      • information
      • multi-channel digital video optical transceiver can transmit multi-channel high quality video,

        multi-channel audio or multi-channel bi-directional audio, multi-channel positive/reverse/bi-directional asynchronous data in one fiber.

        it adopts full digital uncompressed techniques, and supports high-resolution movement and still picture-undistorted transmission.

        it is now widely used in security monitoring and control system, highway, traffic control photographic system, automation and intelligent residence.
