RAD Data Communications, Inc.48-Channel Local Fiber Optic MultiplexerFLM-3
Description
FEATURES
FLM-3 is a Time Division Multiplexer, enabling up to 48 asynchronous terminals to be multiplexed onto a single cable, in point-to-point or ring-type applications. Each channel can be used for either a data signal or a control signal. FLM-3 contains a built-in modem which drives the high speed multiplexed data over a fiber optic cable up to a distance of 4 km (2.5 miles).
Multiplexing is performed by sampling all subchannels at a rate much higher than the data rate of each subchannel, and then interleaving the samples into a frame. Then, FLM-3 transmits the frame onto the main channel. At the other end, the samples are recombined to form the original bits. The high sampling rate of FLM-3 enables transmission of async data and control signals with low distortion and without delay.
FLM-3 has four 50-pin female connectors, located on the rear panel, each supporting 12 channels. Connection of individual units can be provided by using octopus-type cables. These cables split the cable which extends from the 50-pin connector, into 12 individual cables.
Local and remote digital loopback capability, provided through front panel switches and LEDs, enables complete monitoring of the local and remote activities from either end of the system.
