Description

Technical Field

[0001] This application relates to the field of optical communication, and more particularly to an optical device, an optical switching fully interconnect system, and a communication system. Background Technology

[0002] With the development of communication technology, the demand for the capacity of routing and switching equipment is constantly increasing. Current switching technologies typically include electrical switching systems and optical switching systems. Electrical switching systems, based on packet switching, can achieve microsecond-level switching latency and are the mainstream solution for fine-grained, high-speed switching. Optical switching systems are based on optical wavelengths or optical links, currently achieving millisecond-to-second switching latency; they have larger bandwidth but slower speeds.

[0003] Currently, there are several possible implementation methods for the system architecture of electrical switching systems and optical switching systems: such as Figure 1 In the electrically switched fully interconnected architecture shown, each service node is directly connected to the others, thereby enabling fast switching communication between multiple service nodes, such as... Figure 2 In the illustrated star topology of the electrical switching network, multiple service nodes are indirectly connected through several centralized switching nodes to achieve fast communication between them. However, in situations such as... Figure 1 and Figure 2 In the electrical switching system shown, once the number of channels is determined, future bandwidth expansion can only be achieved by increasing the rate of each single channel. However, the increase in single-channel rate is limited, thus limiting the potential for bandwidth expansion. Figure 3 In the optical switching star interconnect architecture shown, multiple service nodes are indirectly connected through several centralized switching nodes to achieve fast switching communication between multiple service nodes. Although bandwidth can be increased according to service requirements in an optical switching system, the star interconnect architecture suffers from significant overall optical link loss due to N*N optical switching losses and four backplane traversals.

[0004] Therefore, there is an urgent need for an optical device that can increase bandwidth and reduce optical link loss according to business needs. Summary of the Invention

[0005] This application provides an optical device, an optical switching interconnect system, and a communication system to reduce backplane loss of optical signals between optical devices and switching nodes.

[0006] In a first aspect, this application provides an optical device, specifically comprising: a service processing module, a photoelectric conversion module, a multiplexer, an optical switching switch, an optical receiving module, and an optical connector; wherein, when the optical device acts as a transmitter, a first electrical signal generated by the service processing module is converted into a first optical signal by the photoelectric conversion module, and the first optical signal is multiplexed by the multiplexer, the optical switching switch, and the optical connector and output to the next hop optical device; when the optical device acts as a receiver, the optical connector receives a second optical signal output by the optical connector of the previous hop optical device, and performs wavelength division by the optical receiving module and outputs it to the photoelectric conversion module, and the second optical signal is converted into a second electrical signal by the photoelectric conversion module and output to the service processing module.

[0007] In this embodiment, the optical device integrates an optical switching switch, enabling the optical device to directly exchange services with other optical devices, thereby reducing backplane loss of optical signals between the optical device and the switching node.

[0008] In one possible implementation, the optical switch is a 1*N optical switch, where N is a positive integer greater than or equal to 2. This can further reduce fiber loss of the optical signal during the switching process.

[0009] In another possible implementation, the number of photoelectric conversion modules is one. This reduces the deployment cost of optical devices.

[0010] In another possible implementation, the optical receiving module is an arrayed waveguide grating router (AWGR); or, the optical receiving module includes a demultiplexer and an N*1 optical switching switch, where N is a positive integer greater than or equal to 2. This increases the number of possible schemes for optical devices to achieve optical receiving functionality.

[0011] In another possible implementation, the optical switching switch is either an optical switching switch based on microelectromechanical system (MEMS) technology or a wavelength selective switch (LCOS-based WSS) based on liquid crystal on silicon technology. This increases the possibilities for implementing the optical switching switch.

[0014] In this embodiment, the optical device in the optical switching full interconnect system integrates an optical switching switch, thereby forming a system architecture in which the optical devices in the optical switching full interconnect system are directly connected to each other, enabling direct service exchange between the optical devices, thereby reducing the backplane loss of optical signals between the optical devices and the switching nodes.

[0015] In one possible implementation, the first optical switch is a 1*M optical switch, where M is a positive integer greater than or equal to N-1; the second optical switch is a 1*M optical switch, where M is a positive integer greater than or equal to N-1.

[0016] In another possible implementation, the optically switched fully interconnected system further includes a third optical device, with the first, second, and third optical devices directly interconnected in pairs. The third optical device includes a third service processing module, a third photoelectric 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 device is used to generate a third optical signal through the third photoelectric conversion module. The third optical signal is then multiplexed by the third multiplexer, and transmitted to the second optical connector and / or the first optical connector through the third optical switching switch and the third optical connector.

