Description

Technical Field

[0001] The present application relates to the field of wavelength division network technology, and in particular to a client-side module, a multiplexer, a wavelength division transmission device, and a communication system. Background Art

[0002] In a wavelength division multiplexing (WDM) network, a bidirectional repeater can typically implement relaying in two directions, for example, relaying from line-side module 1 to line-side module 2, or relaying from line-side module 2 to line-side module 1.

[0003] Some highly integrated muxponders can have two line-side modules on a single board. Establishing a connection between the two line-side modules enables the muxponder to function as a bidirectional relay. However, the two line-side modules of a muxponder are typically connected via a serial deserializer (SerDes), a switch, or external cables. The use of a SerDes or switch to connect the two line-side modules increases the power consumption of the muxponder, while the external cables take up considerable space within the device. Summary of the Invention

[0038] The technical solution in this application will be described below with reference to the accompanying drawings.

[0039] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0040] In various embodiments of this application, the terms "first," "second," and so on are merely used to indicate that multiple objects are distinct. For example, the terms "first pin group" and "second pin group" are merely used to indicate different pin groups. These terms should not affect the pin groups themselves or their number. The terms "first," "second," and so on should not limit the embodiments of this application in any way.

[0041] The terms "include", "comprising", "having" and variations thereof mean "including but not limited to", unless specifically emphasized otherwise.

[0042] In a wavelength division network, there are two types of boards, one is a repeater and the other is a multiplexer. The service transmission path of the repeater can be as follows: Figure 1 As shown, the service transmission path of the multiplexer can be as follows Figure 2As shown. For a repeater, a line-side module can be used to convert an optical signal into an electrical signal, and then convert the electrical signal into an optical signal after amplification and processing to achieve long-distance transmission. For a multiplexing transponder, a line-side module can be connected to multiple client-side modules to multiplex the client-side modules to the line side for forwarding. The client-side module can convert the optical signal into an electrical signal, and the line-side module can further convert the electrical signal into an optical signal for transmission. The line-side module can be a module connected to the trunk network side, and the client-side module can be a module connected to the user side, which is the external interface of the optical transport network.

[0043] For some highly integrated multiplexer transponders, two line-side modules can be set up on one board at the same time, such as Figure 3 As shown in FIG, this multiplexer can have the function of bidirectional relay. However, there is usually no connection between the two line side modules of this multiplexer. The highly integrated multiplexer can be as follows Figure 4 As shown, if a bidirectional relay function is to be implemented between two line-side modules, a connection relationship must be established between the two line-side modules to implement signal forwarding between the two line-side modules.

[0044] If a connection is to be established between two line-side modules, one approach is to directly add a serial deserializer (serdes) to the line-side module. However, this approach will increase the power consumption of the multiplexer and increase the chip design complexity of the line-side module.

[0045] Another way is to add a switch in the multiplexer, such as Figure 5 As shown. For example, the switch can be connected to client-side module 4, client-side module 5, line-side module 1, and line-side module 2. The switch can be used to establish connections between different modules at different times. When the switch is turned toward the client-side module, it can establish connections between line-side module 1 and client-side module 4, and between line-side module 2 and client-side module 5. When the switch is turned toward line-side module 2, it can establish a connection between line-side module 1 and line-side module 2. While adding a switching switch to a muxponder can reduce the design complexity of the line-side chip, the need for a new switch chip still increases the power consumption and cost of the muxponder.

[0046] Another approach is to use the space available for the client-side module to add a cable module. This module is then connected to the cable modules of the two line-side modules using an external cable installed on the board. However, this approach has the disadvantages of large external cables taking up space and high costs.

[0047] Therefore, the embodiment of the present application provides a highly integrated multiplexing transponder that supports a bidirectional relay function, can reduce the power consumption of the multiplexing transponder, and has a smaller size.

[0048] Figure 6 and Figure 7 The three-dimensional structural diagram and the schematic block diagram of the structure of a client-side module 200 provided in an embodiment of the present application are respectively provided. The client-side module 200 can be applied to a multiplexing transponder, and the client-side module 200 can be a module connected to a client-side device. The present application does not limit the name of the client-side module 200. The client-side module 200 can be a pluggable device (small form-factor pluggable, SFP) in a miniaturized form, for example, a quad small form-factor pluggable, QSFP, or a double-density QSFP (quad small form-factor pluggable-doubledensity, QSFP-DD), etc. Figure 6 and Figure 7 As shown, the client side module 200 may include a housing 201, a module circuit board 203, a module structure 202 and a connector 204 ( Figure 6 (not shown). The housing 201 can also be referred to as the cage of the client-side module 200. The connector 204 can be disposed within the housing 201 and fixedly connected to the housing 201. The module circuit board 203 can be a printed circuit board and disposed within a module structure 202. The module structure 202 can be connected to the housing 201 and, for example, may include components such as snaps for inserting and removing the module from the housing 201. When the module structure 202 is disposed within the housing 201, the module circuit board 203 can be electrically connected to the connector 204.

