The OS-3131 is a fiber optic switch that can be controlled remotely or
through a front panel switch. The optical path through the units is purely
optical, so there is no optical to electrical to optical conversion. There
is no electrical loss or electrical bandwidth limit on the fiber optic path.
The optical path can be select via a front panel switch or via contact
closure input. In event of loss of power, the unit has a fail safe mode that
forces the switch to revert to port A.
Common applications for this device are optical routing,
system bypass, network cut off switch, and fiber optic testing. The OS-3131
control can be daisy chained to switch multiple optical connections. For two
OS-3131 mounted in a single housing, order the OS-3231. If you
need a latching version, use model OS-2131
