Application of a heat shrink splice protector immediately after fusion splicing will protect the spliced optical fibre during installation, handling and storage for many years of the fibre’s lifetime. The heat shrink sleeves have been tested to Telcordia (Bellcore) Spec GR1380. Each protector has a clear outer polyolefin tube, an inner copolymer dielectric sleeve and a stainless steel strength member for low heat absorption and electrical resistance. Typically, these heat shrink splice protectors are used in: splice trays, splice/patch subracks and COFTU’s.
