Fiber optic G.703 Codir-IEEE C37.94 Converter
Article Number: 21-216
- Fiber optic G.703 Codir - IEEE C37.94 Converter
Function
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.
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 Teleprotection and Multiplexer Equipment" describes a fiber optic intra-substation communication links between teleprotection equipment and multiplexers.
G.703 64kbps Codirectional
The ITU-standard "G.703 64kbit/s codirectional interface" describes a galvanic interface commonly used by teleprotection equipment for connection to multiplexers.
Applications
The 21-216 Fiber 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 and multiplexers to use the IEEE C37.94 standard to interconnect with equipment that only support G.703 interfaces.
