Description:
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/¢J in the operating temperature range. |
