Industry background

A large number of monitoring points are distributed in outdoor environments such as roads, tunnels, and factories. The transmission distance of coaxial cables is limited and susceptible to electromagnetic interference. Network cables exceeding 90 meters are unstable. Optical fiber transformation has become a mainstream choice for security projects.

Customer pain points

  • Points are scattered and power supply is difficult, requiring long-distance transmission and centralized management;
  • Outdoor lines are bitten by rats, struck by lightning, and cut during construction, resulting in high failure rates;
  • PTZ control requires a reverse data channel;
  • Existing analog cameras need to be reused and accessed.

Solution architecture

The front-end uses 1-4 channels of video optical transceivers (including 1 channel of reverse 485 control), and the aggregation layer uses 16/32-channel rack-mounted optical transceivers for centralized collection. IP cameras are returned through Gigabit single-mode single-fiber/dual-fiber transceivers. The center end is equipped with a POE transceiver to power the front-end dome machine; the outdoor backbone uses anti-rodent armored jumpers and pigtails.

Recommended product portfolio

  • 1/2/4/8/16-channel pure video optical transceiver and rack-mounted models;
  • 1 channel video + 1 channel reverse 485 data video optical transceiver;
  • Gigabit single-mode single fiber (SC optical port) one optical and one electrical fiber optic transceiver, saving half of the fiber in a single link;
  • Gigabit POE powered optical fiber transceiver, powering the dome machine from the ground up;
  • Single-mode dual-core/multi-core armored jumper, anti-rat and anti-trampling.

Solution value

  • Relayless transmission 0–3km/20km/40km/60km/80km optional, image lossless;
  • Optical fibers are not subject to electromagnetic interference and can adapt to strong interference environments such as substations and electrified railways;
  • Reverse 485 channel realizes centralized control of pan/tilt/shield;
  • Analog cameras are zero-replacement and the cost of modification is controllable.
