V23875-T3261-C110
The V23875-T3261-C110 is an optical triplexer
component designed for full-duplex digital
communication over a single fiber with an additional
analog video receiver. The single fiber concept saves
overall system costs by eliminating one fiber,
allowing for doubling of capacity without installing
new fibers, and simplifying fiber management.
