Description

[Technical field]

[0001] The present application relates to the field of optical communication technology, in particular to optical components, optical modules, and communication devices. [Background technology]

[0002] In modern society, the demand for network throughput capacity is increasing. Optical communication is the mainstream of modern communication methods, and the optical communication network in optical communication is mainly in the form of passive optical network (PON). The communication device mainly includes an optical module, a substrate on which the optical module is installed, and a subrack (optical line terminal (OLT)). Each optical module corresponds to an optical distribution network (ODN) and serves a certain number of users (each optical network unit (ONU) represents a user). As the main components of the optical network, the optical modules of OLT and ONU are responsible for the optical-to-electrical conversion and transmission of network signals, and are the basis for normal communication in the entire network.

[0003] The most important part of an optical module is the bidirectional optical subassembly (BOSA), which is used to implement the transmission and reception of optical signals. The bidirectional optical subassembly is usually packaged in the form of a coaxial transistor-outline can (TO-CAN) to implement a low-cost hermetic package of the chip. A cap on the TO-CAN is used to implement the spatial optical coupling of the optical path from the chip to the optical fiber. A gigabit passive optical network (GPON) part generally includes a transmit TO and a receive TO. According to a standard, transmission and reception are performed using different wavelengths, and multiplexing and demultiplexing of the optical beams are implemented using wavelength division multiplexing (WDM) filters.

[0004] With the upgrade of network bandwidth, GPON network needs to be upgraded from GPON to 10GPON. To ensure compatibility, GPON and 10GPON need to exist in the same ODN network. At present, there are two coexistence modes. One mode is the external WDM1r mode. Both GPON and 10GPON are independent optical modules. After external WDM1r multiplexing is performed on the optical signals output by these two networks, the multiplexed optical signals are sent to the ODN network, so that these two networks coexist with each other. In the other mode, 10GPON parts and GPON parts are integrated into one optical module. The GPON parts and 10GPON parts are combined into an optical module, namely, Combo PON quad optical module. The Combo PON quad optical module mode has the advantages of saving valuable machine room resources and theoretically reducing insertion loss and increasing power budget. Therefore, this mode has received greater support from carriers. This method has now become the mainstream 10GPON method and is the focus of vendor research.

[0005] According to the provisions on the ITU PON field standards, GPON performs transmission by using light with a wavelength of 1490 nm and receives optical signals with a wavelength of 1310 nm, and XGPON performs transmission by using light with a wavelength of 1577 nm and receives optical signals with a wavelength of 1270 nm. Therefore, in the Combo part, a total of four bands used by these two transmitting and receiving groups must share one optical fiber port. In addition, each receiving band has a certain spectral width. For example, the receiving wavelength range of GPON is 1290 nm to 1330 nm, and the receiving wavelength range of 10GPON is 1260 nm to 1280 nm. That is, the difference between the receiving wavelength intervals of GPON and 10GPON in the part is only 10 nm. In addition, the standard protocol requires that the optical split isolation of GPON and 10GPON exceeds 30 dB, which can theoretically only be implemented by using parallel light and a small angle. At present, typical Combo PON optical parts all use parallel optical paths. A collimation lens is installed at the front end of the fiber core. The first filter splits the light at a small angle to separate the light with a wavelength of 1270 nm, and the second filter at 45° on the main optical path separates the remaining light with a wavelength of 1310 nm. A collimation lens needs to be added to the transmission optical path to couple with the fiber core. However, existing networks compatible with GPON and 10GPON have disadvantages such as a relatively large number of optical path parts and devices, a complex coupling process, and a large overall size of the parts. Summary of the Invention

[0006] In consideration of the aforementioned technical problems, the present application provides an optical component, an optical module, and a communication device for separating and transmitting multiple upstream signals and multiple downstream signals by using a simpler structure.

[0007] The present application is implemented by using the following technical solutions.

[0008] According to a first aspect, a specific embodiment of the present application provides an optical component including a base, a light splitting structure arranged on the base, a first filter, and a collimation lens, wherein the base is provided with a light inlet / light outlet, a light splitting surface of the first filter is arranged opposite to the light inlet / light outlet, a first optical signal on a first path is incident on the light splitting surface of the first filter through the light inlet / light outlet, the light splitting surface of the first filter reflects the first optical signal along a second path to a collimation lens, the first path does not coincide with the second path, the collimation lens is arranged on the second path, the collimation lens is configured to convert the first optical signal on the second path into parallel light, an optical signal included in the first optical signal has at least one type of wavelength, and the light splitting structure is arranged on an emergence path of the first optical signal after the first optical signal passes through the collimation lens, and is configured to output the first optical signal adjusted by the collimation lens based on the type of wavelength.

[0009] In the present application, after the plug-in end transmits the first optical signal, the first filter is arranged to directly separate the first optical signal (an upstream signal including an optical signal with a first wavelength and an optical signal with a second wavelength) from the main optical path, thereby avoiding a complex optical component structure that is brought about when the optical signal with the first wavelength and the optical signal with the second wavelength included in the first optical signal are separately separated from the main optical path.

[0011] In this application, the light splitting structure is arranged to split at least two divergent signals separated from a main optical path and output these separated signals from different optical outputs.

[0012] In one possible design, the optical component further includes a first optical receiver and a second optical receiver, the first optical receiver being positioned on the emerging path of the first optical output to receive an optical signal of the first wavelength, and the second optical receiver being positioned on the emerging path of the second optical output to receive an optical signal of the second wavelength.

