Fiber Optical Converter G.703-C37.94 E1 820nm Multimode
The 21-219 Fiber Optic IEEE C37.94 – G.703 E1 Converter extends distance and provides galvanic isolation between teleprotection equipment and the telecom network in substation environments. Its two independent IEEE C37.94 ports can be used for network redundancy or cross-redundancy in dual installations, ensuring high system reliability.
The converter also works seamlessly with the 21-216 Fiber Optic IEEE C37.94 – G.703 64 kbps Codirectional Converter, making it ideal when teleprotection devices lack C37.94 interfaces or when SDH/PDH networks mix E1 G.703 and 64 kbps G.703 ports across sites.
Functioning as an electro-optical multiplexer, the 21-219 maps two IEEE C37.94 optical ports into the standard G.703/704 E1 frame, enabling full SDH/PDH multiplexing and de-multiplexing. Synchronization is sourced either from the E1 network port or an internal 2048 kbps PDH-compliant clock, allowing use over leased lines with electrical E1 modems such as SHDSL.

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.
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...
