The 21-203 is a protocol independent optical-electrical-optical long haul converter link with data integrity control for high reliability.
This conversion method offers a better (lower) error rate for low speed signals compared to transparent converters suitable only for high speed signals.
The 21-203 MM/SM converter is intended to extend optical reach for any low speed optical data signal into the long haul distances.
Using a 21-203 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 for a very cost effective solution.
The 21-203 is particularly useful in differential line protection setups where dedicated fiber is available thus eliminating the need for multiplexers for the teleprotection traffic.
The 21-203 is compatible with the standards based IEEE C37.94 optical interface for teleprotection equipment and its protocol independence makes ideal for interoperation with any teleprotection equipment suppliers products
