SIGNAL TRANSMITTING CABLE |
摘要 |
A fibre optic cable 1 includes a core of primary coated optical fibres 2 embedded in an inner layer 3 of acrylate material, having sufficient tensile strength when cured to lock at least the outermost fibres 2 in place and still allow the fibres to be easily broken out of the assembly for termination and splicing purposes. The hardness of the acrylate layer 3 is such that at least the outermost fibres 2 of the bundle are restricted from moving axially relative to the inner layer 3. The inner layer 3 is then surrounded by a loose thin jacket 4 formed from a mixture of high density polyethylene having a Shore hardness greater than or equal to 60 and a generally uniformly distributed slip agent, including a polyether modified poly (dimethylsiloxane) material such as polyether modified hydroxy functional poly (dimethylsiloxane) material. The mixture from which the outer layer 4 is formed is compacted by means of heat and pressure. The outer layer 4 may also contain a mineral filler, such as calcium carbonate and/or titanium dioxide, in order to improve the stability of the dimensions of the outer layer 4 as the temperature changes.
