The 50GHz tunable filter offers a feature to enable the extraction of a wavelength from any one of up to 96 DWDM channels by changing the input light angle to the filter.
“With emerging 40Gb/s and 100Gb/s next-generation optical systems, as well as wider use of Reconfigurable Optical Add/drop Module (ROADMs) in networks, the optical tunable filter will play an important role as a good solution for next-generation optical performance monitor (OPM) to measure the channel power and optical signal-to-noise ratio (OSNR) more accurately,” says Jinghui Li, president at Auxora. “Our 50GHz tunable filter chip provides the flat top, compact size, and a rapid tuning feature which provide a competitive, alternative OPM solution for our customers.”
The 50GHz tunable filter has been shipping to customers since late 2010. It complements Auxora’s WDM product portfolio, based on Nanocode thin film coating technology and proprietary bulk diffraction grating technology, which includes Gain flatness filter (GFF), Corse Wavelength Division Multiplexing (CWDM), and DWDM product family. It is well suited to customers who want to build tunable filter-based OPM and/or wavelength-selectable filter arrays for small-scale ROADMs.
