Question
At an OLA site, the maximum output optical power of the OAU is 20 dBm. It is used in an 80- wavelength C-band system. 10 waves are actually enabled. There is no spectrum analysis board, and the combined signal needs to be used for commissioning. How much dBm should be adjusted for the output optical power of the OUT port?
Options
- A20 dBm
- B5 dBm