[0049] The client-side module 200 can be integrated onto a single board, such as a PCB, or the housing 201 can be disposed on a single board. Multiple client-side modules 200 can be mounted on a single board, enabling signal forwarding between multiple client-side modules 200. The various components of the client-side module 200 are described in detail below with reference to the accompanying drawings.

[0050] For example, the module circuit board 203 may include a pin group 1 and a pin group 2, wherein the pin group 1 may also be referred to as a first pin group, and the pin group 2 may also be referred to as a second pin group. The pin group 1 and the pin group 2 may each include multiple pins, and the pins in the pin group 1 may be connected to the pins in the pin group 2, such as Figure 7 As shown by the double-headed arrow between pin group 1 and pin group 2.

[0051] Figure 8 This is a schematic diagram of the pin connections in a client side module 200 provided in an embodiment of the present application. Figure 8 It can be a connection diagram between the pins on the module circuit board 203 of the client side module 200, and the Figure 8 It can be a schematic diagram of the connection between the pins of the client side module 200 when viewed from the upper side of the module circuit board 203. The pin group 1 may include Figure 8 At least part of the pins in the left column of pins, for example, can include pins TX1, TX3, RX4 and RX2 for signal transmission or sending in the left column of pins, and pin group 2 can include Figure 8 At least some of the pins in the right column of pins may include, for example, pins TX5, TX7, RX8, and RX6 in the right column for signal transmission or sending. The TX pin may be a pin for transmitting data or signals, the RX pin may be a pin for receiving data or signals, and 1, 2, 3, ..., 8 may be the numbers of the respective pins.

[0052] It should be noted that the Figure 8 The figure schematically illustrates only the pins included when viewed from the top of the module circuit board 203, rather than all the pins on the module circuit board 203. The module circuit board 203 may also include the pins included when viewed from the bottom of the module circuit board 203. Accordingly, the pin group 1 and the pin group 2 may also include the pins included when viewed from the bottom of the module circuit board 203. For example, the pin group 1 may also include pins TX2, TX4, RX1, and RX3 for signal transmission or reception, and the pin group 2 may also include pins TX6, TX8, RX5, and RX7 for signal transmission or reception. In addition, in the embodiment of the present application, the pin group in the left column of the module circuit board 203 is exemplarily recorded as pin group 1, and the pins in the right column are recorded as pin group 2. The pins in the right column can also be pin group 1, and the pins in the left column can be pin group 2. Alternatively, any 4 pins among the pins used for signal sending and any 4 pins among the pins used for signal receiving in the module circuit board 203 can form the pin group 1, and the remaining pins for signal sending and the pins for signal receiving can form the pin group 2. The present application does not limit the specific pins in pin group 1 and pin group 2.

[0053] In some embodiments, the numbers of the interconnected pins in pin group 1 and pin group 2 may be different. For example, both pin group 1 and pin group 2 may include multiple pins, and the multiple pins of pin group 1 may be connected one-to-one with the multiple pins of pin group 2, such as Figure 8In the example shown, pin TX1 in pin group 1 can be connected to RX8 in pin group 2, pin TX3 in pin group 1 can be connected to RX6 in pin group 2, pin RX4 in pin group 1 can be connected to TX5 in pin group 2, and pin RX2 in pin group 1 can be connected to TX7 in pin group 2. The TX and RX pins can each include a positive electrode (p) and a negative electrode (n), and the connection between the positive and negative electrodes can be positive to positive, negative to negative, or positive to negative. For example, pin TX1 can include a positive electrode TX1p and a negative electrode TX1n, and pin RX8 can include RX8p and RX8n. When pin TX1 is connected to pin RX8, the connection can be TX1n to RX8n, TX1p to RX8p, or TX1p to RX8n, or TX1n to RX8p.

