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.

Wavelength Selective Switch (WSS)

Increasing demand for network services is driving the introduction of new transmission formats and channel management technologies that facilitate the efficient use of optical bandwidth for extremely high data rates.

While the introduction of coherent techniques such as Dual-Polarization Quadrature Phase Shift Keying (DP-QPSK) enables 100 Gb/s transmission within a 50 GHz channel, traffic with higher data rates, including 400 Gb/s and 1 Tbit/s signals of the future, are not expected to fit inside 50 GHz wide channels. These higher data rates require that channel spacings are flexible and can be increased to allow the use of new transmission formats.
