Auxora introduces 50GHz tunable filter chip

Auxora Inc., a provider of optical thin film filter (TFF)-related products, announced its 50GHz channel spaced Dense Wavelength Division Multiplexing (DWDM) tunable filter chips.

Auxora Inc., a provider of optical thin film filter (TFF)-related products, announced its 50GHz channel spaced Dense Wavelength Division Multiplexing (DWDM) tunable filter chips.

The 50GHz tunable filter provides 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 Modules (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, 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 complements Auxora’s WDM product portfolio, based on Nanocode thin film coating technology and proprietary bulk diffraction grating technology, including GFF (Gain flatness filter), CWDM (Corse Wavelength Division Multiplexing), and DWDM product families. The new offering is well suited for customers who want to build tunable filter-based OPM and/or wavelength-selectable filter arrays for small-scale ROADMs.
