Question
The input optical power of an OAU101 board in a network is -19dBm, and the output power needs to reach 1dBm. Due to the long distance, a DCM (D) module is connected between the TDC and RDC of the board, and the attenuation is 5.5 dB, then in order to meet the requirements, the gain of the board should be set on the network management?
