FBG-based OADM

• FBG itself provides unique functions
• Very low insertion loss
• Flat-top response
• Steep slope
• Very high channel isolation
• Best choice for 50G OADM
• TFF cant match the specs
• AWG cant match the cost

Flat-top
Low IL

FBG, the best choice for 2/4/8 ch 50G OADM
13
FBG-based Gain Flattening Filter

• FBG provides unique features for GFF
• Short prototyping lead time
• Accurate gain profile fitting
• Flexible order qty

FBG benefits over TFF Time saving for spec-in Cost saving for model introduction ramp up Economic ordering qty to reduce inventory
14
Laser Stabilizer Wavelength Locker

• FBG acts as an external mirror or cavity for
  laser diode
• Fixed laser emission behavior
• Enhance accuracy
• Allow production tolerance

Stabilizer Makes EDFA design easier and accurate Wavelength Locker Allows narrower bandwidth and higher channel counts
15
NTE Ceramic Athermal Package

• Zirconium Tungstate (ZrW2O8), the incredible
  shrinking materials
• Negative thermal expansion crystallized structure
• Compensates for FBG thermal effects
• CTE tuning range good for photosensitive
  specialty fiber thermal compensation
• Compact
• Minimize FBG packaging
• Possible multi-FBG package
