Functions of the TWC and RWC boards on BWG 320G

1

The TWC board is applied in DWDM optical terminals and optical regenerator devices, and is located at the transmit end. The RWC board is applied in DWDM optical terminals and optical regenerator devices, and is located at the receive end.
The functions of the TWC and RWC boards on BWS 320G are as follows:
1. The TWC boards convert optical signals sent from the SDH devices to the wavelengths required by the WDM system by O/E/O conversions. Different TWC boards convert optical signals of different wavelengths. 2. The RWC board transmits optical signals to the SDH devices. It chooses 1310 nm or 1550 nm based on the SDH wavelengths.

Ports for connecting cables on the SCA boards of BWS 320G
Optical port RI on the front panel of SCA boards is an input interface for external optical signals in the OptiX BWS 320G system. The input interface receives signals in the primary channel and OSC sent by the remote OptiX BWS 320G system. TO is an output interface for external optical signals in the OptiX BWS 320G system. The output interface sends multiplexed signals in the primary channel and OSC at the local station to the downstream station.

Signal flow of SC2 boards for OptiX BWS 320G
The optical signals input to the RM1 and RM2 ports of the SC2 board are sent from the RM port of the SCA board. The optical signals output from the TM1 and TM2 ports of the SC2 board are sent to the TM port of the SCA board.
