Definition
Composite output
power
P
OUT/C
Sum of the power present in all the individual
wavelengths at the output of the amplifier.
Composite gain
Gc
Amount of gain the composite input of the power to
the amplifier will receive.
Constant Power Mode (Default)
Constant power mode is the default operating mode for broadcast EDFAs.
The EDFAs also have an attenuation feature with a 3 dB attenuation range. For
example, for the 17 dBm amplifier, an attenuation of 0.0 dB to 3.0 dB in 0.1 dB steps
can be set to achieve the output powers of 17.0 dBm to 14.0 dBm in 0.1dBm steps,
respectively. See the following table.

GS-EDFA-BCST-17-SA
Default: 17 dBm
Optional: 14.0 dBm to 16.9 dBm in 0.1
dB steps
GS-EDFA-BCST-20-SA
Default: 20 dBm
Optional: 17.0 dBm to 19.9 dBm in 0.1
dB steps
GS-EDFA-BCST-22-SA
Default: 22 dBm
Optional: 19.0 dBm to 21.9 dBm in 0.1
dB steps
Constant Gain Mode (Optional)
Broadcast EDFAs can optionally be operated in constant gain mode. The mode is
set through the LCM. The following table shows the operating conditions in
constant gain mode and an example of input and output ranges for a 16 channel
system.