[0054] When the numbers of the two interconnected pins in pin group 1 and pin group 2 on the module circuit board 203 are the same, for example, when TX1 is connected to RX1, the pin connection method is a loopback connection, the pin positions are the same, and the signal sending and receiving positions are the same; when the numbers of the interconnected pins in pin group 1 and pin group 2 are different, the pin connection method is a cross connection, and the positions of the two interconnected pins are different, which can transmit the signal from one position to another, thereby realizing signal forwarding on the module circuit board 203.

[0055] It should be noted that the above example only schematically illustrates the connection method between the multiple pins of pin group 1 and the multiple pins of pin group 2 on the module circuit board 203. TX1, TX3, RX4, RX2, TX5, TX7, RX8 and RX6 can be pins arranged on the same surface of the module circuit board. Figure 8 In the pin connection method shown, TX1 is connected to RX8. TX1 can also be connected to RX6, or to RX5 or RX7 on the other side of the module circuit board. The connections of the remaining pins are similar. This application does not limit the specific connection method of the pins. Figure 8 The pins shown are standard commercial pins. When the pins on the module circuit board 203 are custom pins, the two interconnected pins in pin group 1 and pin group 2 can also have the same number. It is only necessary that the two interconnected pins in pin group 1 and pin group 2 can be used to forward signals. In addition, the TX pin can be a pin for signal transmission or a pin for signal reception. Similarly, the RX pin can be a pin for signal reception or a pin for signal transmission. The TX pin is shown as connected to the RX pin, but the two interconnected pins can also be TX pins or RX pins. It is only necessary that the two interconnected pins can be used for both signal transmission and reception.

[0056] In the embodiment provided in the present application, in the client-side module, pin group 1 and pin group 2 of the module circuit board are connected to each other, which can realize signal forwarding inside the module. Therefore, when the client-side module is used in a multiplexing repeater, the client-side module can forward the signal transmitted by a line-side module to other client-side modules, and forward it to another line-side module by other client-side modules, thereby realizing the connection between the two line-side modules, thereby enabling the multiplexing repeater to support and realize the two-way relay function, and can reduce the power consumption of the multiplexing repeater.

[0057] As an example, pin group 1 and pin group 2 can be directly connected via a connection line 205, such as Figure 7 As shown, the connecting wires 205 can be directly provided on the module circuit board 203. In this implementation, the multiple pins of pin group 1 and the multiple pins of pin group 2 can be interconnected using connecting wires 205. The connection between pin group 1 and pin group 2 via connecting wires 205 within the module circuit board 203 is relatively simple, can reduce the power consumption of the client-side module and the muxponder, and has low production costs.

[0058] As another example, pin group 1 and pin group 2 may also be connected via the switch module 206. Figure 9 As shown. For example, the client-side module 200 may also include an optoelectronic conversion module, which can be used to implement mutual conversion between optoelectronic signals. After the line-side module transmits the electrical signal to the client-side module 200, the optoelectronic conversion module can convert the electrical signal into an optical signal for transmission. Alternatively, the optoelectronic conversion module can convert the optical signal into an electrical signal for transmission to the line-side module. The optoelectronic conversion module can also be connected to pin group 1 and pin group 2. The switch module can be used to connect pin group 1 to the optoelectronic conversion module, or to connect pin group 1 to pin group 2, at different times.

[0059] As described above, pin group 1 and pin group 2 can respectively include multiple pins, and the multiple pins in pin group 1 can be connected one-to-one with the multiple pins in pin group 2. When pin group 1 and pin group 2 are connected through a switch module, each group of interconnected pins can be connected through a switch module respectively, and multiple pins in the same pin group can be isolated from each other, or in other words, there is no connection relationship between multiple pins in the same pin group.

[0060] As another example, pin group 1 and pin group 2 may also be connected via an external cable 207, such as Figure 10As shown, the external cable is a connecting wire outside the module circuit board 203. For example, the module circuit board 203 may include a connecting wire 207 on the outside. The connecting wire 207 may be welded to the outside of the module structure 202, that is, welded to the outside of the accommodation space enclosed by the module structure 202. The connecting wire 207 may be connected to the pins in pin group 1 and pin group 2, respectively, to transmit signals sent by the pins in pin group 1 to the pins in pin group 2, or transmit signals sent by the pins in pin group 2 to the pins in pin group 1.

