The term PDH stands for Plesiochronous Digital Hierarchy. This multiplexer is type of point to point optical transmission equipment that can be mainly used for sending the broad quantities of data via the digital media transport such as microwave radio systems and fiber optic systems. Actually, the PDH multiplexer is specially designed for highly integrated structure that offers 16 standard E1 interface along with a single channel of order wire. Nowadays, this multiplexing device is more popular among the telecommunication operators, government and all types of entities, because it is well suitable for all businesses.
The PDH multiplexer system is fully based on the theory. If you have couple of identical clocks with same style, brand and everything, you will not expect that to run at high speed. The transmission of this multiplexer system can combines the received data streams, reconstruct the original data and then send back out at accurate rates. The specialty of this multiplexing system is allowing the user to manage the network and also capable to de-multiplex the higher level of carrier. The major factor to be considered while using this system is cost of equipment used within the network.
Basically, there are several different types of PDH multiplexer available that performs different operations at various instances. The PDH multiplexer can use fiber transmission technologies and have reliable interface to connect with light loop device, exchanger and also the multiplexer directly to create the special or micromini network. These types of multiplexers are highly stable and also easy to install and maintain. It looks very smaller in size and greatly supports on single digital service telephone. This fiber optic multiplexer is also suitable for point to point application and low capacity of remote transmission as well. Thus, the fiber optic MUX is widely used in data application and voice field.
