DWDM filter (FBG only)

Overview

DWDM filter (FBG only)

Xiaoxiao Photon's DWDM FBG fiber Bragg grating filter has attracted more attention due to its flat top and steep spectral slope. Using our unique toe mask technology and FBG writing technology, we have fabricated DWDM fiber grating filters with an isolation greater than 40 dB and a reflection bandwidth of -25 dB. The reflection bandwidths are less than 1 nm (100 GHz), 0.5 nm (50 GHz), 0.25 nm (25 GHz), 0.13 nm (12.5 GHz), and 0.06 nm (6.25 GHz), respectively.
