Abstract: The present disclosure provides an intermittently bonded optical fibre ribbon. The intermittently bonded optical fibre ribbon includes a plurality of optical fibres. The plurality of optical fibres are bonded intermittently along the length by a plurality of bonded portions spaced apart by a plurality of un-bonded portions. The plurality of bonded portions is defined by a bonded length Li and the plurality of un-bonded portions is defined by an un-bonded length. In addition, at least one of the bonded length Li and the un-bonded length varies along a predefined length of adjacent optical fibres of the plurality of optical fibres.

Abstract: A ribbed and grooved fiber cable (100) includes a core with a plurality of optical fibers, a sheath (102) enveloping the core and one or more strength members (108) embedded in the sheath (102). The strength members (108) are coated with a water blocking coating material having at least one of an ultraviolet (UV) curable water swellable resin composition and a layer of ethylene acrylic acid (EAA). Particularly, the water blocking coating material applied over the strength members (108) has a thickness of 50±10 microns. The sheath (102) of the cable (100) has at least one of a plurality of ribs (104) and grooves (106) on an external surface of the sheath (102), and a plurality of ribs (104a) and grooves (106a) on an internal surface of the sheath (102). The plurality of ribs (104) have variable height.
