Dear friend! You can refer to the following screenshot:
The transmit optical power of the LOUT is the sum of the optical power received by the filter module from the RC port and the RM2 port. But here we add numbers in mW, not numbers in dBm. The value obtained after the addition is converted by using the function 10 x Log (N) to reach the value in dBm. The input power of the RC port is the main channel power – VOA attenuation + EDFA gain. Of course, the insertion loss of each interface is also considered.

Hello, The following figure shows the threshold range of the input optical power of the main channel of the DAPXF board.
Hope it help you! Thanks |
