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.

Spring 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.
