VLM-210 synchronous RS449/RS530/V.35 Fiber Optic Modem Description:
The VLM-210 fiber optic modem is designed to provide fiber connection for communication equipment with RS-449, RS-530, or V.35 Interface. Capable of transmitting synchronous data with external clock at speeds from 1 Kbps up to 2.048 Mbps, the optic modem can also be set to transmit asynchronous data at speeds from DC up to 64 Kbps. In synchronous mode, the VLM-210 optic modem encodes the data with the clock pulse, received from the RS-449 / RS-530 / V.35 interface, into serial data stream and sends out to the optic transmitter. In asynchronous mode which has no external clock signal, the modem encodes the data with its internal clock.
