Product Profile of Fibre-optic Modem
Orion Electronics supplies Fibre-Optic Modem. Dataforth LDM 85 is a small, inexpensive fibre-optic transmitter/receiver completely powered by the host RS-232 port. The enclosure for the LDM 85 is a conductive shell, which greatly reduces RF radiation and susceptibility. The rugged metal enclosure is small enough to mount on the back panel of typical computer equipment. A pair of this unit allows most RS-232 cable links to be replaced and extended with a duplex fibre-optic cable. The normal 50 feet RS-232 limit may be extended to 2.0 km. Fibre optic data communication provides complete EMI/RFI rejection, isolation, elimination of ground loops and reduced error rates. Data security is enhanced by almost non-existent electromagnetic emission. RS-232 connection is through male/female EIA25 pin connector. Fibre-optic connection is through SMA [905] or ST connector. LDM 85 is equivalent to 3 wires RS232 full-duplex circuit. LEDs are provided for diagnostics.