[0013] In this application, the optical signals output from different optical outlets are received by using different optical receivers.

[0014] In one possible design, the second pathway is parallel to the fourth pathway.

[0015] In the present application, by making the second path of the output optical signal of the first wavelength parallel to the fourth path of the output optical signal of the second wavelength, the first optical receiver receiving the optical signal of the first wavelength and the second optical receiver receiving the optical signal of the second wavelength can be arranged parallel to each other, thereby forming a simpler structure.

[0016] In one possible design, the optical splitting structure further includes a fourth filter disposed on a fourth path between the third filter and the second optical output, the fourth filter transmitting an optical signal of the second wavelength.

[0017] A fourth filter is disposed on the fourth path between the third filter and the second optical output port, and the optical signal of the second wavelength is filtered using the fourth filter, thereby preventing the second optical receiver from receiving any signal other than the optical signal of the second wavelength.

[0018] In one possible design, the optical component further comprises a fifth filter disposed on the base, the base being provided with at least one optical inlet, the optical signals passing through each optical inlet and illuminating the fifth filter, the fifth filter reflecting or transmitting the optical signals passing through the optical inlets to the optical inlet / optical outlet, and the optical signals passing through the optical inlets having different wavelengths.

[0019] In this application, an optical inlet is arranged, and a device for transmitting an upstream signal is arranged at the optical inlet, so that the upstream signal and the downstream signal of the whole device can be transmitted simultaneously.

[0020] In one possible design, the base is provided with two optical inlets, i.e., a first optical inlet and a second optical inlet, the first optical inlet is disposed opposite the optical inlet / optical outlet, a third optical signal on a fifth path passes through the first optical inlet and enters the optical inlet / optical outlet, a light splitting surface of a fifth filter is disposed opposite the second optical inlet, a fourth optical signal on a sixth path enters the light splitting surface of the fifth filter via the second optical inlet, and the fifth filter reflects the fourth optical signal along a seventh path to the optical inlet / optical outlet.

[0021] The optical inputs of the two downstream signals are arranged so that the optical inputs of the optical components meet the GPON requirements and are compatible with downstream signal transmission of 10GPON.

[0022] In one possible design, the base includes a connecting tube body and a support disposed on the connecting tube body, the support including a first support, the first support configured to secure a first filter and a collimation lens, the light inlet / light outlet being disposed on the first support, the connecting tube body configured to secure a fifth filter, and the first light outlet, the second light outlet, and at least one light inlet being disposed on the connecting tube body.

[0023] By disposing the first support and disposing the optical device for separating the upstream signal from the main optical path on the first support, the arrangement of the optical device in the optical component becomes more convenient.

[0024] In one possible design, the collimation lens and the first support are integrally injection molded.

[0025] The first support is integrally injection molded and the first support is attached as a whole, thereby forming a simpler structure.

[0026] In one possible design, the support further includes a second support, the second support configured to secure the light-splitting structure.

[0027] A second support is disposed, and the light-splitting structure is disposed on the second support, thereby avoiding the trouble of disposing the optical device on the support, which is caused by the first support being overly complicated.

[0028] In one possible design, the optical component further includes a first converging lens disposed on the second path and a second converging lens disposed on the fourth path, and the second support is further configured to fix the first converging lens and the second converging lens.

[0029] By disposing the converging lens on the second support, it is possible to avoid providing the converging lens in the first optical receiver and the second optical receiver, thus making the structures of the first optical receiver and the second optical receiver simpler.

[0030] In one possible design, the first converging lens and the second support are integrally injection molded, and the second converging lens and the second support are integrally injection molded.

[0031] The convergent lens and the second support are integrally injection molded, so that the position of the convergent lens on the support is more accurate, thereby avoiding the trouble of disassembly and assembly.

[0032] In one possible design, the first support and the second support are integrally injection molded.

[0033] By integrally injection molding the first support and the second support, the structure of the support in the entire optical component becomes simpler.

[0034] In one possible design, the optical component further comprises a pin and a ferrule, a ferrule hole disposed on the pin, a ferrule fixed in the ferrule hole, one end of the ferrule protruding from the pin, an end of the ferrule protruding from the pin disposed inside the light inlet / light outlet, and the ferrule positioned by the light inlet / light outlet.

[0035] The ferrule of the plug-in end is placed at the light inlet / light outlet for positioning and fixed to the support via a pin, making the connection position between the plug-in end and the support more accurate and the connection more stable.

[0036] In one possible design, the optical component further includes a multiplexing-based transmitter disposed on the base, the multiplexing-based transmitter disposed opposite the optical inlet / optical outlet, and the multiplexing-based transmitter transmits a third optical signal and a fourth optical signal on a fifth path, and the third optical signal and the fourth optical signal on the fifth path are transmitted to the optical inlet / optical outlet.

[0037] In the present application, multiple downstream signals are transmitted by using a multiplexing-based transmitting device, so that the structure for transmitting downstream signals arranged on the base becomes simpler.

[0049] The following describes in detail the technical solutions provided in the embodiments of the present application with reference to the accompanying drawings.

[0050] A specific embodiment of the present application provides an optical component. By using the optical component, multiple upstream signals and / or multiple downstream signals are separated from the main optical path. This avoids a relatively large number of devices on the main optical path and a relatively high cost caused by simultaneously transmitting multiple upstream signals and multiple downstream signals on the main optical path. In addition, the optical component of the present application further includes a base, and multiple optical devices and the like included in the optical component are all arranged on the base, making the arrangement of the optical component more convenient.

