E1(Framed E1) to Fiber Optic Modem

Introduction:
MODEL7302 FE1 Fiber Modem is a high-performance E1 fiber optic modem developed by using a dedicated integrated circuit. It is to modulate a framing or non-framing E1 data signal directly into 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 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, exchanger and router for a dedicated network setup or a LAN connection. 
Features:
1. Conforms to all relevant ITU series standards( ITU-T G.703 G.704 G.823)
2. Framing or non-framing mode in option
3. E1 time slot in arbitrary option
4. Balanced 120Ω/non-balanced 75Ω interfaces automatic
5. Support the loop back of local analog/digital interface
6. Support remote loop back function (valid on under framing mode)
7. Support pseudo-random code test function, providing convenience for the test of optic fiber line status
8. 120km trunking -free transmission distance for single-mode optic fiber
9. Capable to be communicated with V.35 fiber modem
10. Available with complete line detection and alarm indications
11. Available with independent structure and 19-inch frame-mounted structure (frame-mounted structure can be inserted with 16 modules);
12. AC 220V and DC –48V inputs may be selected for fiber optic modems of both structures;
13. For frame-mounted fiber optic modems, dual power supply heat backup is provided to ensure a Receiving level：0~-43db
