Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device and switching device for configuring an optical engine. Background Art

[0002] With the development of network technology, users' demand for network transmission speed is gradually increasing. The current electrical signal transmission is approaching a bottleneck. In order to further improve the network transmission speed, optical signals can be used to partially replace electrical signals for transmission. CPO (Co-packaged Optics or Co-packaging) technology and NPO (Nearpackaged optics) technology came into being.

[0003] In switching devices using CPO or NPO technology, external light sources are usually used to provide optical signals for the switching devices. External light sources can be divided into data pass-through type external light sources and non-data pass-through type external light sources. Among them, data pass-through type external light sources can be divided into at least DR (Data Center Reach) type external light sources and FR (Far Reach) type external light sources. These external light sources can use the same interface type. After the optical signal is introduced into the switching device, it is transmitted to the outside through the processes of splitting and coupling in the optical engine to carry the optical signal data.

[0004] Since the wavelengths of optical signals emitted by non-data direct-type external light sources, DR-type data direct-type external light sources and FR-type data direct-type external light sources are not completely consistent, different configurations of splitters and couplers are required in the optical engine of the switching device. As a result, a switching device can only use one type of external light source after configuration. However, for staff, if they blindly insert the external light source used by the switching device without being sure of the type, the optical signal may not be output and other types of external light sources need to be replaced, which reduces the flexibility of the switching device in using external light sources.

[0041] Here, exemplary embodiments are described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification.

[0042] The present application provides a switching device 100, such as Figure 1-3As shown, it includes a processor 101, one or more interfaces 102, and a light engine 103 corresponding to the interface 102, and the interface 102 is connected to the external light source 200. In the NPO or CPO switching device 100, a circuit board 107 is arranged near the front panel 104, and the processor 101, the optical cable 105 (or the flexible board for transmitting optical signals), the light engine 103, and the logic device 106 for processing and switching electrical signals are arranged on the circuit board 107, wherein the processor 101 is used to realize the configuration of the light engine 103 and other devices.

[0043] Generally speaking, the optical engine 103 is connected to the interface 102 via the optical cable 105 for optical signal input and output, and the cables of the processor 101 and its peripheral circuits (not shown) are led to the logic device 106 for coupling and transmission with the optical transmission signal. Figure 1 This is only an example and does not limit the specific connection relationship between the structures.

[0044] Light engine 103, such as Figure 2 As shown, including:

[0045] First modulation arm 1030;

[0046] The second modulation arm 1031;

[0047] A phase shifter 1032 connected to the first modulation arm 1030, and used for transmitting an electrical signal of data carried in the optical signal transmitted by the first modulation arm 1030;

[0048] An optical splitter 1033, wherein an input end 1033A of the optical splitter 1033 is connected to an optical signal input end of the interface 102, and an output end 1033B of the optical splitter 1033 is connected to the first modulation arm 1030 and the second modulation arm 1031, respectively, for splitting the received optical signal input to the first modulation arm 1030 and the second modulation arm 1031;

[0049] A coupler 1034, wherein an input end 1034A of the coupler 1034 is connected to the first modulation arm 1030 and the second modulation arm 1031 respectively, and a signal output end 1034B of the coupler 1034 is connected to an optical signal output end of the interface 102;

[0050] The first compensator 1035, the input end 1035A of the first compensator 1035 is connected to the processor 101, the output end 1035B of the first compensator 1035 is respectively connected to the splitter 1033 and the coupler 1034, and the processor 101 sets the compensation value of the first compensator 1035 to the splitter 1033 and the coupler 1034 according to the type of external light source obtained from the register 201 of the external light source 200.

[0051] Among them, there is a corresponding relationship between the light engine 103 and the interface 102. When the external light source 200 is plugged into the interface 102, the pin on the circuit board of the external light source 200 connected to the processor 101 of the switching device 100 can detect the presence signal of the external light source 200, so that according to the correspondence between the interface receiving the presence signal and the light engine 103, it is determined that the external light source 200 is plugged into a certain interface 102. One interface 102 can correspond to one light engine 103, or multiple interfaces 102 can correspond to one light engine 103. The actual situation can be set according to the needs of the device, and there is no restriction on this. The presence signal can be a high level or a low level, which can be set according to the actual situation. The external light source 200 can include multiple types, such as non-data direct-through external light sources, DR external light sources, and FR external light sources.

