3Carefully dress the excess fiber into the ramp of the fiber spool tray. Wrap the fiber around the spooling cylinder one to two times depending on the length of the fiber. The diameter of the spool tray is matched to the bend radius of the fiber. Also ensure that the fiber is routed under the retaining flanges and through the pegs of the fiber tray for proper routing to the optics modules. Figures 4-5 and 4-6 illustrate the housing lid and fiber spool tray:
