Flexband 1xN WSS

Gen-2 LightFlow™ Flexband WSS

II-VI's Flexible Bandwidth Wavelength Selective Switch (WSS) series is an important innovation of WSS technology, which enables the next generation networking towards higher capacity, with flexible bandwidth in 12.5GHz granularity - 4 times density compared to the standard fixed 50GHz channel spacing.

Powered by the Gen-2 LightFlow™ switch engine, II-VI’s Flexband 1xN WSS series also inherits the key characteristics from II-VI’s widely deployed standard WSS products, such as the high reliability and low power consumption, while featuring improved performance. Its backward compatibility allows the NEMs to minimize the investments in the future proof network equipment development.