[0052] In the switching device, the optical engine 103 is made of silicon-based waveguides to form the above-mentioned devices, and the silicon-based waveguides have electrical transmission properties and optical transmission properties respectively. Optical signals can be transmitted on the first modulation arm 1030 and the second modulation arm 1031. The phase shifter 1032 set on the first modulation arm 1030 receives the electrical signal of the data transmitted by the logic device, and carries the electrical signal on the optical signal transmitted by the first modulation arm 1030, so as to achieve the purpose of transmitting data through optical signals.

[0053] After the optical signal enters the switching device from the optical signal input end of the interface 102, it is transmitted to the optical engine 103 through the optical cable 105 (or flexible board). The external light source 200 can be divided into an optical signal part and an electrical signal part. The external light source 200, the electrical signal part can include a circuit board 202, a laser 203 and a register 201, and the external light source type of the external light source 200 can be recorded in the register 201. The register 201 can include several register pages (pages), and a register page can include several register bits. Generally speaking, the register 201 can include 256 register pages of 00h-FFh, each register page can include 256 register bits of 0-255, each register bit is 1 byte, and different information is represented by 8 bits of "0" and "1". In the external light source 200, the register 201 and the laser 203 are respectively arranged on the circuit board 202. After the external light source 200 is connected to the interface 102 of the switching device 100, the circuit board 202 is connected to the circuit board 107 in the switching device 100 through the gold finger, so as to supply power to the laser 203 and the register 201 in the external light source 200. Figure 1 The external light source 200 shown is a DR data direct-through type external light source.

[0054] That is to say, in order to identify the type of the external light source of the external light source 200, two register bits, namely the first register bit and the second register bit, can be preset in the register 201. The first register bit is used to identify whether the external light source 200 belongs to a data-through type external light source or a non-data-through type external light source, that is, whether the external light source can transmit an optical signal carrying data to the outside on the basis of providing an optical signal. The second register bit is used to identify whether the external light source belongs to a DR type data-through type external light source or a FR type data-through type external light source, that is, to identify the transmission method of the optical signal data of the external light source.

[0055] Specifically, the first register bit can be located on page 00h or page 01h of register 201. In page 00h and page 01h, the first register bit can be any value from byte 0 to byte 255 in each register page, and can be set according to actual needs. The second register bit can also be located on page 00h, and can be located at any value between byte 0 and byte 255. Preferably, the second register bit can be byte 170 on page 00h. The following is described by taking the external light source 200 as a DR-type data-through external light source as an example. When the processor 101 reads the first register bit, it first determines that the external light source 200 is a data-through external light source, not a non-data-through external light source. Secondly, when the processor 101 reads the second register bit, it can determine whether the external light source 200 is a DR-type or a FR-type. It should be noted that, since the non-data direct-through type external light source does not distinguish whether the transmission category is DR or FR, after determining that the external light source 200 is a non-data direct-through type external light source, the value of the second register bit can no longer be judged. It should be noted that, since one register bit is 1 byte, and 1 byte contains 8 bits, at least one bit is required to indicate the data direct-through type and the non-data direct-through type, and the identification page of the DR class and the FR class needs to occupy at least one bit, therefore, the first register bit and the second register bit can be located on a byte of the same page, or on different bytes of the same page, or on different bytes of different pages, and can be set according to actual needs, without limitation.

[0056] After the optical signal enters the optical engine 103, the first splitting is performed according to the demand. For example, an optical fiber is split into four paths, and each path enters the modulator 1036 of the optical engine 103 for modulation. The above-mentioned first modulation arm 1030, second modulation arm 1031, phase shifter 1032, splitter 1033, coupler 1034 and first compensator 1035 can be packaged as a modulator 1036, or they can be formed separately without being packaged as a whole.

[0057] After the optical signal of the external light source 200 enters the modulator 1036 after being split, first, the optical signal enters the optical splitter 1033, and the optical splitter 1033 splits the input optical signal again in a ratio of one to two. When splitting, the optical splitter 1033 needs to be compensated by the first compensator 1035. The first compensator 1035 has different compensation values ​​according to the type of the external light source 200. The compensation value includes a first compensation value and a second compensation value. The non-data direct-through type external light source and the DR type data direct-through type external light source correspond to the first compensation value, and the FR type data direct-through type external light source corresponds to the second compensation value. In other words, the compensation value of the non-data direct-through type external light source is consistent with the compensation value of the DR type data direct-through type external light source.

