Description

[Technical field]

[0001] The present application relates to the field of optical communications, and in particular to optical components, optical switching complete interconnect systems, and communication systems. [Background technology]

[0002] This application claims priority to Chinese Patent Application No. 202210163877.7, entitled “OPTICAL COMPONENT, OPTICAL SWITCHING FULLY-INTERCONNECTED SYSTEM, AND COMMUNICATION SYSTEM,” filed with the State Intellectual Property Office of the People's Republic of China on February 22, 2022, which is hereby incorporated by reference in its entirety.

[0003] With the development of communication technology, the requirements for the capacity of routing and switching devices are also increasing. Current switching technologies are usually related to electrical switching systems and optical switching systems. Electrical switching systems are based on packet switching, which can realize switching delays at the microsecond level, and are the mainstream solution for realizing high-speed switching with fine granularity. Optical switching systems are based on optical wavelength or optical link switching, and are currently capable of realizing switching in milliseconds to seconds. Optical switching systems have large bandwidth but low speed.

[0004] At present, the system architecture of the electrical switching system and the optical switching system has several possible implementations: In the electrical switching full interconnection architecture shown in FIG. 1, service nodes are directly connected to each other to realize high-speed switching communication between multiple service nodes; In the electrical switching star interconnection architecture shown in FIG. 2, multiple service nodes are in an indirect switching connection state through some centralized switching nodes to realize high-speed switching communication between multiple service nodes; However, after the number of channels in the electrical switching system shown in FIG. 1 and FIG. 2 is determined, future bandwidth expansion can only be performed by increasing the single channel speed, and the improvement of the single channel speed is limited. Therefore, there is a problem that the room for increasing the bandwidth is limited. In the optical switching star interconnection architecture shown in FIG. 3, multiple service nodes are in an indirect switching connection state through some centralized switching nodes to realize high-speed switching communication between multiple service nodes; In the optical switching system, the bandwidth can be increased according to the service requirements, but in the switching star interconnection architecture, the loss of the entire optical link is large due to the loss of N*N optical switches and four backplane traversals.

[0005] Therefore, there is currently an urgent need for optical components that can increase bandwidth and reduce optical link losses according to service requirements. Summary of the Invention

[0006] SUMMARY OF THE DISCLOSURE Embodiments of the present application provide optical components, optical switching complete interconnect systems, and communication systems to reduce backplane losses of optical signals between optical components and switching nodes.

[0007] According to a first aspect, the present application provides an optical component. The optical component specifically includes a service processing module, an optical / electrical conversion module, a multiplexer, an optical switching switch, an optical receiving module, and an optical connector. When the optical component serves as a transmitting end, a first electrical signal generated by the service processing module is converted by the optical / electrical conversion module to generate a first optical signal, and the first optical signal is multiplexed by using the multiplexer and output to the optical component of the next hop through the optical switching switch and the optical connector.

The second optical component includes a second service processing module, a second optical / electrical conversion module, a second multiplexer, a second optical switching switch, a second optical receiving module, and a second optical connector. The quantity of output ports of the first optical switching switch and the quantity of output ports of the second optical switching switch are equal to or greater than the quantity of optical components in the optical switching complete interconnection system minus 1. An electrical signal generated by a first service processing module is converted by a first optical / electrical conversion module to generate a first optical signal, the first optical signal is multiplexed by using a first multiplexer, and transmitted to a second optical connector through a first optical switching switch and a first optical connector. An electrical signal generated by a second service processing module is converted by a second optical / electrical conversion module to generate a second optical signal, the second optical signal is multiplexed by using a second multiplexer, and transmitted to the first optical connector through a second optical switching switch and a second optical connector.

[0015] In this embodiment, the optical switching switches are integrated into the optical components in the optical switching fully interconnected system, thereby forming a system architecture in which the optical components in the optical switching fully interconnected system are directly connected to each other, and direct service switching can be performed between the optical components. In this manner, the backplane loss of the optical signals between the optical components and the switching nodes is reduced.

