Further, the diameter of the central strength member (102) is in a range of 1.5 millimetres to 6 millimetres.

The present invention relates to an optical fiber cable (100, 200, 300) comprising one or more optical fibers (102), one or more buffer tubes (104), a first layer (106), a sheath (108), one or more embedded strength members (110), a plurality of water swellable yarns (112), a ripcord (114), a plurality of bundles of optical fibers (202) and a unitube (304). In particular, the core encloses the one or more optical fibers (102) encapsulated by one or more layers. Moreover, the sheath (108) encapsulates the core. Furthermore, the sheath (108) comprises one or more embedded strength members (110) coated with a hydrophobic material. Further, thickness of the hydrophobic material coating is in a range of 20 microns to 100 microns. Additionally, contact angle between water and the one or more coated embedded strength member (110) is equal to or more than 100 degrees.

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

The present disclosure relates to a fiber optic cable that includes a plurality of internal optical fibers and a fiber optic cable portion. The fiber optic cable portion includes an outer jacket and an inner conduit, the inner conduit containing the plurality of optical fibers disposed therein. The fiber optic cable further includes a flexible conduit portion, wherein the flexible conduit portion has a proximal end and a distal end. The proximal end is secured to the fiber optic cable portion and the distal end has a terminating device. The terminating device at least partially encases the flexible conduit portion, and the plurality of optical fibers passes through the flexible conduit portion and the terminating device.

Disclosed is an opto-electric cable including one or more electrical conductors. Each conductor includes an electrically conductive core and an electrically insulating layer surrounding it. The cable also includes an optical unit embedded within one of the electrically conductive cores. The optical unit includes at least two optical fibers and a single buffer jointly surrounding all the optical fibers. Each optical fiber includes a core, a cladding and a coating. Since all the optical fibers of the optical unit are jointly surrounded—and protected—by a single buffer, an optical unit with a reduced size is obtained. This allows reducing the cross section of the electrical conductor in which the optical unit is arranged. In particular, electrical conductors with cross section lower than 10 mm.sup.2 are obtained.
