of high-quality digitized video and two channels of user
selectable multi-protocol data on one multimode optical
fiber using WDM technology. The available data channels
are RS485 (2 or 4 wire), RS422, RS232 and Manchester.
Data rates up to 115 kbs are supported.

Designed to be completely transparent to all camera and
monitor manufacturers, this system requires no field
adjustments at installation or additional maintenance
thereafter. Diagnostic indicators provide a quick visual
indication of system status.
