Industry background

The "three remotes" and intelligent inspection of the power system require reliable backhaul of relay protection, telecontrol, and video multi-services; substation ground potential differences and switching operation overvoltages pose threats to copper cables, and the intrinsic insulation of optical cables is an inevitable choice for power communications.

Customer pain points

  • 220kV/110kV site has strong interference, serial communication bit errors, and burned ports;
  • Termination and protection of the last mile from optical fiber to switch cabinet/box transformer;
  • Requirements for co-fiber dispatching of voice traffic and data services;
  • The wiring in the old computer room is messy and maintenance is difficult.

Recommended product portfolio

  • 1/2/4-way bidirectional RS485 data optical terminal, optical isolation protection communication port;
  • 8 telephone lines + 1 network optical transceiver, carrying dispatching traffic;
  • Three-in-one data optical transceiver, multi-service single fiber multiplexing;
  • SFP Gigabit single-mode 10–80km optical module to build station and station ring networks;
  • 24-port 24-core FC single-mode fully equipped ODF patch panel with standardized ends.

Solution value

  • Complete electrical isolation to prevent equipment damage due to ground potential difference;
  • The bit error rate is reduced to the order of 10⁻⁹, and the telecontrol channel is stable;
  • ODF is unified into terminals, and the troubleshooting time is significantly shortened;
  • Outdoor armored optical cables are suitable for box-type transformers and tower environments.
