BACKGROUND

[0002] Over the last few years, there has been an exponential growth in waveguide to the subscriber applications due to an increase in demand for high speeds and bandwidth. The waveguide to the subscriber applications requires a broadband optical waveguide distribution network. The optical waveguide distribution network includes optical waveguide distribution cables. Traditionally, aerial drop cables are desirable for use in the waveguide to the subscriber applications. These aerial drop cables form an external link between a distribution cable and the subscriber. These aerial drop cables are used for aerial installation and clamped on poles. Typically, these aerial drop cables include a number of cylindrical enclosure tubes inside a core of the optical waveguide cable, water swellable yarns and an outer jacket. In addition, these aerial drop cables include embedded robust components embedded inside the outer jacket. The embedded robust components may be made of brass coated steel wire.

[0003] The presently available aerial drop cables have several drawbacks. The aerial drop cables exert force on the poles on which the cables are clamped whenever any external load is applied on the cable. This leads to poles being broken and damaged which increases the maintenance cost. In addition, the prior art aerial drop cables do not allow easy access to waveguides. Further, the prior art aerial drop cables are not round in shape which does not allow the cables to be easily installed in ducts. The aerial drop cables cannot be blown or pulled easily inside the duct to a non-round shape.

[0004] In light of the above stated discussion, there is a need for an aerial drop optical waveguide cable which overcomes the disadvantages of the prior art aerial drop cables.
