                                Since the 1980s, the fiber optic telecommunications industry has moved away from older cable construction methods to eliminate toxic materials, including lead. Understanding what fiber does not have lead is crucial, as modern fiber optic cables are predominantly made from highly purified silica glass or plastic, with no lead used in the core or cladding.
