Field Description
Output Power
Setting The output power setting is used to activate the output power control mode on FEC transponders and force
the transponder to regulate the optical output power. An improper setting of the transponder output power
level could affect either of the following:
•The equalization of the channel downstream from the optical line, the optical channel S/N in fiber, and
at the end of the optical line.
•The optical channel power at the end of the optical line.
