Fiber Optic  Modem

Fiber Optic Modem

The FOM100 is a small, inexpensive fiber optic transmitter/receiver. It features a complete RS-232 port as well as high speed TTL/ RS-422/ RS-423 data transmit and receive. It is capable of data rates from DC to 5M baud. A pair of these units allow most RS-232C cable links to be replaced and extended with a duplex fiber optic cable. The normal 50-foot RS-232 limit may be extended to 1.2 miles (2 km). Fiber optic data communications provide complete EMI / RFI rejection, isolation, elimination of ground loops, and reduced error rates. Data security is enhanced by almost nonexistent electromagnetic emissions. A unique multipoint capability allows local area networks to be formed with the isolation and data security of a fiber optic highway.