[0017] In another possible implementation, the first optical device, the second optical device, and the third optical device have the same structure. This allows only one module to be used in a system, thereby saving on the development costs of optical devices.

[0018] In another possible implementation, the first optical receiving module is an arrayed waveguide grating router (AWGR); or, the first optical receiving module includes a demultiplexer and an M*1 optical switching switch; the second optical receiving module is an arrayed waveguide grating router (AWGR); or, the second optical receiving module includes a demultiplexer and an M*1 optical switching switch, wherein M is a positive integer greater than or equal to N-1.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application are described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Those skilled in the art will understand that with the emergence of new application scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0035] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or modules is not necessarily limited to those explicitly listed, but may include other steps or modules not explicitly listed or inherent to such processes, methods, products, or devices. The naming or numbering of steps appearing in this application does not imply that the steps in the method flow must be performed in the chronological / logical order indicated by the naming or numbering. The execution order of named or numbered process steps can be changed according to the desired technical purpose, as long as the same or similar technical effect is achieved. The division of units in this application is a logical division. In practical applications, there may be other division methods. For example, multiple units may be combined or integrated into another system, or some features may be ignored or not executed. In addition, the shown or discussed mutual coupling, direct coupling, or communication connection may be through some interface, and the indirect coupling or communication connection between units may be electrical or other similar forms, none of which are limited in this application. Furthermore, the units or sub-units described as separate components may or may not be physically separated, may or may not be physical units, or may be distributed among multiple circuit units. Some or all of the units can be selected to achieve the purpose of the solution in this application according to actual needs.

[0036] With the development of communication technology, the demand for the capacity of routing and switching equipment is constantly increasing. Current switching technologies typically include electrical switching systems and optical switching systems. Electrical switching systems, based on packet switching, can achieve microsecond-level switching latency and are the mainstream solution for fine-grained, high-speed switching. Optical switching systems are based on optical wavelengths or optical links, currently achieving millisecond-to-second switching latency; they have larger bandwidth but slower speeds.

[0037] Currently, there are several possible implementation methods for the system architecture of electrical switching systems and optical switching systems: such as Figure 1 In the electrically switched fully interconnected architecture shown, each service node is directly connected to the others, thereby enabling fast switching communication between multiple service nodes, such as... Figure 2 In the illustrated star topology of the electrical switching network, multiple service nodes are indirectly connected through several centralized switching nodes to achieve fast communication between them. However, in situations such as... Figure 1 and Figure 2In the electrical switching system shown, once the number of channels is determined, future bandwidth expansion can only be achieved by increasing the rate of each single channel. However, the increase in single-channel rate is limited, thus limiting the potential for bandwidth expansion. Figure 3 In the optical switching star interconnect architecture shown, multiple service nodes are indirectly connected through several centralized switching nodes to achieve fast switching communication between them. While bandwidth can be increased according to service requirements in an optical switching system, the star interconnect architecture suffers from significant optical link loss due to N*N optical switching losses and multiple traversals of the backplane from service nodes. Therefore, there is an urgent need for an optical device that can both increase bandwidth and reduce optical link loss according to service requirements.

[0038] To address the aforementioned problems, embodiments of this application provide, as follows: Figure 4 The optical device 400 shown includes a service processing module 401, a photoelectric conversion module 402, a multiplexer 403, an optical switching switch 404, an optical receiving module 405, and an optical connector 406.

[0039] Based on the aforementioned optical device 400, when the optical device 400 acts as a transmitter, the service processing module 401 processes the service data in the communication to generate an electrical signal; the photoelectric conversion module 402 modulates the service data carried by the electrical signal onto a light source to generate a corresponding optical signal. It can be understood that the light source generator receives the data from the photoelectric conversion device 402, and this light source generator can be integrated into the optical device 400 or exist independently of the optical device 400. Simultaneously, the light source generator can generate multiple wavelengths of light, allowing the photoelectric conversion device 402 to modulate different service data onto different wavelengths to generate different optical signals. The multiplexer 403 can combine optical signals of different wavelengths to generate a single optical signal (i.e., the first optical signal) and transmit it to the optical switching switch 404. The optical switching switch 404 selects the appropriate port to output the optical signal to the optical connector 406. The optical connector 406 is connected to the optical connector of the next-hop optical device (i.e., the service node) via optical fiber, thus the optical connector 406 transmits the optical signal to the next-hop service node via optical fiber. In this embodiment, the optical device 400 is directly connected to the next-hop optical device.