[0051] In the present application, the number of the plurality of upstream signals and the number of the plurality of downstream signals can be determined according to a specific scenario. This application is not limited thereto. Of course, the number of the plurality of upstream signals can be the same as or different from the number of the plurality of downstream signals. This application provides an explanation below by using a passive optical network access network compatible with GPON and 10GPON as an example. Of course, the optical components for multiplexing and demultiplexing the plurality of upstream signals and the plurality of downstream signals can alternatively be applied to other scenarios. This application is not limited thereto.

[0052] FIG. 1 illustrates a passive optical network access network compatible with GPON and 10GPON according to a specific embodiment of the present application. As shown in FIG. 1, the passive optical network access network includes an optical line terminal (OLT) and multiple optical distribution network (ODN) devices. The optical line terminal is connected to multiple optical distribution network devices, converts received electrical signals into optical signals, and transmits the optical signals to these optical distribution network devices. The OLT may also be further configured to implement control, management, ranging, and other functions of the ONU. The ODN device is configured to connect to a user-side optical network unit (ONU) and transmit data signals (optical signals) to the user-side ONU devices.

[0053] In this particular embodiment of the present application, the passive optical network access network is a passive optical network access network compatible with GPON and 10GPON. Therefore, the signal transmitted by the OLT to the ODN includes both the optical signal of GPON and the optical signal of 10GPON. The ODN device provides data services that meet GPON or 10GPON requirements to different ONUs based on different ONU types (network bandwidths purchased by users and corresponding to the ONUs).

[0054] Then, the ONU device converts the downstream signal transmitted by the ODN from an optical signal to an electrical signal to provide the user with a network service. The ONU device converts the upstream signal transmitted by the user to the ONU device from an electrical signal to an optical signal, and transmits the optical signal to the OLT via the ODN.

[0055] According to the provisions on standards in the field of passive optical networks (PON) provided by the International Telecommunication Union (ITU), GPON uses light with a wavelength of 1490 (1480-1500) nm to transmit downstream signals and light with a wavelength of 1310 nm to transmit upstream signals, while XGPON uses light with a wavelength of 1577 (1575-1580) nm to transmit downstream signals and light with a wavelength of 1270 nm to transmit upstream signals. That is, the difference between the receiving wavelength intervals of GPON and 10GPON in the component is only 10 nm. Therefore, in a quad optical component, two groups of transmitted and received optical signals, that is, a total of four optical signals with different wavelengths, need to share one optical fiber port.

[0056] The OLT in this particular embodiment of the present application further includes a quad optical module, which enables the OLT to receive a 1490-nm upstream signal of GPON and a 1577-nm upstream signal of XGPON, and transmits a 1270-nm downstream signal of GPON and a 1310-nm downstream signal of XGPON to the ONU for the OLT.

[0057] In the following, the structure of a quad optical device for transmitting two upstream optical signals and two downstream optical signals is described.

[0058] 2 is a schematic structural diagram of a quad optical component according to a specific embodiment of the present application. As shown in FIG. 2, the quad optical component includes a base, a light dividing structure, a first filter, a collimation lens, a second filter, and a third filter disposed on the base.

[0059] The base is further provided with a light inlet / light outlet, a first light inlet, a second light inlet, a first light outlet, and a second light outlet. A plug-in end is further arranged at the light inlet / light outlet, and the plug-in end receives an optical signal of a first wavelength and / or an optical signal of a second wavelength (first optical signal) and transmits a third optical signal and a fourth optical signal. A first optical transmitter and a second optical transmitter are further arranged at the first light inlet and the second light inlet, respectively. The first optical transmitter transmits a third optical signal, and the second optical transmitter transmits a fourth optical signal. A first optical receiver and a second optical receiver are further arranged at the first light outlet and the second light outlet, respectively. The first optical receiver receives the optical signal of the first wavelength transmitted from the light inlet / light outlet, and the second optical receiver receives the optical signal of the second wavelength transmitted from the light inlet / light outlet.

[0060] In one example, the plug-in end receives a first optical signal, the first optical signal including an optical signal of a first wavelength and an optical signal of a second wavelength. The optical signal of the first wavelength is an upstream signal meeting 10GPON requirements, the optical signal of the first wavelength being an optical signal of a frequency band of 1260 nm to 1280 nm. The optical signal of the second wavelength is a downstream signal meeting 10GPON requirements, the optical signal of the second wavelength being an optical signal of 1300 nm to 1320 nm. Of course, the optical signal of the first wavelength may also be referred to as an optical signal of 1270 nm, and the optical signal of the second wavelength may also be referred to as an optical signal of 1310 nm. The third optical signal transmitted by the first optical transmitter is an upstream signal meeting GPON requirements, the third optical signal being an optical signal of a frequency band of 1480 nm to 1500 nm. The fourth optical signal transmitted by the second optical transmitter is an upstream signal meeting 10GPON requirements, the fourth optical signal being an optical signal of 1575 nm to 1580 nm. Of course, alternatively, the first wavelength optical signal may be a 1310 nm optical signal, the second wavelength optical signal may be a 1270 nm optical signal, the third wavelength optical signal may be a 1490 nm optical signal, and the fourth wavelength optical signal may be a 1577 nm optical signal.