[0016] In a possible implementation, the first optical switching switch is a 1*M optical switching switch, where M is a positive integer greater than or equal to N-1, and the second optical switching switch is a 1*M optical switching switch, where M is a positive integer greater than or equal to N-1.

[0017] In another possible implementation, the optical switching complete interconnection system further includes a third optical component. Any two of the first optical component, the second optical component, and the third optical component are directly connected to each other. The third optical component includes a third service processing module, a third optical / electrical conversion module, a third multiplexer, a third optical switching switch, a third optical receiving module, and a third optical connector. The electrical signal generated by the third service processing module in the third optical component is converted by the third optical / electrical conversion module to generate a third optical signal, and the third optical signal is multiplexed by using the third multiplexer and sent to the second optical connector and / or the first optical connector through the third optical switching switch and the third optical connector.

[0018] In another possible implementation, the first optical component, the second optical component, and the third optical component have the same structure. In this manner, only one module needs to be used in one system, which reduces the development cost of the optical components.

[0022] In order to make the objectives, technical solutions and advantages of the present application clearer, the following describes the embodiments of the present application with reference to the accompanying drawings. It is clear that the described embodiments are only some, but not all, of the embodiments of the present application. With the emergence of new application scenarios, those with ordinary skills in the art may know that the technical solutions provided in the embodiments of the present application can also be applied to similar technical problems.

[0023] In the present specification, claims, and accompanying drawings, terms such as "first," "second," and the like are intended to distinguish between similar objects, but do not necessarily indicate a particular order or sequence. It is understood that data used in such a manner may be interchanged in appropriate circumstances, whereby the embodiments described herein may be performed in other orders than those shown or described herein. In addition, the terms "include," "contain," and any other variations are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or device that includes a series of steps or modules is not necessarily limited to those steps or modules explicitly recited, but may include other steps or modules that are not explicitly recited or that are inherent to such a process, method, system, product, or device. The names or numbers of steps in this application do not imply that the steps in a method procedure must be performed in the temporal / logical sequence indicated by those names or numbers. Based on the technical objective to be achieved, the execution sequence of steps in the named or numbered procedures can be changed, so long as the same or similar technical effect can be achieved. The division into units in this application is a logical division. In actual applications, there may be other division patterns. For example, multiple units may be combined or integrated into another system, or some functions may be ignored or not performed. In addition, the shown or discussed mutual couplings or direct couplings or communication connections may be implemented through some interfaces. The indirect couplings or communication connections between the units may be in electronic form or another similar form. This is not limited in this application.In addition, the units or sub-units described as separate parts may or may not be physically separate, may or may not be a physical unit, or may be distributed into multiple circuit units, some or all of which may be selected according to actual requirements to achieve the objectives of the solution of the present application.

[0024] With the development of communication technology, the requirements for the capacity of routing and switching devices are also increasing. Current switching technologies are usually related to electrical switching systems and optical switching systems. Electrical switching systems are based on packet switching, which can realize switching delays at the microsecond level, and are the mainstream solution for realizing high-speed switching with fine granularity. Optical switching systems are based on optical wavelength or optical link switching, and are currently capable of realizing switching in milliseconds to seconds. Optical switching systems have large bandwidth but low speed.

[0025] Currently, the system architecture of the electrical switching system and the optical switching system has several possible implementations: In the electrical switching full interconnection architecture shown in FIG. 1, the service nodes are directly connected to each other to realize high-speed switching communication between the multiple service nodes; In the electrical switching star interconnection architecture shown in FIG. 2, the multiple service nodes are in an indirect switching connection state through some centralized switching nodes to realize high-speed switching communication between the multiple service nodes; However, after the number of channels in the electrical switching system shown in FIG. 1 and FIG. 2 is determined, future bandwidth expansion can only be performed by increasing the single channel speed, and the improvement of the single channel speed is limited. Therefore, there is a problem that the room for increasing the bandwidth is limited. In the optical switching star interconnection architecture shown in FIG. 3, the multiple service nodes are in an indirect switching connection state through some centralized switching nodes to realize high-speed switching communication between the multiple service nodes. In the optical switching system, the bandwidth can be increased according to the service requirements, but in the switching star interconnection architecture, the overall optical link loss is large due to the loss of N*N optical switches and multiple traversals of the backplane of the service node. Therefore, there is an urgent need for optical components that can increase the bandwidth and reduce the optical link loss according to the service requirements.

