2.6Close the funnel door and bow start door on the fiber holder. Again ensure that the guide funnel is pushed completely forward to the end of the fiber holder.

Pull the fiber back until the fiber tip is flush with the end of the funnel. To verify the cleave length is still correct, all coatings should align with the hole located in the funnel. Close the back clamp.

Note: for semi-tight buffer fiber, the 250 µm coating may protrude up to 1 mm past the 900 µm buffer. If necessary, re-strip, clean and cleave the fiber to meet length requirements.

2.7Place fiber holder in assembly base and slowly slide fiber holder forward, toward the connector.

Note: Allow 10 seconds for this movement from the time the fiber begins to enter the boot on the connec- tor until the fiber holder bottoms out in the assembly base.

2.8While slowly sliding the fiber holder toward the connector, a bow should start to form in the fiber when the white line on the fiber holder aligns with the white BOW START line on the assembly base. If a bow is not seen, slide the fiber holder back. If a bow is not seen, or if a bow is seen before the two white lines meet, slide the fiber holder back. Re-strip, clean and cleave the fiber, and begin the termination process again.

2.9Continue to slowly slide fiber holder towards connector until it stops. Verify fiber bow again.

Note: The fiber will bow and lift the middle cover for rigid fibers and remain closed for 250 µm and especially ﬂexible 900 µm fibers. This ensures proper fiber insertion force.
