Fiber Optical Converter G.703 Codir C37.94 SM
The 21-216 Fiber Optic G.703 Codirectional – IEEE C37.94 Converter is an electro-optical interface converter between G.703 Codir. 64 kbps (balanced) and IEEE C37.94 N×64 kbps optical interfaces. It extends the reach of balanced G.703 connections up to 2 km, ensuring interference-free, cost-effective transmission without signal degradation. The unit supports all IEEE C37.94 channel configurations and is easy to set up.
The 21-216 is designed to connect teleprotection equipment to telecom multiplexers in substations. It can also directly interconnect protection devices when one or both units lack optical interfaces. Overall, it enables equipment using the IEEE C37.94 standard to interoperate with devices that only support G.703 interfaces.

Fiber Optical Extender 80-120km
Fibersystem 21-223 SM/SM Extender (converter) is intended to extend optical reach for low speed data signal into long haul distances. Using a 21-223 the optical short reach signals can be sent without the need for additional and expensive communication systems normally found in long haul communications. When combined with the other products in Fibersystems teleprotection communication product line this converter allows a...
Fo converter IEEE C37.94 and E1 over Synchronous Ethernet (SyncE)
SyncE is an electro-optical converter between two IEEE C37.94 optical ports and/or G.703/704 E1 and synchronous Ethernet and reverse. Both channels are transparently converted into UDP packets and back. Standards compliant for power substation installation.
