Outstanding Performance
LCOS based Programmable Optical Filter
WSS-2000NEW!
Programmable Arbitrary Spectral Shaping
The WSS-2000 is an LCOS-based Programmable Optical Filter. Santec's proprietary LCOS (Liquid Crystal on Silicon) technology inside the WSS-2000 offers the ultimate flexibility, enabling the user to program a limitless range of optical filtering, attenuation, and switching schemes. In addition, the phase control function is also available. The WSS-2000 is an enabling technology for investigating next-generation optical networks by utilizing the filter as an optical equalizer of high-speed signals, as an adaptive channel filter for advanced optical transmission systems (DWDM, OFDM), as a WSS emulator or as a flexible test and measurement system.
Demo units are available.
