Fiber optic G.703 Codir-IEEE C37.94 Converter

Fiber optic interface according to standard “IEEE C37.94-2002, IEEEStandard for N times 64 Kilobit per Second Optical Fiber Interfaces between Tele protection and Multiplexer Equipment” describes a fiber optic intra-substation communication links between tele protection equipment and multiplexers.

G.703 64kbps Codirectional

The ITU-standard “G.703 64kbit/s codirectional interface” describes a galvanic interface commonly used by tele protection equipment for connection to multiplexers.

Function
The 21-216 is an electro-optical interface converter between electrical
G.703 Codir. 64Kbps (balanced) interface and IEEE C37.94, N times 64Kbps
optical interface.
The 21-216 can be used to extend the reach of balanced G.703 interfaces upto 2km allowing for a cost effective transmission without electromag netic interference and signal degradation.
The 21-216 works with any channel selection in the IEEE C37.94 data format and can be easily configured.
Usage
The 21-216 Fibre optic G.703 Codir. – IEEE C37.94 converter from Fibersystem is intended for connecting teleprotection equipment to telecom multiplexers at substations. The 21-216 converter can also be used to directly interconnect protection equipment where one or both equipments lack optical interfaces. The 21-216 generally allows protection equipment and multiplexers to use the IEEE C37.94 standard to interconnect with equipment that only support G.703 interfaces.
