Coating residue may be removed using a lint-free pad soaked with high purity alcohol. Lower purity alcohols may leave excessive residue on the fiber. Fiber preparation for splicing and termination requires removal of a section of the protective cable elements, such as the jacket, armor (if present), and buffer tubes. This gel must be carefully cleaned as. Fiber strippers are precision tools that reliably and cleanly remove a defined length of coating (often 30–40 mm) from a fiber end so that the bare glass is exposed without scratching or nicking it. The causes are usually lack of training, lack of practice and lack of understanding of what is a “good” and/or “acceptable” fiber optic connector. Required consumables are sold separately. The paper also discusses troubleshooting methods when re-polishing is required due to the various post polishing failures. The document is intended to inform and educate about polishing processes and commercial automated polishing equipment with various fixturing in order. At the heart of any robust fiber optic network lies a crucial process: Preparing a fiber cable for termination of a connector or splice. Whether you're installing a new network, expanding an existing one, or.
