QC3: Verify routing with a light source

Check all fiber sub-bundles on both sides of the module:

Position the light source at the first tile of a cell - check that a fiber in the correct bundle is lit .

Move the light source one tile at a time - check that a fiber is lit at each step.

Note the source position when no fiber is lit - it should correspond to the beginning of the next cell.

Repair any problems.

Sign and date the check sheet.
