Optical Switch Module Description
The optical switch module is used for switching the input of an EDFA module from
a primary signal to a backup or secondary signal. The switch operates in the 1550
nm wavelength range since its application is high power/long haul systems that
employ EDFAs.
The switch has two operating modes: manual and automatic. In automatic mode,
the switch can be triggered by a loss of light. The loss of light activation triggers
the switch when the light level drops below the threshold value set by the operator.
In manual mode, the switch can be triggered through the Local Control Module
(LCM).
The modules can be mounted in slots 3 through 6 and 8 through 10 on the optical
interface board in the housing lid.

different on the two sides.
