the first light emitting component 220 to the optical fiber component 260. By changing the plane where the normal of the second filter 272 and the axis of the optical fiber component 260 are located, the second filter 272 can be adapted to the first light receiving component 240 located in different directions of the housing 210. Thus, the first light receiving component 240 can be located in different directions of the housing 210 through the second filter 272.
[0128] In some embodiments, the optical device 270 may include a third filter 273, and the second filter 272 is located in the x-direction. Exemplarily, the third filter 273 is located on the axis from the first optical emitting component 220 to the optical fiber component 260, and the third filter 273 is located in the outgoing optical path of the second optical emitting component 230. The reflective surface of the third filter 273 faces the second optical emitting component 230, and the third filter 273 is used to reflect the second wavelength optical signal generated by the second optical emitting component 230 to the optical fiber component 260. Since the second wavelength signal has multiple polarization directions, by changing the angle of the filter located on the optical transmission axis, the light in the axial direction can be reflected in different directions around the circumference. Therefore, the third filter 273 is set in the optical path from the first light emitting component 220 to the optical fiber component 260. By changing the plane where the normal of the third filter 273 and the axis of the optical fiber component 260 are located, the third filter 273 can be adapted to the second light emitting component 230 located in different directions of the housing 210. Thus, the second light emitting component 230 can be located in different directions of the housing 210 through the third filter 273.
[0129] In some embodiments, the optical device 270 may include a first filter 271, a second filter 272, and a third filter 273 arranged sequentially. The first filter 271, the second filter 272, and the third filter 273 are sequentially arranged in the x-direction along the optical path from the first light emitting component 220 to the fiber optic component 260. By adapting the tilt direction of the first filter 271, the second filter 272, and the third filter 273 along the optical path from the first light emitting component 220 to the fiber optic component 260, the second light receiving component 250, the first light receiving component 240, and the second light emitting component 230 can be located in different directions within the housing 210, increasing the flexibility and compactness of the arrangement of the light emitting and receiving components within the housing 210.
[0130] In some embodiments, in the direction from the first light emitting component 220 to the fiber optic ferrule 264, the distance between the second light-emitting chip and the end face of the fiber optic ferrule 264 is greater than the distance between the first light receiving component 240 and the end face of the fiber optic ferrule 264, the distance between the second light-emitting chip and the end face of the fiber optic ferrule 264 is greater than the distance between the second light receiving component 250 and the end face of the fiber optic ferrule 264, and the distance between the first light receiving component 240 and the end face of the fiber optic ferrule 264 is greater than the distance between the second light receiving component 250 and the end face of the fiber optic ferrule 264, thereby facilitating the arrangement of a filter between the first light emitting component 220 and the fiber optic component 260.
[0131] The first wavelength optical signal generated by the first optical emitting component 220 passes sequentially through the third filter 273, the second filter 272, and the first filter 271, and is finally coupled to the fiber optic ferrule 264. The second wavelength optical signal generated by the second optical emitting component 230 is transmitted to the third filter 273, reflected by the third filter 273, and transmitted to the second filter 272. It then passes sequentially through the second filter 272 and the first filter 271, and is finally coupled to the fiber optic ferrule 264. The third wavelength optical signal input through the fiber optic ferrule 264 is transmitted to the first filter 271, passes through the first filter 271, is transmitted to the second filter 272, and is reflected by the second filter 272 before being transmitted to the first optical receiving component 240. The fourth wavelength optical signal input through the fiber optic ferrule 264 is transmitted to the first filter 271, reflected by the first filter 271, and transmitted to the second optical receiving component 250.
[0132] In some embodiments, the optical device 270 may include an isolator 274 located in the optical path from the first optical emitting component 220 to the optical fiber component 260. The isolator 274 can isolate reflected optical signals through optical signals in a specific transmission direction. For example, the isolator 274 is located between the second filter 272 and the third filter 273. The isolator 274 can isolate the first wavelength optical signal and the second wavelength optical signal reflected back by the second filter 272, thereby improving the propagation quality of the optical signal.
[0133] In some embodiments, the optical device 270 may include a fourth filter 275, which is located between the first filter 271 and the second optical receiving component 250. The fourth filter 275 is used to filter out stray light in the fourth wavelength optical signal, ensuring the quality of the optical signal transmitted to the second optical receiving component 250. Exemplarily, the fourth filter 275 may be disposed on top of the second optical receiving component 250.
[0134] In some embodiments, the optical device 270 may include a fifth filter 276, which is located between the second filter 272 and the first optical receiving component 240. The fifth filter 276 is used to filter out stray light in the third wavelength optical signal, ensuring the quality of the optical signal transmitted to the first optical receiving component 240. Exemplarily, the fifth filter 276 may be disposed on top of the first optical receiving component 240.

A third filter 273 is located between the first filter 271 and the second filter 272. The third filter 273 is inclined from the y-direction to the x-direction, the second filter 272 is inclined from the z-direction to the x-direction, and the first filter 271 is inclined from the x-direction to the z-direction. The first wavelength light signal passes through the second filter 272, the third filter 273 and the first filter 271 in sequence; the second wavelength light signal is reflected by the second filter 272 and then passes through the first filter 271; the third wavelength light signal passes through the first filter 271 and the third filter 273 in sequence and then is reflected by the second filter 272; the fourth wavelength light signal is reflected by the first filter 271.
