Additional technical details
Fiber ribbons sit in a high-modulus loose tube filled with water-resistant compound. Coated steel tape is applied longitudinally around the tube, with parallel steel wires on either side and a UV-protective polyethylene sheath. Water blocking and gel protect the fibers, while the wires provide tensile and crush resistance. High fiber density aids installation, identification and maintenance. Applications include access networks, particularly FTTC and FTTB, interoffice links, CATV and building communications. Duct or aerial installation; −40 to +70 °C; bending radius 10 × diameter static and 20 × dynamic. The manufacturer states a service life above 30 years with controlled production and materials.
