Overview
E1 Optical Fiber Modem, which is used for modulating a framing or non-framing E1 data signal directly into single-mode 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 framing or non-framing E1 data signal. E1 interface may be directly connected with the E1 interfaces of image and data terminals or the WAN ports of MUX, switch and router for a dedicated network setup or a LAN connection.

Features
In accordance with ITU-T G. 703 G. 704 standards
Framing or non-framing mode in option
Support local loop and remote loop
Support pseudo-random code test function
Capable to be communicated with V. 35 fiber modem