[0061] The first optical signal received by the plug-in end is the first optical signal on the first path, and the first optical signal on the first path is transmitted after passing through the optical inlet / outlet. The first optical signal includes an optical signal of a first wavelength and an optical signal of a second wavelength, and the optical signal of the first wavelength and the optical signal of the second wavelength are diverging optical signals.

[0062] The light splitting surface of the first filter is disposed facing the light inlet / light outlet, and the first optical signal passing through the light inlet / light outlet can be irradiated onto the light splitting surface of the first filter. The first filter reflects the first optical signal (the optical signal of the first wavelength and the optical signal of the second wavelength). That is, the first filter reflects the optical signal in the frequency band (wavelength) of 1260 nm to 1320 nm.

[0063] The first filter reflects the first optical signal to a second path, and the second path does not match the first path. Specifically, since the paths of the first optical signal before and after it is reflected by the first filter are different, it can be ensured that the first optical signal does not pass through the optical inlet / outlet in the opposite direction along the first path.

[0064] A collimation lens is further included on the second path where the first filter reflects the first optical signal, and the first optical signal reflected by the first filter to the second path illuminates the collimation lens. The collimation lens is a lens that converts a non-parallel optical signal into a parallel optical signal and then transmits the parallel optical signal. The first optical signal that illuminates the collimation lens passes through the collimation lens, and the optical signal included in the first optical signal that has passed through the collimation lens is a parallel optical signal.

[0065] After the first optical signal passes through the collimation lens, a light dividing structure is further disposed in the emergence direction of the first optical signal. The light dividing structure is configured to output the optical signal of the first wavelength and the optical signal of the second wavelength contained in the parallel first optical signal through different optical output ports. The light dividing structure may have a number of forms, and is not limited thereto in the present application.

[0066] Optionally, a second filter may be further disposed between the collimation lens and the light dividing structure. The second filter may transmit optical signals in the frequency band of 1260 nm to 1320 nm. The second filter is configured to filter optical signals that pass through the collimation lens and are in another frequency band, other than the optical signals in the frequency band of 1260 nm to 1320 nm, thereby preventing optical signals that pass through the second filter and enter the light dividing structure from including optical signals in another frequency band, other than the optical signals in the frequency band of 1260 nm to 1320 nm.

[0067] A first optical inlet is disposed on the side of the base far from the optical inlet / optical outlet, and an optical inlet / optical outlet and a first optical inlet are disposed on both sides of the first filter, respectively. A first optical transmitter is further disposed on the first optical inlet, and the first optical transmitter disposed on the first optical inlet transmits a third optical signal, and the path of the third optical signal is an A-th path. The third optical signal is a convergent optical signal. The third optical signal on the A-th path passes through the first filter and is transmitted to the optical inlet / optical outlet, so that the plug-in end can receive the third optical signal. In a special example, the phase difference between the first path and the A-th path is 180°.

[0068] A second optical inlet is disposed between the first filter and the first optical inlet, and a second optical transmitter is further disposed at the second optical inlet, and the second optical transmitter disposed at the second optical inlet transmits a fourth optical signal, the fourth optical signal being an optical signal on a B-th path. The fourth optical signal on the B-th path overlaps with the third optical signal on the A-th path. The fourth optical signal is a convergent optical signal.

[0069] The third filter is disposed at a position where the Bth path intersects with the Ath path. In one example, when the third optical signal is a horizontal optical signal, the fourth optical signal overlaps with the third optical signal.

[0070] The third filter reflects the fourth optical signal and transmits the third optical signal. The light splitting surface of the third filter is disposed facing the second optical inlet. The fourth optical signal on the Bth path is incident on the light splitting surface of the third filter, and the third filter reflects the fourth optical signal along the Cth path. The fourth optical signal reflected by the third filter onto the Cth path is transmitted to the optical inlet / optical outlet, allowing the plug-in end to receive the fourth optical signal.

[0071] Optionally, a fourth filter is further disposed on the base on the Ath path between the first optical inlet and the third filter, the fourth filter transmitting the third optical signal.

[0072] In this particular embodiment of the present application, each filter is merely a particular embodiment of the present application, and other filters may alternatively be added to the optical components of the present application depending on the functional requirements based on this embodiment of the present application.

[0073] It should be noted that the cross-sectional shape of each filter described above in the present application is a rectangle, which is merely a specific example in the present application and cannot be used to limit the present application. The cross-sectional shape of the filter in the present application can alternatively be set to any other shape, such as a trapezoid, as long as the shape can be used to reflect an optical signal of a specific wavelength. This application is not limited thereto. In one example, when the cross-sectional shape of the filter is a trapezoid, the hypotenuse of the trapezoid is the reflective surface of the filter.

[0074] In this application, after the plug-in end receives the first optical signal, the first filter is directly used to separate the first optical signal (an upstream signal including an optical signal with a first wavelength and an optical signal with a second wavelength) from the main optical path, which avoids the problems of a complex optical component structure and the use of excessive collimation lenses that are caused when the optical signal with the first wavelength and the optical signal with the second wavelength included in the first optical signal are separately separated from the main optical path, thereby simplifying the structure of the optical components and reducing the cost of the optical components.

