The original intention of DWDM system design is to meet the demand for long-distance capacity. However, with the development of the Internet, the demand for bandwidth has increased dramatically. DWDM is developing towards metropolitan areas or receiving terminals. The regional network architecture is more complex and how to facilitate supply, reduce the first installation cost and the ability to extend the length, or the demand for the number of channels, has become a key factor in this development. The current market is mainly concentrated on the number of channels 80-96, with channel spacing ranging from 200GHz to 50GHz.
