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 Bellcore (Telcordia) 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. A shrink sleeve is completed in 90 seconds, at a temperature of 90˚C, to Ø2.4/Ø2.5mm dia. Typically, these heat shrink splice protectors are used in: Corning Openable Joints ( e.g. Telstra No: 49400287 & 49400297, etc) and other common Subrack items.
