Finisar Australia has debuted what it claims is the world’s first twin 16×40 wavelength-selective switch (WSS) for use in next-generation ROADM communication networks.

An extension of the company’s twin liquid-crystal on silicon (LCoS) platform, the Flexgrid® 2x16x40 WSS features significantly more ports than previously available from Finisar or any other WSS supplier. This latest addition to the Finisar WSS portfolio offers expanded flexibility for next-generation ROADM deployments through colourless and directionless add-drop ports in a compact, high-performance WSS.

The company says the Flexgrid® 2x16x40 WSS is the newest in Finisar’s collection of WSS devices, comprising the world’s first LCoS WSS in 2006, the world’s first flexible-grid WSS in 2010, the world’s first 1×20 WSS in 2011, the world’s first 6 THz WSS in 2019, the world’s first quad WSS in 2020, the world’s first C+L WSS in 2020, and the world’s first twin 1×48 WSS in 2021.

Finisar can, on request, provide customized variants of the Flexgrid® 2x16x40 WSS can support a wide variety of port configurations, including 2x30x30, and a wide variety of spectrum configurations, including the advanced C+L-band operating range that Finisar is already featuring in other products. As with all of Finisar’s Flexgrid® WSS products, all variants of the Flexgrid® 2x16x40 WSS support any channel width, from legacy fixed 50/100 GHz to arbitrary customer-controllable channels, using ITU-compliant Flexgrid® technology. Samples of the Flexgrid® 2x16x40 WSS are available now.