[0075] 3 illustrates a light splitting structure according to a specific embodiment of the present application. As shown in FIG. 3, the light splitting structure is configured to split a first optical signal, which is transmitted by a collimation lens and includes an optical signal of a first wavelength and an optical signal of a second wavelength, into an optical signal of the first wavelength and an optical signal of the second wavelength, and output these optical signals through different optical output ports. As shown in FIG. 3, the light splitting structure includes a fifth filter, a sixth filter, and a seventh filter.

[0076] The optical signal of the first optical signal transmitted through the collimation lens includes an optical signal of a first wavelength and an optical signal of a second wavelength, and the optical signal of the first wavelength and the optical signal of the second wavelength are both parallel optical signals.

[0077] A fifth filter is further disposed in a direction in which the first optical signal passes through the collimation lens. The fifth filter is configured to reflect an optical signal of the first wavelength and transmit an optical signal of the second wavelength, or the fifth filter is configured to reflect an optical signal of the second wavelength and transmit an optical signal of the first wavelength. That is, the fifth filter may be configured to filter both an optical signal of the first wavelength and an optical signal of the second wavelength. This application is not limited thereto.

[0078] In the following, a detailed description is provided by using an example in which the fifth filter reflects the optical signal of the second wavelength and transmits the optical signal of the first wavelength. The light splitting surface of the fifth filter is not perpendicular to the light splitting surface passing through the fifth filter, thereby avoiding the fifth filter from reflecting the optical signal of the second wavelength in the direction opposite to the second path.

[0079] A first light outlet and a second light outlet are further disposed on the base corresponding to the light dividing structure.

[0080] The first optical output port is disposed on the base in a transmission direction of an optical signal having the first wavelength passing through the fifth filter. A first optical receiver is disposed inside the first optical output port, and the first optical receiver receives the optical signal having the first wavelength and transmits the optical signal having the first wavelength to a user side.

[0081] Optionally, a converging lens is further disposed between the first optical output and the fifth filter, the converging lens being configured to convert the parallel light of the optical signal of the first wavelength passing through the fifth filter into a converging light.

[0082] The fifth filter reflects the optical signal of the second wavelength along the third path. A sixth filter is further disposed in a direction in which the fifth filter reflects the optical signal of the second wavelength along the third path, and the sixth filter reflects the optical signal of the second wavelength. The sixth filter reflects the optical signal of the second wavelength along a fourth path, and the fourth path does not coincide with the third path.

[0083] In one example, the fifth filter and the sixth filter are arranged parallel to each other. When the fifth filter is parallel to the sixth filter, the direction in which the optical signal of the second wavelength is reflected is the same as and parallel to the direction in which the first optical signal passes through the collimation lens.

[0084] The second optical output is disposed on the fourth path where the sixth filter reflects the optical signal of the second wavelength. A second optical receiver is disposed at the second optical output, and the second optical receiver is configured to receive the optical signal of the second wavelength and transmit the optical signal of the second wavelength to a corresponding user side.

[0085] Optionally, a converging lens and a seventh filter are further disposed between the second optical output and the sixth filter, and the optical signal of the second wavelength is transmitted through the converging lens and the seventh filter. The seventh filter and the converging lens are disposed to overlap. The seventh filter is configured to filter optical signals other than the optical signal of the second wavelength to reduce other mixed signals received by the second optical receiver. The converging lens is configured to convert the parallel light of the optical signal of the second wavelength reflected by the sixth filter into a converging light, facilitating signal reception performed by the second optical receiver.

[0086] In this particular embodiment of the present application, the first optical transmitter and the second optical transmitter may be independent structures. In the following, the specific embodiment will be used to provide a detailed description separately.

[0087] It should be noted that in this particular embodiment of the present application, the light dividing structure includes a converging lens, which is merely an example. In this particular embodiment of the present application, the light dividing structure may alternatively not include a converging lens. When the light dividing structure does not include a converging lens, the first optical receiver and the second optical receiver disposed inside the first optical output and the second optical output include a converging lens, respectively, so that the parallel light of the optical signal of the first wavelength passing through the fifth filter is converted into a converging light, and the parallel light of the optical signal of the second wavelength reflected by the sixth filter is converted into a converging light.

[0088] FIG. 4 is a schematic structural diagram of another quad optical component according to a specific embodiment of the present application. As shown in FIG. 4, the schematic structural diagram of the quad optical component shows an improvement based on the structure of the quad optical component shown in FIG. 2. The quad optical component includes a base, a light splitting structure, a first filter, a second filter, a fourth filter, and a collimation lens disposed on the base. In the example shown in FIG. 4, the base is further provided with a light inlet, a first light outlet, and a second light outlet. The light inlet / light outlet, the first light outlet, and the second light outlet disposed on the base, and the first filter, the collimation lens, the second filter, the light splitting structure, and the fourth filter disposed on the base have the same structure, position, and function as the corresponding parts in FIG. 2 and FIG. 3. Details will not be described in this application.

[0089] The optical inlet disposed on the base is disposed at the same position as the first optical inlet shown in Fig. 2. A third optical transmitter is further connected to the optical inlet shown in Fig. 4, and the third optical transmitter is configured to transmit a third optical signal and a fourth optical signal through multiplexing. The third optical signal and the fourth optical signal may be the same as those shown in Fig. 2. Details will not be described in this application.

