DESCRIPTION
The FSW A/B Protection Switch is a continuation of Multidyne’s Fiber Optic Switch (FSW) system. The A/B switch module
may be installed in any VAM system chassis and used in conjunction with your other FSW and VAM modules.
The A/B Switch module provides automatic or manual switching between two fiber lines. When a loss of optical signal is
detected, it will switch to the alternate path in less than 8 msec. The switch is typically used at the receiving end to switch a
transmission to a spare fiber. Upon detecting a signal loss, the switch will automatically switch to a known good fiber. The switching
threshold is set at a low power level to maximize the optical power budget available in the user's network.
The dual optical monitors allow the user to know immediately if the alternate fiber has lost its optical signal. The switch is
latching, so it will retain its state during a loss of electrical power. An internal microcontroller ensures that the switch does not switch to
the opposite state on a power-up.
A manual switch on the front panel allows the user to force the optical switch to either the A or B position or allow it to operate
automatically by monitoring the input fibers. The manual switch has a locking toggle to prevent accidental switching. All of the status
indicators are also available as relay contact closures on the rear power connector.
