Further Product Information

The FOM-485 is an asynchronous miniature fibre optic modem that transmits RS-485 signals over fibre optic cables. The FOM-485 is used in utility applications where there is a need to connect the main controller to a remote terminal unit (RTU). The FOM-485 allows connection of up to 32 RTUs to a single host, at a wide range of data rates up to 115.2 kbps, at typical distances up to 40 km (25 miles) over single mode fibre. The FOM-485 supports full duplex transmission over 4-wire or half duplex over 2-wire cables. It supports diagnostic capabilities complying with the ITU V.54 standard. The modem has six LED indicators to display the status of the modem: TD, RD, DCD, RTS, TEST, and ERR.

Long distance connection to remote terminal units
