Embodiment 1
[0026] This embodiment provides an optical fiber transmission subsystem, its external structure is as follows figure 1 As shown, it includes several service cards 2 of different rates, such as 100M service card, 1.25G service card, 2.5G service card, 10G service card, and a network management board 3; the optical fiber transmission subsystem also includes a device frame , the equipment frame provides a rear panel, a front panel, and N card slots; wherein the network management card 3 needs to occupy a slot, and the service card 2 can choose any one of the slots 1 to N; the existing equipment The value of N is 16, and N can also take different integer values according to actual needs. The optical fiber transmission subsystem adopts a front-mounted monitoring and a rear-mounted outlet mode, and the front panel is provided with a network monitoring interface, an Ethernet interface, an optical fiber interface, and an equipment test port; the rear panel is provided with a power i...
Embodiment 2
[0032] This embodiment provides a transmission method for the optical fiber transmission subsystem described in Embodiment 1, and the method includes the following steps:
[0033] Step 1, the several service cards of different rates respectively receive signals of different rates from different clients;
[0034] Step 2, the several service cards of different rates are all connected to the control bus to realize the communication control between the service cards of different rates and the corresponding rate clients; the communication process between the service cards of different rates and the corresponding rate clients is: The first CDR module receives a signal from the client side, the crossover chip transmits the signal from the first CDR module to the control chip, and the control chip transmits the control signal to the second CDR module, and the second CDR module transmits the signal to the control chip. The signal from the control chip is transmitted to the WDM side for...
