12 Dec 2012 With the deployment of DWDM systems, high isolation channel is necessary to avoid the cross talk. We offers reflection filters based on fiber Bragg gratings featuring flat top response and steep roll down spectral that are available individually packaged or be combined with multiple filters to form a complete add/drop module.
