First Demonstration of Hitless Spectrum Defragmentation using Real-time Coherent Receivers in Flexible Grid Optical Networks

Not Accessible

Your library or personal account may give you access


We experimentally demonstrate for the first time hitless spectrum defragmentation using the wavelength sweep capability of real-time digital coherent receivers over entire C-band. The network simulations of blocking performance and its dependence on wavelength sweep speed confirm the feasibility of spectrum defragmentation.