[0090] FIG. 5 illustrates a third optical transmitter according to a specific embodiment of the present application. As shown in FIG. 5, the third optical transmitter includes a 1557-nm laser signal transmitter, a 1490-nm laser signal transmitter, and a wavelength division multiplexing filter (WDM filter). The wavelength division multiplexing filter (multiplexing-based transmitting device) includes a wavelength division multiplexing chip (WDM chip) and a laser signal transmitter. The 1557-nm laser signal transmitter is configured to transmit a 1557-nm laser signal, and the wavelength division multiplexing chip is coupled to a signal output by the 1557-nm laser signal transmitter. The 1490-nm laser signal transmitter is configured to transmit a 1490-nm laser signal, and the wavelength division multiplexing chip is electrically connected to a signal output by the 1490-nm laser signal transmitter. The wavelength division multiplexing chip is configured to perform modulation to obtain multiplexed third and fourth optical signals according to the signal output by the 1557-nm laser signal transmitter and the signal output by the 1490-nm laser signal transmitter. The laser signal transmitter is connected to the wavelength division multiplexing chip and transmits a corresponding laser signal. The third and fourth optical signals transmitted through multiplexing by the laser signal transmitter are output through an optical input port.

[0091] Optionally, the signal output interface of the 1557-nm laser signal transmitter and the signal output interface of the 1490-nm laser signal transmitter are both connected to a backlight detection device. The backlight detection device is configured to determine the light intensity of the acquired signal transmitted by the 1557-nm laser signal transmitter and the acquired signal transmitted by the 1490-nm laser signal transmitter based on these signals. When the backlight detection device determines that the light intensity of the light signal transmitted by each laser signal transmitter is below a predetermined threshold, it further transmits information to the corresponding laser signal transmitter, and the information is used to instruct the laser signal transmitter to increase the light intensity of the transmitted light signal.

[0092] In the above-mentioned embodiment of the present application, the third optical transmitter transmits the third optical signal and / or the fourth optical signal through multiplexing. The structure of the quad optical component is simpler because the optical component uses fewer devices to achieve the same effect.

[0093] In a specific example, the backlight detection device stores a light intensity threshold corresponding to a 1490-nm laser signal transmitter and a light intensity threshold corresponding to a 1557-nm laser signal transmitter. The backlight detection device obtains the intensity of the light signal transmitted by the 1557-nm laser signal transmitter from the signal output interface of the 1557-nm laser signal transmitter. The backlight detection device compares the intensity of the light signal transmitted by the 1557-nm laser signal transmitter with the stored light intensity threshold corresponding to the 1557-nm laser signal transmitter. If the intensity of the light signal transmitted by the 1557-nm laser signal transmitter is within the range of the light intensity threshold, the backlight detection device does not perform any processing, and if the intensity of the light signal transmitted by the 1557-nm laser signal transmitter is outside the range of the light intensity threshold, the backlight detection device sends instruction information to the 1557-nm laser signal transmitter. The 1557-nm laser signal transmitter transmits the light intensity of the transmitted light signal, which is adjusted according to the instruction information.

[0094] Optionally, the third optical transmitter further includes a converging lens (cap), and the cap is disposed on the path of the third optical signal and the fourth optical signal transmitted by the laser signal transmitter through multiplexing. The converging lens may be disposed on the package structure or base of the third optical transmitter. This application is not limited thereto.

[0095] In the following, the base will be described in detail by using a specific embodiment.

[0096] 6 is a schematic structural diagram of an optical component according to a specific embodiment of the present application. As shown in FIG. 6, the optical component includes a base, an optical device disposed on the base, and a plug-in end 603. The optical device includes the first filter, the second filter, the third filter, the fourth filter, the light splitting structure, and the collimation lens, etc., of FIG. 2 to FIG. 5.

[0097] The base includes a support 601 and a connecting pipe body 602 , and the support 601 is disposed inside the connecting pipe body 602 .

[0098] In this particular embodiment of the present application, the collimation lens, the first filter, and the plug-in end 603 are disposed on the support 601, and the light-splitting structure and the third filter are disposed on the connecting tube body 602.

[0099] The structures of the support 601, the collimation lens, the first filter, and the plug-in end 603 disposed on the support 601 will be described in detail below.

[0100] 7 is a schematic structural diagram of a support according to a specific embodiment of the present application. As shown in FIG. 7, the support includes a support 601, a collimation lens 701, a first filter 702, and a first connection hole 703 disposed on the support 601.

[0101] One side of the support 601 has a first connection hole 703, which is used to receive the plug-in end 603. The shape and size of the first connection hole 703 are consistent with those of the plug-in end 603 inserted into the first connection hole 703. The plug-in end 603 is configured to input / output an optical signal. In this embodiment of the present application, the plug-in end 603 can receive a first optical signal on a first path, where the first optical signal includes an optical signal of a first wavelength and an optical signal of a second wavelength. The optical signal of the first wavelength and the optical signal of the second wavelength may be the same as those shown in FIG. 1 and FIG. 2.

[0102] The other side of the support 601 relative to the first connection hole 703 further includes a first filter mounting location 704, at which a first filter 702 can be disposed.

[0103] The support 601 is further provided with a first optical through hole 705 penetrating the support 601. One side of the first optical through hole 705 penetrating the first connection hole 703, and the other side of the first optical through hole 705 penetrating the first filter mounting location 704. Optionally, the first optical through hole 705 is further aligned with the first path to avoid signal interference caused when the first optical signal illuminates the inner wall of the first optical through hole 705.

[0104] The optical signal of the first wavelength and the optical signal of the second wavelength output by the plug-in end 603 are irradiated through a first optical through-hole 705 onto a first filter 702 disposed at a first filter mounting location 704 .

