Fiber Transmission Products

Bi-directional Data Transmitter/Receiver

Overview

The data series fiber transmission products support optical
transmission of bi-directional data up to 4 channels through one fiber
either in multi-mode or single-mode. Adjustment and maintenance
free, these modules are designed to support data interface.

A cost-effective single unit design, this product is well-suited for in
field configuration and also accommodates installation and system
growth while delivering long operating distances of up to 60 Km.
Featuring robust construction well suited for harsh environments the
unit is available in both rack mount and wall mount configuration.
Plug-and-Play design ensures ease of installation requiring no
electrical or optical adjustments.
