The V35 Modem is a high-performance V.35 to fiber modem developed by using a dedicated integrated circuit. The V.35 to fiber converter is to modulate a N*64K V.35 data signal directly over single or multi-mode optic fiber for a transmission via optic cable line. At another end of the optic cable, optical signal is demodulated into a V.35 data signal. V.35 interface may be directly connected with the V.35 interfaces of image and data terminals or the WAN ports of MUX, exchanger and router for a dedicated network setup or a LAN connection.