[0105] In one example, when the cross section of both the first light through hole 705 and the first filter mounting location 704 are cylindrical, the included angle between the axis of the first light through hole 705 and the end face of the first filter mounting location 704 is not equal to 90 degrees. That is, the first filter mounting location 704 is disposed obliquely with respect to the axis of the first light through hole 705. The first filter 702 is disposed at the first filter mounting location 704, and the first filter 702 disposed at the first filter mounting location 704 reflects the first optical signal along a second path. The first path does not coincide with the second path. The second path along which the first filter 702 on the support 601 reflects the first optical signal further includes a second light through hole 706, and the second light through hole 706 penetrates the first light through hole 705.

[0106] The collimation lens 701 is disposed in the second light through hole 706. The first optical signal reflected by the first filter 702 along the second path passes through the collimation lens 701. The collimation lens 701 is configured to convert the diverging first optical signal reflected by the first filter 702 to the collimation lens 701 into a parallel first optical signal for output. That is, the first optical signal input to the collimation lens 701 is a diverging optical signal, and the first optical signal output by the collimation lens 701 is a parallel optical signal.

[0107] Optionally, the support 601 can be processed and molded by using injection molding technology. The first filter 702 can be directly installed on the first filter mounting location 704 of the injection molded support 601. Alternatively, the first filter 702 can be placed at a corresponding position of the injection molded model during the injection molding process of the support 601, so that the injection molded support 601 and the first filter 702 form a whole. The collimation lens 701 can be placed at a corresponding position of the injection molded model during the injection molding process of the support 601, so that the injection molded support 601 and the collimation lens 701 form a whole.

[0108] The first optical signal (including an optical signal of a first wavelength and an optical signal of a second wavelength) passing through the collimation lens 701 is output via a first optical output port and a second optical output port arranged on the connection tube main body 602.

[0109] The connecting pipe body 602 has a shell structure with a central portion cut open, and includes a shell 604 and a through hole 605 .

[0110] A support 601 is disposed on one side of the through hole 605. One side of the first connection hole 703 of the support 601 is close to the end face of the connecting pipe body 602, and one side of the first filter mounting location 704 on the support 601 is far away from the end face of the connecting pipe body 602. The first optical signal passes through the collimation lens 701, and the first optical receiver and the second optical receiver are further disposed on the shell 604 of the connecting pipe body 602, and the optical signal of the first wavelength and the optical signal of the second wavelength passing through the collimation lens are received via the first optical receiver and the second optical receiver.

[0111] The optical component includes an optical division structure and a plurality of optical receivers. The optical division structure is configured to output an optical signal of a first wavelength and an optical signal of a second wavelength contained in the first optical signal through different optical exits. The plurality of optical receivers are disposed at different optical exits, and an optical receiver is disposed at each optical exit. The structure of the receiving end may be shown in FIG. 3. Details will not be described again in this application.

[0112] A first optical transmitter is disposed on the other side of the through hole 605 where the support 601 is not disposed, and the first optical transmitter transmits a third optical signal along the Ath path to the support 601. The third optical signal on the Ath path passes through the first optical through hole 705 and the first connection hole 703 of the support 601, so that the plug-in end 603 can receive the third optical signal.

[0113] Optionally, a fourth filter is further disposed in the through-hole 605 between the support 601 and the first optical transmitter, the fourth filter being configured to transmit a third optical signal.

[0114] A second optical transmitter is further disposed in the shell 604 between the support 601 and the first optical transmitter, and the second optical transmitter transmits a fourth optical signal to the support 601 along a B-th path, which passes through the through hole 605. A third filter is further disposed in the through hole 605 at a position where the B-th path intersects with the through hole 605. The fourth optical signal transmitted by the second optical transmitter illuminates the light splitting surface of the third filter, and the third filter reflects the fourth optical signal along a C-th path. The fourth optical signal on the C-th path passes through the first optical through hole 705 and the first connection hole 703 of the support 601, so that the plug-in end 603 can receive the fourth optical signal.

[0115] The plug-in end 603 includes a pin 606, in which a plug-in hole 607 is disposed. A ferrule 608 is further disposed in the plug-in hole 607 on the side of the plug-in end 603 that is connected to the support 601, and a corresponding signal is received or transmitted by using the ferrule 608. An optical fiber is further disposed in the plug-in hole 607 on the side of the plug-in end 603 that is far from the support 601, and the optical fiber is used to transmit the received or transmitted signal.

[0116] Optionally, the ferrule 608 is placed in the first connection hole 703, which is configured to position the plug-in end 603 and the ferrule 608. When the ferrule 608 is placed in the first connection hole 703, the pin 606 is connected against the end face of the support 601 in which the first connection hole 703 is located.

[0117] In this particular embodiment of the present application, the first light exit and the second light exit on the connecting pipe body can alternatively be replaced with the light exit shown in Fig. 4. The first light exit on the connecting pipe body is arranged in the same manner as the second light exit, and will not be described in detail in this application.

[0118] In this particular embodiment of the present application, the aforementioned support 601 does not include a light-splitting structure, which is merely an example of the present application. A light-splitting structure may alternatively be disposed on the support 601. If the support 601 includes a light-splitting structure, the light exit does not include a light-splitting structure.

