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
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
Qualification due to Fiber array changeGR 1221 Environmental testing
Qualification due to PLC chip changeGR 1209 test requirements
Qualification due to splitter/module design changes • Option A • Splitter not qualified • Module remains the same • Options B • Splitter qualified by any supplier • Module not qualified • Option C • Splitter not qualified • Module not qualified • Complete test program
Option A – GR 1209 test requirementsModule previously qualified, new splitter component
Option A – GR1221Module previously qualified, new splitter component
Option B – GR 1209New Module, splitter previously qualified If the initial and final optical measurements don’t conform to the specifications, all required optical measurements should be performed
