ber.

Preferred
Procedure

opening. Rotate the pipe-cleaner slowly as you do this.
2. Clean the adapter by rubbing a new, dry cotton-swab over the surface using
a small circular movement.
3. Blow away any remaining lint with compressed air.
Cleaning Bare Fiber Ends

parallel beam. The end of a ber can often be scratched. You make a new cleave. To do this:
1. Strip o the cladding.
2. Take a new soft-tissue and moisten it with isopropyl alcohol.
3. Carefully clean the bare ber with this tissue.
4. Make your cleave and immediately insert the ber into your bare ber adapter in order to
protect the surface from dirt.
