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.
