UN series

Optical Data Transmission System

As a system of optical links this product line enables the user to establish optical connections between various different computers via RS232 (V24). This version consist of an opto-electronic transceiver within a standard plug.
Within this product line, a powerful and easy to use plug & play system can be installed.
Two different connectors are available: one for plastic fibres and one for glass fibres. When using plastic fibre, only a sharp knife is needed for installation. Units arranged for glass fibres are equipped with standard ST-series fibre optic connectors. The user can attach the fibre without opening the plug.
The product line UN-Series allows a low cost, robust and reliable link.
No external power supply is required. The power for the transmit and receive circuitry is drawn from the port of the connected equipment.
