What is the tool used for cutting fiber optic cables at high altitudes called
In fiber optics, the term fiber optic cutter most often refers to a high-precision fiber optic cleaver. Regular scissors, snips, side cutters, flush cutters, and any other tool you might think sufficient for the task will simply not cut aramid yarn cleanly (usually not at all) which results in frustration, and maybe a stopped installation if you happen to be installing bulk fiber optical cable. This. A Fiber Optic Stripper is a specialized tool used to remove the protective coatings and buffer materials from optical fibers without causing damage to the delicate glass core. Choosing the right fiber tools is not just a matter of convenience; it's a matter of meeting industry standards, protecting ROI, and delivering long-term performance. Our cleavers feature a long-life, multi-position blade and an automatic fiber scrap collector to deliver clean, fast, and precise cleaves with an end-face angle less than 0.
