Flexible WSS accommodates advanced network architectures and modulation formats

Thanks to technology advances, wavelength-selective switches now make economic as well as operational sense for a wider variety of applications, including higher-performance edge ROADMs.
Reconfigurable optical add/ drop multiplexers (ROADMs) are now widely deployed in core network (metro and long-haul) applications, where wavelength-selective switches (WSS) have become established as the preferred wavelength switching fabric [...]
