(10-Bit) Transmitter/Receiver

Overview

The video and data series fiber transmission products support optical
transmission of 10-Bit PCM coded video (up to 8 channels) with bi­directional audio up to two channels through one fiber either in multi­mode or single-mode for convenience and flexibility. Adjustment and
maintenance free, these modules are universally compatible with
major CCTV camera manufacturers and support audio interface.

The unit’s unique modular design for in-field configuration also
accommodates installation and system growth and delivers long
operating distances of up to 60Km. Featuring robust construction
well suited for harsh environments the unit is available in wall-mount
configuration. Plug-and-Play design ensures ease of installation
requiring no electrical or optical adjustments.
