This specialist version of Cat5E SF/UTP (foil and braid screen) has a very tough polyurethane outer jacket, and has moderate flexibility. The jacket is two-layer, the inner layer is low fire hazard material, so the cable can be classed as 'low fire hazard'. The overall diameter is 7.0mm. It also differs from standard Cat5E construction in that it has two screens; a foil and a braid ("SF/UTP").
Note: For a more flexible cable with a single layer polyurethane jacket, see 31-890 CAT5E-F-R (this is a single screened F/UTP design and has an overall diameter of 6.0mm).
