Introduction
MODEL7302 FE1 Fiber Modem is a high-performance E1 fiber
into a framing or non-framing E1 data signal. E1 interface may be
optic modem developed by using a dedicated integrated circuit. It is
directly connected with the E1 interfaces of image and data terminals
to modulate a framing or non-framing E1 data signal directly into
or the WAN ports of MUX, exchanger and router for a dedicated
single- or multi-mode optic fiber for a transmission via optic cable
network setup or a LAN connection.
line. At another end of the optic cable, optical signal is demodulated
