SANTEC unveils LCOS-based WaveProcessor Arrays for ROADMs

SEPTEMBER 9, 2010 -- SANTEC Corp. has introduced its WaveProcessor Array (WPA) family of products based on Liquid Crystal on Silicon (LCOS) for next-generation reconfigurable optical add/drop multiplexers (ROADMs).

SEPTEMBER 9, 2010 -- SANTEC Corp. has introduced its WaveProcessor Array (WPA) family of products based on Liquid Crystal on Silicon (LCOS) for next-generation reconfigurable optical add/drop multiplexers (ROADMs). The WPA modules are designed to enable system providers to efficiently manage bandwidth with the flexibility required by intelligent optical transport networks (OTNs).

The WPA family includes the WPA-44 4x4 wavelength-crossconnect switch; the WPA-8 and WPA-12 wavelength blocker arrays with port counts of 8 and 12, respectively; and the TFA-8 tunable filter array with a port count of eight that enables colorless receivers.

The WPA-44 is the first integrated commercial product of its kind, SANTEC asserts; it supports colorless, directionless, and wavelength contentionless operation.

SANTEC says the WPA family is the new generation of intelligent products based on the company’s proprietary LCOS technology with proven long-term reliability. The WPA-8 offers a channel selection mode, in which the user can select a single channel within the ITU-T 50-GHz grid of 96 channels. The WPA-8 and WPA-12 have an ITU-Grid mode, in which the user can control the channel bandwidth and the attenuation levels within the ITU-T 50-GHz grid. The WPA-44 has the ITU-Grid mode and a full control mode (FC mode). The FC mode enables a high-resolution waveshape setting in either C-band or L-band via pixel-by-pixel setting in the LCOS.

“SANTEC’s WPA family has many advantages for next-generation OTN,” said Dr. Noboru Uehara, department manager of R&D of SANTEC. “We are extremely pleased with the advantages of LCOS technology in our WPA platform which provides software-oriented flexible and intelligent solutions for our customers.”