[0026] To solve the above problems, an embodiment of the present application provides an optical component 400, as shown in Fig. 4. The optical component 400 includes a service processing module 401, an optical / electrical conversion module 402, a multiplexer 403, an optical switching switch 404, an optical receiving module 405, and an optical connector 406.

[0027] Based on the aforementioned optical component 400, when the optical component 400 serves as a transmission end, the service processing module 401 is configured to process service data in the communication to generate an electrical signal. The optical / electrical conversion module 402 is configured to modulate the service data carried in the electrical signal to an optical source to generate a corresponding optical signal. It can be understood that the optical / electrical conversion module 402 receives an electrical signal, and the optical signal is generated by using an optical source generator. The optical source generator can be integrated into the optical component 400 or can exist separately from the optical component 400. In addition, the optical source generator can generate a multi-wavelength optical source, so that the optical / electrical converter 402 can modulate different service data to different wavelengths to generate different optical signals. The multiplexer 403 can multiplex the optical signals of different wavelengths to generate one optical signal (i.e., a first optical signal), and transmit the optical signal to the optical switching switch 404. The optical switching switch 404 selects a corresponding port to output the optical signal to the optical connector 406. The optical connector 406 is connected to an optical connector of a next-hop optical component (i.e., a service node) via an optical fiber. The optical connector 406 then transmits the optical signal to the next-hop service node via an optical fiber. In this embodiment, the optical component 400 is directly connected to the next-hop optical component.

[0028] Based on the aforementioned optical component 400, when the optical component 400 serves as a receiving end, the optical connector 406 receives a second optical signal transmitted by the optical component of the previous hop (i.e., a service node), and then the optical connector 406 forwards the second optical signal to the optical receiving module 405. The optical receiving module 405 then outputs the second optical signal from a corresponding port, performs demultiplexing to generate a multi-wavelength optical signal, and transmits the multi-wavelength optical signal to the optical / electrical conversion module 402. The optical / electrical conversion module 402 then demodulates the multi-wavelength optical signal to generate a corresponding electrical signal, and transmits the electrical signal to the service processing module 401.

[0029] Based on the optical component 400 shown in FIG. 4, the optical switching switch 404 may be a 1*N optical switching switch, and a diagram of a possible implementation of the optical switching switch 404 may be shown in FIG. 5. It may be understood that the optical switching switch 404 may also be an N*N optical switching switch, and a diagram of a possible implementation of the optical switching switch 404 may be shown in FIG. 6. In this embodiment, the value of N is related to the quantity of service nodes in the optical switching complete interconnect system in which the optical component 400 is used, and the value of N is equal to or greater than the quantity of service nodes in the optical switching complete interconnect system minus 1. For example, if there are a total of six service nodes including the optical component 400 in the optical switching complete interconnect system, the value of N is equal to or greater than five. In addition, the optical switching switch may be an optical switching switch implemented based on micro electro mechanical system (MEMS) technology, or a liquid crystal on silicon-based wavelength selective switch (LCOS-based WSS).

[0030] In this embodiment, in order to realize a response speed for optical switching, the response time of the optical switching switch can be designed to be within a nanosecond level. The specific implementation of the optical switching switch is not limited in this specification.

[0031] Based on the optical component 400 shown in FIG. 4, the optical receiver module 405 may be an arrayed waveguide grating router (AWGR), and a diagram of a possible implementation of the optical receiver module 405 may be shown in FIG. 7. In addition, the optical receiver module 405 may also include a demultiplexer and an N*1 optical switching switch, and a diagram of a possible implementation of the optical receiver module 405 may be shown in FIG. 8. In this embodiment, the value of N is related to the quantity of service nodes in the optical switching complete interconnection system in which the optical component 400 is used, and the value of N is equal to or greater than the quantity of service nodes in the optical switching complete interconnection system minus 1. In addition, the optical switching switch may be an optical switching switch implemented based on micro electro mechanical system (MEMS) technology, or a liquid crystal on silicon-based wavelength selective switch (LCOS-based WSS).

