Standard
The 21-219, Fiber optic converter IEEE C37.94 - G.703 E1 is intended to extend distance and galvanic isolate the teleprotection equipment for substations connection to telecom network. The 21-219 is an electro optical multiplexer between one G.703 E1 and two IEEE C37.94 optical ports. The two IEEE ports are fully mapped into the G.703 standard frame structure of the E1 port, allowing for further SDH/PDH multiplexing and de-multiplexing. 21-219 derives its synchronization from the network port (E1) or from an internal 2048Kbps PDH compliant clock enabling it to be used in leased line applications using electrical E1 modems such as SHDSL and alike.
