iv. Use local Video diagnostic equipment to confirm quality of input video
overlay optical signal.
v. Use local Video diagnostic equipment to confirm quality of amplified
video overlay optical signal using the monitor port of the unit.
vi. Increase optical output power of the unit (affects all ports) to boost sig-
nal to overcome loss.
vii. Decrease the optical output power of the unit (affects all ports) to reduce
the detrimental effects of SBS. (Quality of SBS suppression is deter-
mined by the optical CATV video transmitter that is input to the EDFA
unit)
viii. If Input optical power and wavelength in specification and optical output
is enabled and the unit is not in low power mode yet there is an output
power minor or major alarm or pump diode minor or major alarm it may
indicate internal failure of the unit.
c. 1310/1490nm Voice/Data Service issues (CWDM units only)
i. If there are issues with 1310nm/1490nm Voice/Data CWDM ports then
check the loss of the OSC-OS port routings with the EDFA disabled. If
the loss is
