Heat shrinkable products are available in a broad range of types, of which heat shrink tubing is the most well-known. A lesser known type are ‘heat shrinkable fibre optic splice protectors’. When do you use fibre optic splice protectors, and how do they work? Read it in this blog!
Properties of heat shrinkable fibre optic splice protectors
Heat shrinkable fibre optic splice protectors have a shrink ratio of 2:1 and are transparent. They are made of crosslinked polyolefin and can therefore be used in temperatures ranging from -45 °C up to +100 °C. They are halogen free.
Heat shrinkable fibre optic splice protectors consist of three parts: a steel rod, to support the connection and protect it against breaking, an inner tube, which shrinks when heated, and which connects the glass fibre, and an outer tube, to keep the previous two parts together.
For which purposes are heat shrinkable fibre optic splice protectors used?
Fibre optic splice protectors are used to repair broken glass fibre wires and to create new connections, from glass fibre to glass fibre. The connection is made by the inner tube, which shrinks when heated.
