15.3Cut connectors/fusion splice sleeves from the ends of the fiber stored inside the Wall Outlet and Point- of-Entry (POE) Cover of the damaged 900 µm fiber. Pull existing (gray) 900 µm fiber from installed duct and discard per company practice.

Note: If pulling 900 µm is difficult the window cuts made in step 2 may be used as intermediate pull back locations.

15.4Wrap 2'-4' (600-1200 mm) of the new white

900 µm fiber into the Wall Outlet to create enough slack for connector termination and begin pushing it into the duct.

Note: Keep new 900 µm off of the floor and clean as it is pushed into the duct to reduce floor debris from being carried into the duct.

15.5When the new white 900 µm fiber comes through each window cut, pull gently at that point to remove slack.
