SECTION A
Warnings, Recommendations and Overview
1. Most fibers can be mechanically stripped without the aid of chemicals or heat. If the fiber is not mechanically
strippable, contact 3M's Training Department or the cable manufacturer for their recommendations.
2. The recommended cleaning solvent for connectors and tools is isopropyl alcohol (reagent grade, 99% or
better). It may be purchased from laboratory supply companies. Isopropyl alcohol may also be used to clean
the lapping acetate and stripping tool when necessary. Do not use acetone for cleaning.
3. For safety reasons, no chemicals have been shipped with the 3M brand Field Termination Kit. We have,
however, included bottles for the alcohol and water.
Note: Carefully follow safety,health and disposal information on container label or Material Safety Data
Sheet for isopropyl alcohol being used.
4. Please contact the 3M Telecom Systems Training Department if you have any questions concerning
chemicals or procedures.
Warning: Do not view fiber ends if they are laser illuminated. Eye damage may result. Illuminate fiber
ends with white light only.
5. The connectors described in this manual have pre-radiused PC "domed" ferrule ends to ensure low
attenuation and the best reflection performance. All polishing should be done on the soft polishing pad
only, as described in this manual.
6. The 3M brand connectors with PC finishes are completely intermateable with flat finished connectors. PC to
flat terminations actually provide improved performance over flat to flat terminations. PC to PC terminations
as produced while using this manual, however, offer the best performance.
7. Safety glasses should be worn when working with optical fibers.
8. Appropriate containers of clean, dry, compressed air may be obtained from photographic supply stores. Do
not use types that leave a residue.
