Fiber Optical Transmitter & Receiver

Overview

DDT-S-T/R020SF

The digital optical transceiver can realize transmitting two channels positive video in single-core optical fibers. It uses digital symmetric multiplexing / wavelength division multiplexing and kilomega fiber transmission technology,transmitting video signals in single-core fiber with real-time synchronization, fidelity and high quality.

The network management function is optional for this series of optical transceiver. The running status of optical transceivers can be monitored by only inserting one network-managing card.

In addition, we accept products OEM/ODM services.
