● Integrated circuit based on independent intellectual property rights;
● It provides 2 optical interfaces, double optical port 1 + 1 protection (APS), ALS (automatic laser shutdown/reduction) functions: after detecting the optical fiber interruption of the optical path, the optical transmitter has no output power, and can automatically return to normal state after the optical fiber is recovered;
● The ethernet interface rate is 10/100M, full duplex/half duplex adaptive; the 12-channel network is the switch port and can also be divided into VLAN, which can be set as 12-channel logical isolation;
● E1 interface meets the recommendation of G.703 and adopts full digital clock recovery and smooth phase-locked technology;
● When the optical signal is lost, it can detect whether the opposite equipment is powered down or the optical fiber is blocked, and indicate the alarm through the indicator light;
● It has the function of viewing and displaying the working status of remote equipment at the local end;
● 8channel voice telephone; voice telephone port supports FXO port and FXS port, FXO port connects with SPC exchange, FXS port connects with user’s telephone;
● When the optical signal is lost, it can detect whether the opposite equipment is powered down or the optical fiber is blocked, and indicate the alarm through the indicator light;
● It has the function of viewing and displaying the working status of remote equipment at the local end;
● It provides a remote interface loopback function.
● It provides a console management interface for easy installation and opening, and provides network management interface (BNC) for network management monitoring;
● The transmission distance without a relay can reach 2 ~ 120 km;
● Multiple power supply modes: AC220V, dc-48v / DC24 V, etc.; support AC + DC, AC + AC, DC + DC and other dual power backup modes;
● Dc-48v / DC24 V power supply has the function of automatic polarity detection, so it is unnecessary to distinguish the positive and negative poles during installation.