[0119] The support in this particular embodiment of the present application may include a first support and a second support. The first support may be the support 601 shown in Figures 6 and 7. The second support may be configured to install a light dividing structure. The second support provided in this particular embodiment of the present application will be described in detail below.

[0120] Fig. 8 illustrates a second support according to a specific embodiment of the present application. As shown in Fig. 8, the second support 801 further includes a fifth filter mounting location 802 in a direction in which the first optical signal (including the optical signal of the first wavelength and the optical signal of the second wavelength) passes through the collimation lens, and a fifth filter is disposed at the fifth filter mounting location 802. The first optical signal passing through the collimation lens illuminates the fifth filter disposed at the fifth filter mounting location 802. The fifth filter transmits the optical signal of the first wavelength and reflects the optical signal of the second wavelength along a third path.

[0121] If the cross section of the fifth filter is rectangular, there is an included angle between the fifth filter located at the fifth filter mounting location 802 and the first optical signal. In one example, the included angle between the end face of the fifth filter mounting location 802 and the first optical signal passing through the fifth filter is not equal to 90 degrees. That is, the first optical signal does not illuminate the fifth filter perpendicularly. The included angle between the end face of the fifth filter mounting location 802 and the first optical signal passing through the fifth filter is set based on the specific position of each structure in the second support 801. This application is not limited in this respect.

[0122] The second support 801 further includes a first convergent lens mounting location 806 in a direction in which the optical signal of the first wavelength passes through the fifth filter, and a first convergent lens is disposed at the first convergent lens mounting location 806. The first convergent lens disposed at the first convergent lens mounting location 806 converts the optical signal of the first wavelength irradiating the first convergent lens from parallel light to convergent light. A first optical receiver is further disposed on a first optical output port on the connecting pipe main body 602 corresponding to the first convergent lens mounting location 806, and the first optical receiver is configured to receive the optical signal of the first wavelength.

[0123] The second support 801 further includes a sixth filter mounting location 803 in a direction in which the fifth filter reflects the optical signal of the second wavelength, and the sixth filter is disposed in the sixth filter mounting location 803. The sixth filter disposed in the sixth filter mounting location 803 reflects the optical signal of the second wavelength along a fourth path, and the fourth path does not coincide with the third path. According to actual requirements, a specific position of the fourth path is set, and the present application is not limited thereto.

[0124] Optionally, the second support 801 further comprises a seventh filter mounting location 804 in a direction in which the sixth filter reflects the optical signal of the second wavelength, and the seventh filter is disposed at the seventh filter mounting location 804. The seventh filter is a filter for filtering an optical signal of another wavelength other than the optical signal of the second wavelength. The reflection surface of the seventh filter disposed at the seventh filter mounting location 804 is perpendicular to the optical signal of the second wavelength reflected by the sixth filter.

[0125] The second support 801 further includes a second convergent lens mounting location 807 in a direction in which the optical signal of the second wavelength passes through the seventh filter, and a second convergent lens is disposed at the second convergent lens mounting location 807. The second convergent lens disposed at the second convergent lens mounting location 807 converts the optical signal of the second wavelength irradiating the second convergent lens from parallel light to convergent light. A second optical receiver is further disposed on the connecting pipe main body 602 corresponding to the second convergent lens mounting location 807, and the second optical receiver is configured to receive the optical signal of the second wavelength passing through the convergent lens.

[0126] Optionally, the sixth filter mounting location 803 is parallel to the fifth filter mounting location 802, the sixth filter 805 disposed at the sixth filter mounting location 803 is parallel to the fifth filter disposed at the fifth filter mounting location 802, and the optical signal of the first wavelength passing through the fifth filter is parallel to the optical signal of the second wavelength reflected by the sixth filter 805. By paralleling the optical signal of the first wavelength passing through the fifth filter to the optical signal of the second wavelength reflected by the sixth filter 805, the first and second converging lenses can be disposed parallel to each other, and the first and second optical receivers can be disposed parallel to each other.

[0127] The schematic structural diagram of the second support shown in Fig. 8 may alternatively not include the first convergent lens mounting location, the second convergent lens mounting location, and the convergent lenses disposed at these convergent lens mounting locations. If the second support 801 does not include a convergent lens mounting location and a convergent lens, then the first optical receiver and the second optical receiver each include a convergent lens.

[0128] Optionally, the aforementioned support 601 and the second support 801 may be two independent injection molded parts, both of which are disposed in the connecting pipe body 602. Of course, the support 601 and the second support 801 may alternatively form a whole. Alternatively, the support 601 and the second support 801 may form a whole, including the support 601 and the second support 801 being injection molded at the same time, or the support 601 and the second support 801 are injection molded separately and then connected as a whole.

[0129] In the present application, the support body is integrally molded and the connecting pipe body is fixed in structure, and the support body is disposed on the connecting pipe body, so that the structure of the optical components is simpler. In addition, various optical devices are disposed on the base formed by the support body and the connecting pipe body, so that the arrangement of the optical components is more convenient. Furthermore, the collimation lens and the support body are integrally injection molded, so that the position of the collimation lens relative to the optical path is more accurate.

[0130] Figure 9 is a schematic diagram of a support according to a specific embodiment of the present application. As shown in Figure 9, the support 901 includes the support 601 shown in Figure 7 and the second support 801 shown in Figure 8, and the support 601 and the second support 801 form a whole. The structure of the aforementioned support is the same as that shown in Figures 7 and 8. Details will not be described in this application.
