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 Ethernet data signal. Ethernet  interface may be directly connected with the Ethernet  interfaces of image and data terminals or the WAN ports of MUX, exchanger and router for a dedicated network setup or a LAN connection.
1. Rate N×64Kbit/s (N=1~32)
2. Support the loopback of local analog/digital interface
3. Support remote loopback function
4. Support pseudo-random code test function
5. 120km trunking -free transmission distance for single-mode optic fiber
6. Capable to be communicated with FE1 Fiber Modem
7. Available with complete line detection and alarm indications
8. Available with independent structure and 19-inch Rack-mountable structure Rack-mountable structure can be inserted with 16 modules
9. AC 220V and DC –48V inputs may be selected for fiber optic modems of both structure
10. For Rack-mountable fiber optic modems, dual power supply heat backup is provided to ensure a high operating reliability