[0032] In this embodiment, in order to realize a response speed for optical switching, the response time of the optical switching switch can be designed to be within a nanosecond level. The specific implementation of the optical switching switch is not limited in this specification.

[0033] Based on the optical component 400 shown in Fig. 4, the quantity of the optical / electrical conversion modules 402 can be set to at least one. However, in a preferred solution, there can be one optical / electrical conversion module 402. It can be understood that there can be two optical / electrical conversion modules 402, and a diagram of a possible implementation of the optical / electrical conversion module 402 can be shown in Fig. 9.

[0034] In this application, a preferred solution of the optical component 400 can be shown in Fig. 10. The optical component 400 includes a service processing module 401, an optical / electrical conversion module 402, a demultiplexer 403, a 1*N optical switching switch 404, an AWGR 405, an optical connector 406, and a light source 407.

[0035] Based on the above solution of the optical component 400, an embodiment of the present application provides an optical switching complete interconnection system 100, as shown in Fig. 11. The optical switching complete interconnection system 100 includes N optical components 400, and the optical components 400 have the structures described in Fig. 4 to Fig. 10. The N optical components 400 serve as service nodes, and any two of the optical components 400 are directly connected to each other. In an exemplary solution, as shown in Fig. 11, the optical component 1 communicates with the optical component 2, and the specific implementation process is as follows:

[0036] When the optical component 1 serves as a transmission end, the service processing module in the optical component 1 is configured to process service data in the communication to generate an electrical signal. The optical / electrical conversion module in the optical component 1 is configured to modulate the service data carried in the electrical signal to the light source to generate a corresponding optical signal. The optical / electrical conversion module in the optical component 1 then outputs the optical signal to the multiplexer in the optical component 1. The multiplexer in the optical component 1 may multiplex the optical signals of different wavelengths to generate one optical signal and transmit the optical signal to the optical switching switch in the optical component 1. The optical switching switch in the optical component 1 selects a corresponding port to output the optical signal to the optical connector in the optical component 1. The optical connector is connected to the optical connector of the optical component 2 via an optical fiber. Therefore, the optical connector in the optical component 1 transmits the optical signal to the optical connector of the optical component 2 via the optical fiber. The optical connector of the optical component 2 receives the optical signal transmitted by the optical component 1, and then the optical connector of the optical component 2 transfers the optical signal to the optical receiving module of the optical component 2. The optical receiving module of the optical component 2 then outputs the optical signals from corresponding ports, performs demultiplexing to generate a multi-wavelength optical signal, and then sends the multi-wavelength optical signal to the optical / electrical conversion module of the optical component 2. The optical / electrical conversion module of the optical component 2 then demodulates the multi-wavelength optical signal to generate a corresponding electrical signal, and sends the electrical signal to the service processing module of the optical component 2.

[0037] In this embodiment, the optical components in the optical switching complete interconnect system 100 may have the same structure or may have different structures, which is not particularly limited in this specification, as long as the functions of the optical switching complete interconnect system 100 can be implemented.

The optical switching system may further have the possible implementation shown in FIG. 14. In this optical switching system, at least one optical component serving as a service node is shown in FIG. 6, and another optical component serving as a service node may have the structure of an existing optical component. This is not particularly limited in this specification. In this optical switching system, the optical component shown in FIG. 6, as a switching node in the whole optical switching system, can implement direct communication between the optical component shown in FIG. 6 and the service node directly connected to the optical component shown in FIG. 6. The service nodes directly connected to the optical component shown in FIG. 6 communicate with each other indirectly by using the optical component shown in FIG. 6. 14, when optical component 2 communicates with optical component 3, optical switching needs to be performed by using optical component 1. However, direct communication can be performed between optical component 1 and optical component 2, or between optical component 1 and optical component 3.