[0061] In this example, pin group 1 and pin group 2 may each include multiple pins. The multiple pins in pin group 1 and pin group 2 may be interconnected via connecting wires external to module circuit board 203. Multiple pins in the same pin group may not be interconnected. For example, the module structure 202 may include multiple connecting wires 207 on the outside, and two interconnected pins in pin group 1 and pin group 2 may be interconnected via different connecting wires 207 external to module circuit board 203.

[0062] The connector 204 of the client-side module 200 may also include multiple pins. The multiple pins of the connector 204 may be used to connect to the multiple pins of the module circuit board 203, and may also be used to connect the client-side module 200 to other client-side modules or line-side modules.

[0063] For example, see Figure 7 、 Figure 9 or Figure 10 For any of the client-side modules shown, the connector 204 may include pin group 3 and pin group 4. Pin group 3 may also be referred to as the third pin group, and pin group 4 may also be referred to as the fourth pin group. Pin group 3 and pin group 4 may each include multiple pins. Pin group 3 may be connected to pin group 1 of the module circuit board 203, as indicated by the double-headed arrow between pin group 1 and pin group 3. Pin group 4 may be connected to pin group 2, as indicated by the double-headed arrow between pin group 2 and pin group 4. When the client-side module 200 is disposed in a multiplexer, pin group 3 may also be connected to a line-side module, and pin group 4 may also be connected to other client-side modules. Furthermore, the connector 204 can transmit the signal sent by the line side module to the module circuit board 203. Since there is a connection between pin group 1 and pin group 2 on the module circuit board 203, the signal can be forwarded on the module circuit board 203, for example, from pin group 1 to pin group 2. Further, pin group 2 can transmit the signal to pin group 4, and from pin group 4 to other client side modules, realizing a two-way relay function.

[0064] In some embodiments, the interconnected pins in pin group 3 and pin group 1 may have the same numbering, and the interconnected pins in pin group 4 and pin group 2 may also have the same numbering. For example, the connector 204 of the client-side module 200 may include pins TX1 to TX8 for signal transmission and pins RX1 to RX8 for signal reception. Pin group 3 may include pins TX1 to TX4 and RX1 to RX4, and pin group 4 may include pins TX5 to TX8 and RX5 to RX8. Pin TX1 in pin group 1 may be connected to pin RX1 in pin group 3, and pin RX8 in pin group 2 may be connected to pin TX8 in pin group 4. The connections for other pins are similar, so that the two interconnected pins on the connector 204 and the module circuit board 203 have the same numbering.

[0065] It should be noted that, similar to the pins on the module circuit board 203, the pin RX on the connector 204 can also be defined as a pin for signal transmission, and the pin TX can also be defined as a pin for signal reception. In this example, the two pins connecting the module circuit board 203 and the connector 204 can also be both RX pins or both TX pins.

[0066] By connecting the pins inside the client-side module, the client-side module can be connected to the line-side module, and the client-side module can be connected to other client-side modules.

[0067] The embodiment of the present application also provides a multiplexing transponder, which may include the above Figures 7 to 10 For any client-side module described above, the structure of the multiplexer can be as follows Figure 11 shown.

[0068] The multiplexer may include a client side module 1 and a client side module 2, a line side module 1 and a line side module 2, wherein the client side module 1 may also be referred to as a first client side module, the client side module 2 may also be referred to as a second client side module, the line side module 1 may also be referred to as a first line side module, the line side module 2 may also be referred to as a second line side module, and the line side module may be a module that interfaces with the line side device. The client side module 1 and the client side module 2 may both be the above Figures 7 to 10 Any of the client side modules described above, and the structure of the client side module 1 can be the same as or different from the structure of the client side module 2. For example, the client side module 1 can be Figure 7 The client side module shown, the client side module 2 can be Figure 9 The client side module shown, or client side module 1 and client side module 2 can also be Figure 7 Client-side module shown.

