Abstract
A low fatigue rewindable optical fiber cable comprises a core having at least one optical transmission element, a dielectric armouring surrounding the core and a sheath surrounding the dielectric armouring. Particularly, the low fatigue rewindable optical fiber cable is characterized by a fatigue performance ratio (FPR) which is a ratio of a cross sectional area of the sheath and a cross sectional area of the dielectric armouring and is between 3 to 4.5 that enables at least 10 cyclic winds and unwinds carried out on a drum with a diameter of 40 times an outer diameter of the low fatigue rewindable optical fiber cable.
Claims17
A low fatigue rewindable optical fiber cable, comprising:
- a core formed by a tube having at least one optical transmission element, the at least one optical transmission element having a group of optical fiber ribbons that includes a number of optical fibers arranged together using a matrix material,
- a partially bonded optical fiber ribbon from the group of intermittently bonded optical fiber ribbons is formed, by intermittently bonding the plurality of optical fibers with the matrix material for imparting a bending and rolling capability along a width of the partially bonded optical fiber ribbon;
- a dielectric armouring surrounding the core, wherein the dielectric armouring having a plurality of strength members is arranged in helical fashion over the core wherein one or more strength members are in contact with each and each of the strength member has a diameter in a range of 1 mm (millimetre) to 1.2 mm;
- and
- a sheath surrounding the dielectric armouring.
