I. Core Principles of Wavelength Switching Relying on tunable optical devices and intelligent network management for dual control, seamless wavelength switching can be achieved without replacing hardware or interrupting services, ensuring transmission rate and link stability throughout the entire process. The core formula to remember first is c = f × λ. Since the speed of light c is constant, as t...
