Development of DWDM Mux
DWDM Mux refers to a method of carrying multiple signals on the same transmission medium (line) for communication. Before each signal is sent to the transmission medium, it needs to be modulated according to certain rules, so as to facilitate the transmission of the modulated signal in the medium without confusion, so that the signal has sufficient energy when it is transmitted to the other party, and can be reversed modulation. method to distinguish and restore to the original signal. Commonly used methods of multiplexing include frequency division multiplexing and time division multiplexing, and the application of code division multiplexing is also expanding.
The DWDM Mux transmission system covers the entire telecommunication network, connects all users, and requires a large investment. In order to reduce the cost as much as possible, it is an important way to continuously tap the potential of the transmission system by means of multiplexing, expand the capacity and reduce the cost of the transmission system. In the process of communication development, whether it is a wired or wireless transmission system, while developing new transmission media, the multiplexing technology also develops continuously, and obtains significant economic benefits.
