What is Digital Video Multiplexer Used For?
In the modern society, video multiplexer plays an important part in most public places and special events to monitor and record the real-time videos. Video, after years of development, has become one important way of communication after audio. Video multiplexer, as the typical application of videos, has also played an important party in improving the office efficiency technology, and in many ways have mature application.

At first, let see what’s exactly a video multiplexer, to be simple, a video multiplexer is an transmission device that convert 1 to more channels analog video signals to optical signals using various encodes and finally enable them transmit via the optical fiber medium. Since two technologies are usually used for this conversion, it can be divided into analog video multiplexer and digital video multiplexer. The principle is to modulate the signals to the light and transmit through fiber optics.
The video multiplexer encodes the multi-channel video signals and convert them to optical signals to transmit on optical fibers, fiber-optic video multiplexer can simultaneously transmit 1-64 channels of 8bit digitally encoded video/return or bidirectional data/ un-directional or bidirectional audio/ Ethernet/ Telephone/ Dry contract over one multi-mode or single mode optical fiber. These multiplexers are typically used in applications where the cameras have PTZ capabilities.
