DWDM technology uses the bandwidth and low loss characteristics of single-mode fiber and uses multiple wavelengths as carriers to allow each carrier channel to transmit simultaneously in the fiber. Compared with the universal single-channel system, dense WDM-DWDM not only greatly improves the communication capacity of the network system, fully utilizes the bandwidth of the optical fiber, but also has many advantages such as simple expansion and reliable performance, especially it can directly access A variety of services make its application prospects very bright.
