OpticalDWDM technology refers to WDM technology with a small interval between adjacent wavelengths, and the working wavelength is located in the 1550nm window. It can carry 8~160 wavelengths on one fiber. Mainly long-distance transmission system.A key advantage of DWDM is that its protocol and transmission speed are not related. From the perspective of QoS (quality service), DWDM-based networks respond to customers' bandwidth requirements and protocol changes in a low-cost manner.