[0040] Based on the aforementioned optical device 400, when the optical device 400 acts as a receiver, the optical connector 406 receives the second optical signal sent by the previous hop optical device (i.e., the service node); then the optical connector 406 forwards the second optical signal to the optical receiving module 405; then the optical receiving module 405 outputs the second optical signal from the corresponding port and performs wavelength division to generate multiple wavelength optical signals, and then sends the multiple wavelength optical signals to the optoelectronic conversion module 402; then the optoelectronic conversion module 402 demodulates the multiple optical signals to generate corresponding electrical signals and sends them to the service processing module 401.

[0041] Based on the above Figure 4 The optical device 400 shown can include an optical switching switch 404, which can be a 1*N optical switching switch. A possible implementation schematic is shown below. Figure 5 As shown. It can be understood that the optical switching shape 404 can also be an N*N optical switching switch, and a possible implementation diagram is shown below. Figure 6 As shown. In this embodiment, the value of N is related to the number of service nodes in the optical switching interconnect system in which the optical device 400 is applied, and its value is greater than or equal to the number of service nodes in the optical switching interconnect system minus 1. For example, if there are a total of 6 service nodes in the optical switching interconnect system, including the optical device 400, then the value of N is greater than or equal to 5. Meanwhile, the optical switching switch can be an optical switching switch implemented based on microelectromechanical system (MEMS) technology or a wavelength selective switch (LCOS-based WSS) implemented based on liquid crystal on silicon (LCOS) technology.

[0042] In this embodiment, to achieve a fast response speed for optical switching, the response time of the optical switching switch can be designed to be within the nanosecond range. The specific implementation method of the optical switching switch is not limited here.

[0043] Based on the above Figure 4 The optical device 400 shown includes an optical receiver module 405, which can be an arrayed waveguide grating router (AWGR). A possible implementation of this router is illustrated in the diagram below. Figure 7 As shown. The optical receiver module 405 may also include a wavelength division multiplexer and an N*1 optical switching switch, as illustrated in the schematic diagram of one possible implementation. Figure 8As shown. In this embodiment, the value of N is related to the number of service nodes in the optical switching full interconnect system in which the optical device 400 is applied, and its value is greater than or equal to the number of service nodes in the optical switching full interconnect system minus 1. Meanwhile, the optical switching switch can be an optical switching switch implemented based on microelectromechanical system (MEMS) technology or a wavelength selective switch (LCOS-based WSS) implemented based on liquid crystal on silicon technology.

[0044] In this embodiment, to achieve a fast response speed for optical switching, the response time of the optical switching switch can be designed to be within the nanosecond range. The specific implementation method of the optical switching switch is not limited here.

[0045] Based on the above Figure 4 The optical device 400 shown includes at least one photoelectric conversion module 402. However, in a preferred embodiment, the number of photoelectric conversion modules 402 is one. It is understood that the number of photoelectric conversion modules 402 can also be two, and a possible implementation diagram is shown below. Figure 9 As shown.

[0046] In this application, the preferred embodiment of the optical device 400 can be as follows: Figure 10 As shown, it includes a service processing module 401, a photoelectric 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.

[0047] Based on the above-mentioned optical device 400, such as Figure 11 As shown, this application embodiment provides an optical switching fully interconnect system 100, wherein the optical switching fully interconnect system 100 includes N optical devices 400, wherein the optical devices 400 have the above-described...

Figure 11 As shown, optical device 1 and optical device 2 communicate with each other, and the specific implementation process is as follows:

[0048] When optical device 1 is used as a transmitter, the service processing module in optical device 1 is used to process the service data in the communication to generate an electrical signal; the photoelectric conversion module in optical device 1 is used to modulate the service data carried by the electrical signal onto the light source to generate a corresponding optical signal; the photoelectric conversion module in optical device 1 then outputs the optical signal to the multiplexer in optical device 1, which can combine optical signals of different wavelengths to generate a single optical signal and transmit it to the optical switching switch in optical device 1; the optical switching switch in optical device 1 selects the corresponding port to output the optical signal to the optical connector in optical device 1; wherein, the optical connector is connected to the optical connector of optical device 2 through an optical fiber, so the optical connector in optical device 1 transmits the optical signal to the optical connector of optical device 2 through the optical fiber. The optical connector of optical device 2 receives the optical signal sent by optical device 1; then the optical connector of optical device 2 forwards the optical signal to the optical receiving module of optical device 2; then the optical receiving module of optical device 2 outputs the optical signal from the corresponding port and performs wavelength division to generate multiple wavelength optical signals, and then sends the multiple wavelength optical signals to the photoelectric conversion module of optical device 2; then the photoelectric conversion module of optical device 2 demodulates the multiple optical signals to generate corresponding electrical signals and sends them to the service processing module of optical device 2.
