V.35 Fiber Optic Modem
Model:LNK-2707
►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
V.35 fiber optic Modem is a kind of communication equipment to transmit one channel of V.35 data over a pair of fibers. It uses ASIC chip, adopts modular structure inside, integrates the functions of coding, decoding, information insertion, and alarm switchover. Therefore its circuit is simple, structure is compact and power consumption is low. It is widely used in the occasions that require high reliability and complete auxiliary functions.
►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
