IMPORTANT: Make sure optical fiber is correctly seated in jack.

Right (A)

End of optical fiber (1) must be flush with tip of pin contact (2).

Wrong (B)

End of optical fiber (1) is not flush with tip of pin contact (2).

CUTTING OFF, STRIPPING INSULATION AND CUTTING OPTICAL FIBERS TO LENGTH

Special tools required:

• 61 4 320

To cut off, strip insulation and cut optical fibers to length, use pliers 61 4 321 (1) in conjunction with crimping head 61 4 322 (2) from crimping set 61 4 320.

NOTE: Pliers (1) open automatically as far as they will go when handles are pressed togethe
