Two-Channel Serial Optical Repeater up to 8km
The optical repeater transmits serial optical signals over long distances via multi-mode FO cables. It converts serial optical 820 nm signals at Port 1 and Port 2 in the range 300 bit/s - 1.5 Mbit/s to 1300 nm for multimode fiber cables. Both synchronous and asynchronous signals can be connected. Two independent, serial 820 nm inputs with ST connectors are available, which are multiplexed to Port 3. One transmit (Tx) and one receive (Rx) signal is supported (no RTS/CTS handshake signals).
Two devices with an optical 820 nm interface, for example the 7SD52 / 7SD610 line differential protection relay or the RS232/820 nm 7XV5652 converter, can be connected to Ports 1 and 2 via multi-mode FO cables for distances of up to 1.5 km. Signal transmission at Port 3 is achieved via the LC-Duplex connector at wavelengths of 1300 nm for connection of a multi-mode FO cable. For Port 3 there are two options for a max. of 4 km (1300 nm) and 8 km (1300 nm) optical fiber lengths. The device can be connected to all battery voltages and AC supply sources. Loops can be activated for Ports 1 / 2 for commissioning purposes, so that the input signals can be mirrored at the port in question.
