6.0 Connector Reusability
6.1
Should it become necessary to separate the connector
and fiber, e.g. to reset the fiber protrusion, the
activation cap within the connector can be deactivated.
This is accomplished by first removing the connector
from the port on the protrusion setting tool. Place
the connector atop the deactivation station on the
tool base, with the activation cap face up, and press
firmly downward. This action releases the gripping
mechanism within the connector. Limit the number of
times a given connector is reused to one. A connector
with its cap pushed down without a fiber inside, or
with a fiber only partially inserted, is not reusable.
6.2
To correct large, deep imperfections on the fiber face,
restart at step 2.0. Replace the lapping film disc for
each re-use of the connector.
6.3
To correct small, shallow imperfections, such as
small chips, reinsert the connector in the protrusion
setter. Hold the fiber with your fingers and create
a bow in the fiber. The bow length should be
approximately as shown in Step 4.3 for 900 µm,
and approximately as shown in Step 4.4 for 250
µm. Hold the fiber bow and begin completing
Steps 4.5 through 5.8. Use a new piece of lapping
film per Step 5.1.

7.0 Troubleshooting
7.1
If the fiber is not visible with the flashlight in step
4.2, and bow increase is not seen in step 4.6, check
the bow height by tilting the middle door on the
fiber holder to the vertical position, as shown in the
photo to the right. If the fiber bow is taller than the
rib in the center of the middle door, marked with
a dotted line illustrated on the right, then the fiber
bow is too high. The fiber has hit a snag inside
the connector. Remove the fiber and fiber holder
from the protrusion setter. Open the latch on the
fiber holder's buffer clamp. Re-adjust the fiber
so that fiber curl is downward as shown in step
3.12. Attempt inserting the fiber into the connector
again per section 4.0. If a high bow occurs again,
re-strip the fiber and re-cleave per section 3.0. If
the same high bow problem occurs again, mark the
connector as defective and get a new connector.
7.2
If the a connector falls off 250 µm fiber, install a
new connector, and ensure that the 250 µm acrylate
has been stripped off 40 mm long, per step 3.2.
Also ensure cleave length is 19 mm per step 3.7.
Also ensure that the termination matches photos
4.2, 4.4, and 4.6.
7.3
For APC only, if insertion loss is 2.9 dB - 3.6
dB, then inspect the lapping film per section 5.7.
Polish the connector if it has not been polished yet.
