The F-OS optical switch is used for system redundancy and backup. With the use of an optical switch, a redundant signal can be routed to an active path in the event of a fault. The F-OS optical switch features low insertion loss which is typically 0.6dB. The unit offers three types of switching 1x2, 2x1, or 2x2. The remote switching ability is very useful for managed systems. A front panel LCD provides system status and provides a means of programing the switch. The F-OS can also be dynamically configured for CADM and OXC systems.
