This Fibre Optic Splicing - Termination Safe Work Method Statement (SWMS) provides clear guidelines for safely performing tasks related to the repair, splicing, and construction of new joints in fibre optic cabling, especially near roads, railways, or shipping lanes. Operators that are familiar with electronic components and wiring may not be aware of the special needs of optical fibers and fiber optical rotary joints (FORJs). Although flexible, fiber optics are made of glass and this property makes it very fragile. It provides an expert-curated supplier directory, buyer-focused technical background information, and structured selection criteria to support professional procurement decisions.
