if the overhead is insufficient. Second, an EDFA driven to saturation will not handle long
streams of either 0 or 1.
When the number of channels running on the fiber is high and the signals are uncorrelated,
the recommended operating mode is “Telco optimised Constant Power”. In this mode, the
EDFA will have a very fast regulation loop that ensures error free operation on other
channels when one or more channels are added/subtracted from the fiber. For this mode,
operation in saturation (full output power) is recommended.
