2-Channel Video Optical Transceiver

Overview:

The 2-channel video series optical terminal is a compact multi-service fiber optic transmission product tailored by our company for the security surveillance market. It can transmit up to 2 channels of one-way video, 2 channels of data, 1 channel of two-way audio, and 2 channels of Ethernet over a single optical fiber, meeting user requirements. Utilizing internationally advanced all-digital uncompressed video technology, it transmits two video channels and multiple data channels over optical fiber in real-time, synchronously, without distortion, and with high quality. The high-quality video performance meets 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, ensuring high stability. All optical and electrical interfaces comply with international standards, making it suitable for various working environments.
