FBG-based OADM

FBG itself provides unique functions:
 Very low insertion loss
Low IL
 Flat-top response
 Steep slope
 Very high channel isolation
Best choice for 50G OADM
 TFF can’t match the specs
High ch.
isolation
 AWG can’t match the cost

FBG benefits over TFF
 Time saving for spec-in
 Cost saving for model
introduction & ramp up
 Economic ordering qty to
reduce inventory

Laser Stabilizer & Wavelength Locker

FBG acts as an external mirror or cavity for laser diode
 Fixed laser emission behavior
 Enhance accuracy
 Allow production tolerance
