It's a new line of Wavelength Selective Switch (WSS) called TrueFlex. The devices have just started sampling and should be ready for production shipments later this year, executives said. JDSU already sells WSSs based on micro-electro-mechanical systems (MEMS) Mirrors, but TrueFlex is built from liquid crystal on silicon (LCoS). The wavelength assignments on an LCoS WSS can be reassigned in software, making it a good option for flexible-grid ROADMs. Finisar Corp. (Nasdaq: FNSR) already has LCoS-based WSSs and had been touting flexible-grid capabilities since at least 2010.

JDSU says TrueFlex WSSs will be available in sizes of 1x9 and smaller for metro networks and in larger sizes for core networks.
