1x2 / 1x4 Flexgrid^®
Wavelength Selective Switch (WSS)
The 1x2 / 1x4 Flexgrid® Wavelength Selective Switch (WSS) by Finisar enables programmable
optical channel switching and attenuation through the proprietary use of Liquid Crystal on
Silicon (LCoS) technology. The WSS provides advanced functionality through embedded
software in a compact module designed for low cost reconfigurable network edge
applications.
Each optical channel within the WSS can be independently and hitlessly switched to any
port with full attenuation control. Finisar's Flexgrid technology provides dynamic control of
the channel widths within the WSS, the key element in a Reconfigurable Optical Add/Drop
Multiplexer (ROADM). Once deployed, channel plans are configurable 'on-the-fly', meaning that
channel bandwidths can be adjusted to most efficiently carry future demands as they arise.
In network edge applications, low cost and small form factor are key requirements. The WSS
addresses these needs through a number of design innovations, including:
 Balanced, athermal optical design, eliminating the need for thermal stabilization
 Advanced HTCC hermetic package technology, enabling a compact high reliability module
 Simple, highly manufacturable optical design
 High density motherboard, minimizing module size
The product features excellent optical performance, supporting 10 Gb/s through 400+ Gb/s
traffic on Flexgrid®, 50, 100 or 200GHz ITU optical channels. The WSS uses the same core
Liquid Crystal on Silicon (LCoS) optical switching element used in Finisar’s 1x9 / 1x20 family
of WSS.
This fully integrated intelligent module offers flexible, upgradable WSS functionality and
excellent optical performance in a compact module that addresses high density card design
requirements.
