Optical Switch Operating Parameters

This section is a reference for the operating parameters of the optical switch. The
optical switch is configured through the Status Monitor/Local Control Module in
the node. Refer to the Model GS7000 Hub/Node Status Monitor/Local Control Module
Installation and Configuration Guide, part number OL-29937-01, for complete
instructions on configuring the optical switch.

[1] Hysteresis Amplitude (default 1.0 dB) is the value above which the input
optical power must rise for the switch to begin sequence to return to the primary
switch position. Hysteresis Amplitude is a user configurable parameter.
