With the deployment of DWDM systems, high isolation channel is necessary to avoid crosstalk. Our reflection filters, based on fiber Bragg gratings, feature flat top response and a steep roll down spectral range that is available in an individual package or combined with multiple filters to form a complete add/drop module.

--Low insertion loss and crosstalk
--Low dispersion
--Excellent long-term stability
--Superior proof strengths
Applications
--DWDM system 50/100/200 GHz in fiber narrowband signal filtering
--OADM module, mux/demux
