Wavelength selective switching components are used in WDM optical communications networks to route (switch) signals between optical fibres on a per-wavelength basis.

Wavelength Selective Switches (WSS) are a critical enabler of Reconfigurable Optical Add-Drop Multiplexers (ROADMs)— the heart of these systems. Manufacturing test engineers across the …

Initially, ROADMs utilized fixed-grid Wavelength Selective Switch (WSS) technology that functioned on a specific channel plan and spacing. These ROADMs were often based on …

Wavelength Division Multiplexing (WDM) is a fiber-optic transmission technique that enables the use of multiple light wavelengths (or colors) to send data over the same medium.

Use our modules for wavelength routing to combine, manipulate, or separate multiple WDM and DWDM signals from 100 GHz spacing down to < 25 GHz, all with no crosstalk. Based on our …

WSS technology enables network operators to remotely adjust, add, or drop specific wavelengths of light without disrupting other traffic within the network. The Wavelength Selective Switch …

Nokia’s WDM optical line systems support a wide range of C-band and L-band options. C-band only systems are used for applications where ultimate scalability is not needed, while L-band …

Sep 8, 2020 · The wavelength selective switch (WSS) is the key component in all commercial ROADM systems. Liquid crystal on silicon (LCoS) technology dominates current WSS …

Wavelength selective switches (WSSs) are components used in wavelength division multiplexing (WDM) optical networks to route signals between optical fibers according to wavelength. The …

The WSS provides WDM functions including demultiplexing, multiplexing, space division switching, wavelength blocking, and channel equalization. Multiple 1xN WSS’s can be further …
