8-Channel Video Optical Transceiver

Overview:

The 8-channel video digital multiplexing optical terminal is a compact multi-service fiber transmission product tailored by our company for the security surveillance market. It can transmit up to 8 channels of one-way video, 4 channels of data, 4 channels of two-way audio, and 2 channels of Ethernet over a single optical fiber, meeting various user requirements. It adopts internationally advanced all-digital video uncompressed technology, as well as advanced technologies such as Time Division Multiplexing and Wavelength Division Multiplexing to transmit eight channels of video and multiple channels of two-way audio and data over the optical fiber in real time, synchronously, without distortion, and with high quality. Its high-quality video effects and two-way data transmission meet various user needs. The plug-and-play design makes installation simple and easy, requiring no on-site adjustment. Both the optical module and core circuits use standard components with high stability. All optical and electrical interfaces comply with international standards and are suitable for different working environments.
