Description

technical field

[0001] The invention belongs to the technical field of optical communication, and in particular relates to an optical channel establishment method, a wavelength division device and a wavelength division system. Background technique

[0002] WDM (Wavelength Division Multiplexing) technology is a technology that simultaneously transmits multiple wavelength optical signals in one optical fiber. Its adoption solves the problem of network bandwidth caused by the rapid growth of image and data services in recent years. The problem of great demand. The traditional WDM network is a point-to-point static network. With the explosive growth of IP services and the uncertainty and unpredictability of IP traffic itself, the requirement for dynamic allocation of network bandwidth is becoming more and more urgent. A rapidly changing business environment requires a new type of optical network with strong dynamic performance. The emergence of ROADM / WSS (Reconfigurable Optica...
