Bare Fiber Safety The broken ends of fibers and scraps of fiber created during termination and splicing can be extremely dangerous. The ends are extremely sharp and can easily penetrate your skin. While these cables are engineered for durability (with some rated to last 25+ years), they are not invulnerable. This can involve working with lasers, precision equipment, micro-scale glass fragments, heights, tools, and working near or with utility or electrical infrastructure. Know the standards that apply to your work Whether you're installing new fiber optic cables or troubleshooting and repairing an existing fiber network, a working knowledge of the regulations that apply to your. As electrical professionals, most of us take fiber optic (FO) safety for granted. Since fiber optic cable carries no electricity, we don't worry about electrocution. Similarly, we don't think about personal or property damage due to fire because it isn't a source of heat Understanding the safety. Fiber optics has become a standard for high-speed data transmission, carrying information as pulses of light through incredibly thin strands of glass or plastic. While this technology enables fast and reliable communication, the introduction of any new infrastructure often brings public questions. Fiber optic cables are the backbone of modern communication systems. They deliver enormous volumes of data through strands of glass thinner than a human hair.