[0069] In the client-side module 1, the module circuit board 203 of the client-side module 1 may include a pin group 1 and a pin group 2. The pin group 1 may also be referred to as the first pin group of the client-side module 1, and the pin group 2 may also be referred to as the second pin group of the client-side module 1. The pin group 1 may be connected to the pin group 2. Figure 11 The pin group 1 and the pin group 2 shown in FIG are directly connected via the connecting wires on the module circuit board 203. The connection method of the pin group 1 and the pin group 2 can also be as follows: Figure 9 or Figure 10 The connection method shown is not limited in this application. The connector 204 of the client-side module 1 may include a pin group 3 and a pin group 4. Pin group 3 may also be referred to as the third pin group of the client-side module 1, and pin group 4 may also be referred to as the fourth pin group of the client-side module 1. Pin group 3 may be connected to pin group 1, and pin group 4 may be connected to pin group 2, to achieve signal transmission within the client-side module 1, transmitting signals from the connector 204 of the client-side module 1 to the module circuit board 203, or from the module circuit board 203 of the client-side module 1 to the connector 204. The pin group 3 can also be connected to the line side module 1 so that signals can be transmitted between the client side module 1 and the line side module 1. The pin group 4 can also be connected to other client side modules, such as the client side module 2, so that signals can be transmitted between the client side module 1 and the client side module 2, thereby enabling the client side module 1 to forward the signal sent by the line side module 1 to the client side module 2, or enabling the client side module 1 to forward the signal sent by the client side module 1 to the line side module 1.

[0070] In the client-side module 2, the module circuit board 203 of the client-side module 2 may include a pin group 5 and a pin group 6. The pin group 5 may also be referred to as the first pin group of the client-side module 2, and the pin group 6 may also be referred to as the second pin group of the client-side module 2. The pin group 5 may be connected to the pin 6. Figure 11 The pin group 5 and the pin group 6 are directly connected via the connecting wires on the module circuit board 203. The connection method of the pin group 5 and the pin group 6 can also be Figure 9 or Figure 10The connection method shown is shown. The connector 204 of the client-side module 2 may include a pin group 7 and a pin group 8. The pin group 7 may also be referred to as the third pin group of the client-side module 2, and the pin group 8 may also be referred to as the fourth pin group of the client-side module 2. The pin group 7 may be connected to the pin group 5, and the pin group 8 may be connected to the pin group 6, to enable signal transmission within the client-side module 2, transmitting signals from the connector 204 of the client-side module 2 to the module circuit board 203, or from the module circuit board 203 of the client-side module 2 to the connector 204. The pin group 7 may also be connected to the line-side module 2, and the pin group 8 may also be connected to other client-side modules, such as the client-side module 1. The client-side module 1 is connected to the client-side module 2 via pin group 4 and pin group 8. On the basis that the client-side module 1 and the client-side module 2 are respectively connected to the line-side module 1 and the line-side module 2, that is, pin group 3 is connected to the line-side module 1 and pin group 7 is connected to the line-side module 2, a connection can be established between the line-side module 1 and the line-side module 2, thereby enabling the multiplexing repeater to support bidirectional relay, that is, relay in the direction from the line-side module 1 to the line-side module 2, and relay in the direction from the line-side module 2 to the line-side module 1.

[0071] Illustratively, the connector 204 of the client-side module 1 may include pins TX1 to TX8 for signal transmission and pins RX1 to RX8 for signal reception, wherein pins TX1 to TX4 and RX1 to RX4 may be pins in pin group 3 and may be used to connect to the line-side module 1, and pins TX5 to TX8 and RX5 to RX8 may be pins in pin group 4 and may be used to connect to the client-side module 2. Similarly, the connector of the client-side module 2 may also include pins TX1 to TX8 for signal transmission and pins RX1 to RX8 for signal reception, wherein pins TX1 to TX4 and RX1 to RX4 may be pins in pin group 7 and may be used to connect to the line-side module 2, and pins TX5 to TX8 and RX5 to RX8 may be pins in pin group 8 and may be used to connect to the client-side module 1. In other words, pin group 4 of the client-side module 1 may be connected to pin group 8 of the client-side module 2. The pins of the client-side module 1 connected to the client-side module 2 can be numbered the same. For example, the pin TX5 of the client-side module 1 can be connected to the pin RX5 of the client-side module 2, the pin TX6 of the client-side module 1 can be connected to the pin RX6 of the client-side module 2, the pin TX7 of the client-side module 1 can be connected to the pin RX7 of the client-side module 2, the pin TX8 of the client-side module 1 can be connected to the pin RX8 of the client-side module 2, the pin RX5 of the client-side module 1 can be connected to the pin TX5 of the client-side module 2, the pin RX6 of the client-side module 1 can be connected to the pin TX6 of the client-side module 2, the pin RX7 of the client-side module 1 can be connected to the pin TX8 of the client-side module 2, and the pin RX8 of the client-side module 1 can be connected to the pin TX8 of the client-side module 2. The numbers of the two pins connecting the client-side module 1 and the client-side module 2 can also be different. For example, the pin TX5 of the client-side module 1 can be connected to the pin RX6 of the client-side module 2, and the pin RX5 of the client-side module 1 can be connected to the pin TX7 of the client-side module 2, etc. It is only necessary to establish a connection between the client-side module 1 and the client-side module 2 to realize signal transmission.

