This special indoor/outdoor drop cable with bend-insensitive fibre G.657.A2, protected by easy strippable soft tube, meets all requirements for FTTH access network: a small diameter, low weight, high tensile force and easily strippable features. The STAC-S is designed to connect the outside branch to customer’s termination box without splicing, resulting in reduced installation-time. This cable consist of a double jacket design, with a 90° bend radius inner subunit (STIC) perfectly suitable for indoor application, a robust outer sheath for outdoor installation and tensile strength members between both jackets. The outer sheath can be easily removed, when entering the building. Due to its (semi-)dry construction, this cable is highly safe and can be used in any human habitation. The dry soft tube makes also easier its installation into the vertical riser shafts of MDU’s. This multi-purpose cable can be installed by pulling in ducts, on external walls, or aerial between poles. The STAC-S cable is designed for maximum spans of 50m (NESC Light).
