Glass or plastic fibre should be used for the optical ports. BFOC2.5 is the recommended inter-
face to use (BFOC2.5 is the same as ST connectors). ST connectors are used with the optical
power as specified in standard, please see the Installation and commissioning manual.
For the galvanic interface RS485, use terminated network according to EIA Standard RS-485.
The modem contact for the cable is Phoenix MSTB2.5/6-ST-5.08 1757051.
