Product function: E1 fiber modem is to modulate E1 signal to single or multi-mode
fiber. Suit for transmit additional management data channel in
different fibers.The fiber for transmit data can be used to monitor
and control local and remote devices, and no collision will occur. ENVIRONMENT REQUIREMENT: Environment The device operate temperature range wide, can work normally and
stable in different environments. Operate temperature: 0C~50C Relative humidity: 95% (no condensation) No causticity and impregnant gas, no rising dust, and no strong
magnetic field disturbing. Power supply Use module power supply as following for option, working voltage
range wide, good anti-disturb and isolation, work stable. DC-48V: voltage range -36V~-72V AC220V: voltage range 175V~265V power consumption <5w E1 interface match G.703 a. Rate: 2.048Mbps. b. Code: HDB3 c. E1 Impedance: 75ohm (unbalance) and 120ohm(balance). Unbalance match with coaxial adapter, can match 75-2 coaxial wire.
Balance match with balance adapter, can connect with twisted-pair
wire. d. Interface character: match G.703. e. Connector: BNC(75ohm), RJ45(120ohm). f. Jitter tolerance: fine than G.742 and G.823. g. Clock: synchronize input E1 signal.
