Introduction  

MODEL7305 Optic Fiber Modem is a high-performance optic modem developed by using a dedicated integrated circuit. It is to modulate a N×64K Ethernet 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 an E1 data signal. E1 interface may be directly connected with the E1 interfaces of image and data terminals or the WAN ports of MUX, exchanger and router for a dedicated network setup or a LAN connection.
