Fiber Optical Converter G.703-C37.94 E1 820nm Multimode
21-219 is an electro optical multiplexer between one G.703/704 E1 and two IEEE C37.94 (C3794) optical ports. The two IEEE ports are fully mapped into G.703 (G703) standard frame structure of the E1 port, allowing for further SDH/ PDH multiplexing and de-multiplexing.
21-219 derives it 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.
Product Description
- Two independent IEEE C37.94 fiber optical connections over a single E1
- Standards compliant for power substation installations i.e ABB
- 19″ mounting with only 200mm depth
- Single power supply range from 48VDC to 230VAC
The 21-219, Fiber optic IEEE C37.94 – G.703 E1 converter is intended to extend distance and galvanically isolate the teleprotection equipment for substation’s connection to telecom network.
The two independent IEEE C37.94 ports can be used for redundancy in the network or as a cross redundancy in dual installations.
The 21-219 Fiber optic IEEE C37.94 – G.703 multiplexer can also be used in combination with the 21-216 Fiber optic IEEE C37.94 – G.703 64 kbps Codirectional Converter, for instance when the Teleprotection equipment lack IEEE C37.94 ports or when the intermediate SDH/PDH network offers a mixture of E1 G.703 ports and 64 kbps G.703 ports on different sites.
