Description 
 
Product Introduction
WT series 4-channel video +1-channel bi-directional data digital multiplexing optical transceiver adopt the advanced international digital video and optical fiber transmission technology, and implement the transmission of real-time & synchronization, no-distortion and high quality to 4-channel video + 2-channel bi-directional data signal on the single-core optical fiber. 4-channel video + 2-channel bi-directional data optical transceiver adopt the full digital video non-compression transmission technology and high quality video effect, which can meet the user’s requirement; the play-and-plug design makes the installation more convenient and easier, and it is unnecessary to implement the spot adjustment; its optical module and core circuit adopt the imported components that have high stability, and all optical & electrical interfaces conform to the international standards, which is applied to the different working environment. This optical transceiver with video status indication can monitor the normal operation of system.
This optical transceiver adopts the structure modularization design, and the user can flexibly select or customize the configuration according to the spot detailed conditions; the above optical transceiver can adopt the installation mode of independent type or framework type.
