What Is a Video Relay?

The video relay DVOP-R is designed with a dedicated ASIC and adopts the most advanced digital video and optical fiber transmission technology in the world to realize large-capacity real-time synchronization of video, data, Ethernet, voice, switching and other signals without distortion, High-quality ultra-long distance transmission.

Video repeater

Right!

Video Relay DVOP-R is dedicated

On a single fiber, a single-stage relay can achieve long-distance transmission of more than 200 kilometers with a hundred megabytes, and synchronous transmission of a single-stage fiber with a length of more than 120 kilometers. Relying on the company's professional regeneration, clock re-extraction, and re-amplification "3R" technology, it completely eliminates the series of problems caused by the "back-to-back" relay method, such as the degradation of image transmission quality, noise superposition, and clock jitter, thereby achieving infinite levels Number of relays are losslessly cascaded. Large-capacity digital video transmission relay equipment can provide broadcast-level image quality, high-fidelity audio effects, and high-speed data transmission. It automatically adapts to full-format video signals. The high-speed synchronized all-digital optical transmission channel ensures high-quality video and data. Transmission of voice signals.
