Commodity name: HJ-A2001C (1~8 channels)

The HJ-A2001C telephone optical terminal is a point-to-point transmission device developed based on large-scale programmable logic devices, achieving 100M line-rate Ethernet data channel and telephone hybrid multiplexing and transmission.

The device features comprehensive alarm and monitoring functions, high integration, low power consumption, stable performance, and ease of use.

The device is widely used in public security systems, banking systems, highways, telecommunications, mobile, and Unicom communication networks.

All interface technical parameters comply with relevant international or domestic standards;
The device adopts three-level overcurrent and overvoltage lightning protection (very important, as the user lines are laid outdoors), passing ITU-T K.20 lightning surge, power induction test, and power contact test. After circuit surge release, it can automatically recover;
Ethernet interface is adaptive, supports auto-negotiation mode, and operates in full-duplex/half-duplex;
Equipped with Ethernet loopback prevention function (when an optical line loopback occurs, Ethernet data will not be looped back, effectively preventing Ethernet network paralysis caused by Ethernet loopback);
Device power supply is DC5V or AC220V;
Strong anti-interference ability, stable performance, and complete functions;
Comprehensive network management functions, real-time monitoring of various device operating statuses (optional);
Desktop design