[0072] It should be noted that, similar to the connection method between the module circuit board 203 and the connector 204, and the pin connection method within the module circuit board 203 described above, when the client-side module 1 and the client-side module 2 are connected, the two interconnected pins can also be TX pins, or can also be RX pins. The TX pin can also be defined as a pin for signal reception, and the RX pin can also be defined as a pin for signal transmission.

[0073] In the prior art, when a client-side module is used in a multiplexing transponder, the client-side module's transmit pins TX1-TX4 and receive pins RX1-RX4 are used to connect to the line-side module, while the client-side module's transmit pins TX5-TX8 and receive pins RX5-RX8 are unused. The embodiments provided in this application establish a connection between the transmit pins TX5-TX8 and receive pins RX5-RX8 of two client-side modules corresponding to different line-side modules, enabling a connection between the two line-side modules and implementing a bidirectional relay function.

[0074] Furthermore, in this multiplexing transponder integrated with two line-side modules, after line-side module 1 transmits a signal to client-side module 1, client-side module 1 can forward the received signal to client-side module 2, which then forwards it to line-side module 2. Alternatively, line-side module 2 can first transmit a signal to client-side module 2, which can then forward the received signal to client-side module 1, which can then forward it to line-side module 1, thereby achieving a bidirectional relay function.

[0075] The line side module 1 and the line side module 2 can be connected to multiple client side modules respectively, and the client side module 1 can be any one of the multiple client side modules connected to the line side module 1, and the client side module 2 can also be any one of the multiple client side modules connected to the line side module 2. For example, see Figure 12 The multiplexer shown.

[0076] The line side module 1 can be connected to four client side modules respectively, for example, it can be connected to client side module 1 and client side modules 3 to 5 respectively. Similarly, the line side module 2 can be connected to four client side modules respectively, for example, it can be connected to client side module 2 and client side modules 6 to 8. The client side module 1 and the client side module 2 can be Figures 7 to 10 Any of the client side modules described above, and client side modules 3 to 8 can be Figures 7 to 10 Any of the client-side modules described may not be. Figure 11 Similar to the described multiplexer, the client-side module 1 can be connected to the client-side module 2 to achieve the connection between the line-side module 1 and the line-side module 2 .

[0077] It should be noted that the multiplexer may also include more than two line side modules, for example, it may also include a line side module 3, the line side module 3 may also be connected to multiple client side modules, and the line side module 3 may also be connected to the line side module 1 and / or the line side module 2. The connection method between the line side module 3 and the line side module 1 and / or the line side module 2 may be similar to the connection method between the line side module 1 and the line side module 2, that is, the line side module 3 may also be connected to at least one Figures 7 to 10 The client side module described above can be connected to the client side module in the line side module 1 and / or the line side module 2. The embodiment of the present application does not limit the number of line side modules included in the multiplexer. In addition, Figure 12 In the multiplexing repeater shown, one line side module is connected to four client side modules. In the embodiment provided in the present application, one line side module can also be connected to two, three or more client side modules. The present application does not limit the number of client side modules connected to the line side module.

One or more muxponders may be integrated on a PCB. The muxponder may also be in the form of an all-in-one device, or may be referred to as a box, where one box may include one or more muxponders.

[0079] The embodiment of the present application also provides a wavelength division transmission device, which may include one or more Figures 11 and 12 Any of the multiplexers described.

[0081] The wavelength division transmission device may also include a control unit and a power supply unit. The control unit may be used to transmit a control signal to one or more service units so that each service unit forwards the client-side service to the line-side service. The power supply unit may be used to supply power to one or more service units.

[0082] The embodiments of the present application also provide a communication system, which may include one or more wavelength division transmission devices as described in the above embodiments, as well as a receiving device and a transmitting device. The receiving device and the transmitting device may be a receiving device and a transmitting device on the client side, or a receiving device and a transmitting device on the line side. The multiplexer in the communication system may provide both receiving and transmitting functions. For example, the multiplexer in the communication system may convert a client-side signal from a client-side transmitting device into a line-side signal and transmit it to a receiving device on the line side, or may convert a line-side signal from a line-side transmitting device into a client-side signal and transmit it to a receiving device on the client side.
