FBG filter for DWDM

When the channel spacing getting narrower, FBG filter gains its advantages of precise center wavelength position and channel extraction capability. Broptics makes 50G FBG filter specifically for high demanding Dense WDM and Optical Add/Drop Multiplexer applications. While Thin Film filter is technically uneasy to meet 50G filter requirement, FBG filter is matured for mass production. While Array Waveguide Gratings is more economic for high channel count applications, FBG becomes the more cost effective selection. Thanks to TempSmart patent-pending athermal packaging, the temperature variation is within 0.5pm/℃ in the operating temperature range.

Features:
1.Accurate ITU grid
2.Flat top and steep slope  response
3.Very low insertion loss
4.High channel isolation
5.Athermal package

Main applications:
Wavelength selection or  rejection filter
