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

Model: Article Number: 21-216

The 21-216 is an electro-optical interface converter between electrical G.703 Codir. 64kbps, balanced, interface and C37.94, N times 64kbps fiber optic interface.


The 21-216 can be used to extend the reach of balanced G.703 interface up to 2km allowing for cost effective transmission without electromagnetic interference and signal degradation. The 21-216 works with any channel selection in the IEE C37.94 data format and can be easily configured.
The 21-216 Fiber Optic G.703 Codir – IEEE C37.94 converter from Fibersystem is intended for connecting tele protection equipment to telecom multiplexers at substations. The 21-216 converter can also be used to directly interconnect protection equipment and multiplexers to use the IEEE C37.94 standard to interconnect with equipment that only support G.703 interfaces.

 

IEEE C37.94

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.