[0058] Secondly, during the transmission of the optical signal along the first modulation arm 1030, the phase shifter 1032 receives the electrical signal for transmitting data output by the logic device, adds the electrical signal to the optical signal and outputs it to the first modulation arm 1030. The optical signal transmitted on the second modulation arm 1031 has the same frequency and phase as the optical signal transmitted on the first modulation arm 1030, but no data is added to the optical signal transmitted on the second modulation arm 1031. The power ratio of the optical signal on the first modulation arm 1030 and the second modulation arm 1031 is 1:1, that is, if the power of the optical signal entering the splitter 1033 is 100, the first modulation arm 1030 and the second modulation arm 1031 will each receive 50 optical signals.

[0059] When the optical signals transmitted on the first modulation arm 1030 and the second modulation arm 1031 reach the coupler 1034, they are superimposed into an optical signal with a power of 100. After that, the coupler 1034 splits the light again, and this time the power ratio between the detection output terminal 1034C and the signal output terminal 1034B of the coupler 1034 is 1:99, that is, the detection output terminal 1034C outputs only a very low-power optical signal for detection, while the optical signal power at the signal output terminal 1034B is relatively large for data transmission.

[0060] Since the optical signal is easily affected by temperature during the transmission of the silicon-based waveguide, in order to reduce the influence of temperature on the optical signal transmission, the optical engine 103, such as Figure 3As shown, it also includes a second compensator 1037 and a MPD (Monitor Photo Detector) 1038, wherein the input terminal 1038A of the MPD 1038 is connected to the detection output terminal 1034C of the coupler 1034, the output terminal 1038B of the MPD 1038 is connected to the input terminal 1037A of the second compensator 1037, and the output terminal 1037B of the second compensator 1037 is connected to the first modulation arm 1030 and / or the second modulation arm 1031. It should be noted that the second compensator 1037 is used to compensate for the difference between the first modulation arm 1030 and the second modulation arm 1031. The second compensator 1037 can compensate for the difference between the two by compensating one of the modulation arms. Therefore, the output terminal 1037B of the second compensator 1037 can be selectively connected to one of the modulation arms for compensation, or can be connected to the two modulation arms respectively and select one modulation arm for compensation, etc. There is no limitation to this. Figure 3 The second compensator 1037 is indicated by a dotted line in the figure as being connected to either the first modulation arm 1030 or the second modulation arm 1031 .

[0061] After the optical signal is output from the detection output terminal 1037C of the coupler 1034, the MPD 1038 can detect the output optical signal, determine the optical signal parameters such as the extinction ratio and amplitude of the optical signal, and compensate by outputting a compensation value to the second compensator 1037. The compensation value can be used to adjust the refractive index of the first modulation arm 1030 and the second modulation arm 1031 to change the optical path of the optical signal, etc., so as to adjust the temperature drift.

[0062] In the switching device 100, if it is determined that the temperature drift within a certain range will not affect the transmission of the optical signal, the second compensator 1037 and the MPD 1038 may not be provided, and they may be provided according to actual needs without limitation.

[0063] In addition, since the DR4 data direct-through type external light source 200A and the FR4 data direct-through type external light source 200B process the optical signal for transmitting data differently, such as Figure 4As shown, in the DR4 type data direct external light source 200A, the optical signal for transmitting data is directly connected from the input side to the output side, and in the FR4 type data direct external light source 200B, the optical signal for transmitting data needs to be multiplexed and demultiplexed through the multiplexer / demultiplexer (MUX / DEMUX) 204 after entering from the input side, and then connected to the output side for output. In the FR4 type data direct external light source, since it includes the transmission of 4 wavelengths, on an input layer of the MUX / DEMUX 204, it is necessary to obtain an optical fiber from each wavelength band for multiplexing, and the process of rearranging the optical fibers to meet the input requirements of the MUX / DEMUX 204 can be called rearrangement. If this rearrangement process is implemented in the external light source 200, it will take up a large space.

[0064] In order to simplify the internal structure of the external light source 200 while flexibly adapting to DR4 and FR4 (including non-data direct-through external light sources, DR4 data direct-through external light sources and FR4 data direct-through external light sources), the rearrangement process can be implemented inside the switching device 200, such as in the optical engine 103 or on the optical cable 105 (or a flexible board that implements the corresponding function).

