Optical SplitterPossible major modifications

• Scenarios
• PLC chip
• Input Fiber array
• Output Fiber array
• The housing structure and interface adhesives
  remain the same
• The qualification tests are performed at the
  component, not module, level
• The combination of a fiber array (input or
  output) and PLC chip will be treated as a new
  device, and will be qualified as option A in the
  splitter/module design changes

5
All required optical measurements include

• Optical band-pass from 1260 to 1625 nm
• Insertion loss
• Uniformity (derived from the insertion loss
  measurement)
• Return loss of the input port
• Directivity
• Polarization Dependent Loss
• all at 1310nm, 1490 nm, 1550nm, 1625nm
• Polarization Mode Dispersion at 1550nm (due to
  lack of calibration standards at the other
  wavelengths)

Qualification due to Fiber Array change
(scenarios 2 and 3) input and/or output fiber
array

• 7 1x32 and 7 1x16 splitters for each group
  (component level)
• 11 units for each group if a single product is
  qualified
• Initial characterization
• Insertion loss
• Qualification per GR 1221 groups B and E
  (partial)
• Final characterization
• Insertion loss
