The present invention relates to an optical fibre cable () and the method of manufacturing thereof. In particular, the optical fibre cable () comprises a plurality of optical fibres (), one or more layers () enveloping the plurality of optical fibres (), a metallic layer () surrounding one or more layers (), an outer sheath (), and a separation layer () sandwiched between the metallic layer () and the outer sheath (). Particularly, binding between the metallic layer () and the separation layer () is defined as metal binding and binding between the separation layer () and the outer sheath () is defined as sheath binding. Further, the metal binding is less than the sheath binding.

Unbonded armored optical fibre cable

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 Land the plurality of un-bonded portions is defined by an un-bonded length. In addition, at least one of the bonded length Land the un-bonded length varies along a predefined length of adjacent optical fibres of the plurality of optical fibres.

Intermittently bonded optical fibre ribbon with unequal bond and gap lengths

A strength member () for use in an optical fiber cable () and manufacturing method thereof. The strength member comprises a plurality of reinforced yarns and one or more layers of epoxy resin over the plurality of reinforced yarns, wherein the one or more layers of epoxy resin have a modified surface such that a strength member friction coefficient is between 0.3 to 0.5. The strength member friction coefficient is measured between a surface of a sheath () of the optical fiber cable and the modified surface of the one or more layers of epoxy resin. The one or more layers of epoxy resin are blended with at least one of sand crystals and silicon dioxide powder, wherein concentration of the sand crystals or the silicon dioxide powder in the one or more layers of epoxy resin is 50 to 100 phr (Parts-per-Hundred-Resin).
