Fiber Optical Converter IEEE C37.94 MM/SM
21-203 is a protocol independent optical-electrical-optical long haul converter link with data integrity control for high reliability. The incoming multimode signal is sampled and packaged in 4B/5B code before transmission on the singlemode interface.
Incoming singlemode signal is decoded and error detected before reassembled and transmitted out the multimode interface. This conversion method offers a better (lower) error rate for low speed signals compared to transparent converters suitable only for high speed signals.