[0065] like Figure 5 , 6 As shown, the optical engine 103 can be divided into two groups according to different wavelengths of FR4 class, each group contains 4 optical fibers, and each optical fiber corresponds to a wavelength, for example, it can be divided into 1271, 1291, 1311 and 1331. Each optical fiber enters four modulators 1036 after 1:4 splitting, and forms an optical signal for transmitting data after passing through the modulator 1036. An optical path rearrangement mechanism 108 for rearrangement is provided on the optical cable 105 (or flexible board) of the switching device 100. The optical path rearrangement mechanism 108 can be implemented by the optical cable 105 or the flexible board, and the optical fiber for transmitting the optical signal can be encapsulated in the flexible board.

[0066] The interface 102 includes a light source input terminal 102A and an optical signal transmission terminal 102B, wherein the optical signal transmission terminal 102B includes an optical signal input terminal for receiving data and an optical signal output terminal for sending data. Each optical signal in the light source input terminal 102A is respectively input into a modulator group of the optical engine 103, and the modulator group includes a plurality of modulators 1036. Each optical signal is split and transmitted to a modulator group for modulation.

[0067] The optical path rearrangement mechanism 108 includes a plurality of optical fiber groups 1080 , wherein an input end 1080A of each optical fiber group 1080 corresponds to a signal output end 1034B in a plurality of modulator groups, and an output end 1080B of each optical fiber group 1080 is connected to an optical signal transmission end 102B included in the interface 102 .

[0068] like Figure 5 , 6 As shown, on the interface 102, the optical signal input terminal 102A may include 8-way light source input, 32-way light signal input for receiving data, and 32-way light signal output for sending data. After the 8-way light source input enters the optical engine 103, it is split 1:4 to form 32-way optical signals, which are loaded with the received electrical signal data through the modulator 1036. Figure 6 For example, the rightmost fiber group includes fibers 1081, 1082, 1083, and 1084. Fiber 1081 corresponds to a modulator in modulator group 1036W, fiber 1082 corresponds to a modulator in modulator group 1036X, fiber 1083 corresponds to a modulator in modulator group 1036Y, and fiber 1084 corresponds to a modulator in modulator group 1036Z. This fiber group 1080 can correspond to an optical signal transmission end 102B of an interface 102 for output.

[0069] In the FR4 type data pass-through external light source, each modulator group corresponds to an optical signal of one wavelength, so an optical signal transmission end 102B can contain optical signals of four wavelengths for sending data. After transmission from the interface 102 to the external light source 200, the external light source does not need to rearrange these optical signals, and can be directly connected to the MUX / DEMUX204 through an optical cable, saving space in the external light source 200.

[0070] Correspondingly, the present application provides a method for configuring a light engine, such as Figure 7 As shown, the switching device applied to the above-mentioned switching device includes:

[0071] S400: If a presence signal of an external light source is detected, determine an interface corresponding to the presence signal and a light engine corresponding to the interface.

[0072] like Figure 1 Switching equipment and external light source shown.

[0073] The interface and the light engine have a corresponding relationship, which can be recorded in the processor of the switching device. After the processor detects the presence signal of the external light source, it determines the identifier of the interface to which the external light source is plugged, and determines the light engine that needs to be configured based on the corresponding relationship between the identifier of the interface and the light engine.

[0074] S401, obtaining the type of the external light source from the register of the external light source.

[0075] Due to the connection between the external light source and the switching device, the circuit board on the switching device and the circuit board in the external light source are electrically connected through gold fingers and the like. The processor can obtain the external light source type of the connected external light source from the register in the external light source. In the register, there are at least two register bits, the first register bit is used to identify whether the external light source is a data direct-through type external light source, and the second register bit is used to identify whether the external light source is a DR type or a FR type. It should be noted that if the first register bit identifies the external light source as a non-data direct-through type external light source, then the second register bit will be considered to be a DR type regardless of its value.

[0076] Among them, the external light source type at least includes a non-data direct-type external light source, a DR type data direct-type external light source and a FR type data direct-type external light source. Optionally, the register includes a first register bit and a second register bit, the first register bit is used to identify that the external light source belongs to a data direct-type external light source or a non-data direct-type external light source, and the second register bit is used to identify that the external light source belongs to a DR type data direct-type external light source or a FR type data direct-type external light source. Optionally, the first register bit is located on page 00h or page 01h. Optionally, the second register bit is the 170th byte on page 00h. Specifically, the setting of the external light source type and the corresponding register bit can be based on demand and is not limited to the above two types.

[0077] S402: Setting a compensation value of a compensator in a corresponding light engine according to the type of the external light source.

[0078] The compensation value includes a first compensation value and a second compensation value.
