The two IEEE ports are fully mapped into G.704 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.

AI Overview BETA

The Fibersystem 21-219 converts one G.703/704 E1 connection into two IEEE C37.94 fibre-optic ports. Its two optical ports map into the E1’s G.704 frame structure, allowing further SDH or PDH multiplexing. For leased-line applications using electrical E1 modems such as SHDSL, it can synchronise from its internal 2048 kbps PDH-compliant clock or the network E1 port.

Standards-compliant for power substation installations
Multimode fibre options: 50/125 µm or 62.5/125 µm, with ST connectors
Typical fibre link distance: 0–2 km
Single power supply supports DC or AC input
Weight: 3 kg
