Introduction
V. 35 Optical Modem can realize long distance data transmission by transmitting N*64k V. 35 signals via fiber, It is a kind of communication equipment to
Transmit one channel of V. 35 data over a pair of fibers.
It uses ASIC chipset, adopts modular structure inside, integrates the functions of coding, decoding, information insertion, and alarm switchover. Therefore its circuit is simple and easy for maintenance, structure is compact and power consumption is low. It is widely used in the occasions that require high reliability and complete auxiliary functions. It can extend data channel of ATM or DDN.

Features
Providing one optical port, supporting point-to-point connection in pairs or connection to E1 fiber optic Modem
Providing one V. 35 port, with the rate of N * 64 Kb/s (N = 1-32), adjustable
Providing three timing modes: Mater timing, tracing V. 35 port, and tracing optical port
Supporting automatic tracing function of remote timeslot bandwidth
Providing auto-sensation between the receive clock and data phase at V. 35 port
Supporting multiple loopback functions and bit error of internal link test function, facilitating engineering commissioning
Providing the remote electrical outage detection function, which can tell whether it is fiber cut or the remote electrical outage
Rich panel display enables the user easy to identify the fault
