[0001] The present disclosure, relates to the field of
telecommunication cables. More particularly, the present disclosure relates to a notched conductor for a twisted pair telecommunication cable.
BACKGROUND
[0002] With an increase in utilization of complex communication and networking systems, the demand for transmitting signals at high transmission rates has increased. In order to meet the growing demands, various types of telecommunication cables are used for transmitting signals which are compliant with high-performance data standards. These telecommunication cables are classified into Category 5, Category 6 and Category 7 based on the signal transmission characteristics. Also, these telecommunication cables are classified into UTP (Unshielded Twisted Pair) cables, FTP (Foiled Twisted Pair) cables and STP (Shielded Twisted Pair) cables based on the shielding. Among these, a telecommunication cable is the widely used telecommunication cable in which one or more twisted pairs of insulated conductors are bundled within an outer jacket.
[0003] The telecommunication cable has one or more signal
transmission and loss characteristics like insertion loss, return loss, propagation delay and input impedance. Out of these, the insertion loss is one of the major characteristics of the telecommunication cable. The insertion loss measures an amount of energy lost as the signal is transmitted across the telecommunication cable. The insertion loss of the telecommunication cable increases with the frequency of the signal

to be transmitted. In addition, the insertion loss in the telecommunication cables occurs majorly due to skin effect. In general, the skin effect is the tendency of an electric current to distribute itself within a conductor so that the electric current density near the conductor's surface is greater than that at its core. The skin effect causes an effective resistance of the conductor to increase with the frequency of the electric current resulting in high insertion loss. Presently, several attempts are made to deal with the skin effect. One such attempt involves plating of the conductor with noble metals. Another such attempt involves an increment in cross-sectional diameter of the conductor for providing a larger surface area over which the electric current can flow. However, these attempts have several drawbacks. These attempts are expensive. In addition, these attempts produce bulky cables with low effective conductor area utilization at the high frequency. Moreover, these attempts are unable to make efficient use of the conductor.
[0004] In light of the above stated discussion, there exists a need for a
telecommunications cable which overcomes the above cited drawbacks of conventionally known telecommunications cable.
