The Classification of the Digital Video Multiplexer
With the development of technology and the increasing demand on security, the Monitoring multiplexers are widely applied for most security applications such as remote business meeting, distance education, hospital, and many other security engineering applications.
Current multiplexer technology is becoming more and more mature, the monitoring multiplexer can achieve in a core optical fiber transmission on multiple video, audio, data, telephone, Ethernet, E1 signal, alarm and so on many kinds of signals
From the supported channels: there are 1, 2, 4, 8 channel video multiplexers and more channel video multiplexer with PTZ control data
From the single types: there can be divided into digital video multiplexer and analog video multiplexer.
From the interface types: there are 1-64 channels Video multiplexer, Video + Data Multiplexer, Video + Audio Multiplexer and Video + Audio + Data multiplexer, Phone Multiplexer, Ethernet Multiplexer, etc.
Other multiplexer:
SDH Multiplexer (Synchronous Digital Hierarchy, Synchronous Digital series) capacity is biger, general 16 e1 to 4032 e1.
SPDH Multiplexer (Synchronous Plesiochronous Digital Hierarchy) is between PDH and SDH. It is a PDH transmission system that based on the PDH code speed adjustment principle at the same time, use as far as possible parts of the SDH network technology.
PDH Multiplexer (Plesiochronous Digital Hierarchy, quasi synchronous Digital series) is small capacity multiplexer and generally used in pairs, also called point to point application, capacity is commonly 4E1, 8E1, 16E1. For more info, please browse our website.
