E1 Fiber Optical Modem is a point to point of high capability Terminal with capacity of 30/120/240 or 480 voice channels. This Terminal offers one channel of asynchronous date channels except 2MBIT/S channels which compatible with ITU-T/G.703.It can be used as relay communications device of LAN, especially adapt to base station of mobile radio communication network to use as optical fiber transmission Terminal and hired equipment. It is small in size and has very light weight. The exterior frame is very compact and looks well. Possess characters of easy installation and adjustment free, high quality of transmission and high reliability of working.
