34 ASC25 Instruction Manual
Caution
To remove the core cover (0.5 mm in diameter, semi-transparent), if
the knife edge of jacket remover is damaged or if mal-manipulation of
the knife is occurred, the clad (0.23 mm in diameter, transparent) of the
optical fiber may be damaged (becoming cloudy in the surface).
The clad of H-PCF optical fiber is an important section that protects the
Silica glass core and that assures high strength and high reliability of
the optical fiber. Accordingly, damaged surface of the optical fiber may
result in break of fiber at that portion in the succeeding process or
during the manipulation of connector. Therefore, the clad shall be
confirmed to have no damage on the surface by giving inspection
described below before entering succeeding step, independent of
presence/absence of cloudiness.
(5) Cut off the tension member by 5 to 6 mm using scissors, and bring a spring on through the
optical fiber cord.
(6) Insert the optical fiber through a ferrule.

Figure 9.14 Insertion of ferrule
Note: Assure that the optical fiber is inserted into the ferrule until either the tension
member is folded to protrude to outside the ferrule by 1 to 2 mm, or the tension
member enters the ferrule by about 1 mm.
(7) Using a crimping tool, fix the ferrule and the optical fiber. The work shall be done with
special care for the position of ferrule and the groove of the tool.
(8) Using an optical fiber cutter, cut off the protruded portion of the optical fiber at the tip of
ferrule. On cutting the optical fiber, debris of the optical fiber may be attached to the
cutting edge of the fiber cutter due to static electricity. Check the debris on the cutting
edge before and after the cutting work. If the debris of optical fiber remained on the cutter
knife edge, remove the debris with tweezers or other means.
