This application claims the benefit of Indian Application No. 202111011037 titled “TELECOMMUNICATION CABLE WITH TAPE” filed by the applicant on Mar. 11, 2022, which is incorporated herein by reference in its entirety.
Embodiments of the present invention relate to the field of telecommunication cables and more particularly, relate to a telecommunication cable with tape for high speed data transmission.
Telecommunication cables are ubiquitous and used for distributing all manner of data across vast networks. The majority of cables are electrically conductive cables (typically copper), although the use of optical fiber cables is growing rapidly in telecommunication systems as larger and larger amounts of data are transmitted. Additionally, as data transmissions increase, the fiber optic network is being extended closer to the end user which can be a premises, business, or a private residence.
In a telecommunication cable, data propagates via twisted pair conductors. A conventional twisted pair conductor generally includes two insulated conductors twisted together along a longitudinal axis of the telecommunication cable. The performance of the telecommunication cables having twisted pair conductors is evaluated utilizing parameters like impedance, return loss, propagation delay, attenuation, cross-talk and the like.
Currently, various types and configurations of the telecommunication cable exist. One of the types and configurations includes the telecommunication cable with a tape. Conventionally available telecommunication cables with tape have higher mutual capacitance for specific twisted pairs of conductors. Generally, mutual capacitance is an ability to hold a charge between two adjacent conductors. The specific twisted pair of conductors is a pair that causes the higher mutual capacitance when they come in contact with the tape. To stabilize the mutual capacitance of the specific twisted pair, it is necessary to distant the tape from the specific twisted pair. As a general practice, the insulation thickness of conductors forming the specific twisted pair is increased so that the specific twisted pair is distant from the tape.
Although increasing thickness stabilizes the mutual capacitance, it results in higher propagation delay in the telecommunication cable. Additionally, increasing the thickness of insulation makes the telecommunication cable bulky and costly. Therefore, it is necessary to employ some technique to compensate for the negative effects of propagation delay and mutual capacitance. Currently, there are a few patent applications that provide telecommunication cables with tape.
U.S. Pat. No. 10,232,833B2 titled “Method for operating a brake control system for a rail vehicle comprising a brake system, brake control system, brake system, and rail vehicle” discloses placing shield/tape with two methods. The methods include a fixed tape control method to control the position of the tape overlapping over any one twisted pair and it is fixed thought-out the length of the cable.
U.S. Pat. No. 5,939,668A titled “Patch cable” discloses overlapping of two shields/tapes over the core of the cable. In particular, the overlapping is over the core at two different positions and does not mutually cross each other.
U.S. Pat. No. 10,008,307B1 titled “High frequency shielded communications cables” discloses a cable which has an overall shield covering the core of the cable. In particular, the overlapping is not fixed and can be over any one of the pair of the cable.
US Patent Application Publ. No. 2014262411A1 titled “Extended curl s-shield” discloses a cable with tape separator and shield covering the core of the cable. In particular, the shield has an overlapping section over one of the twisted pairs.
However, there are a number of drawbacks in the current technologies providing telecommunication cables with tape. Conventional solutions provided in the prior arts do not provide controlled overlapping over the specific twisted pair. Moreover, the prior arts also do not disclose technique or arrangement enabling a controlled overlapping of the tape over the specific twisted pair. Due to controlled overlapping of the tape over the specific twisted pair, the tape may be placed distant from the specific twisted pair.

The following brief definition of terms shall apply throughout the present invention:
Communication cable consists of copper conductor surrounded by insulation.
AWG is a standardized wire gauge system. In particular, the value of the wire gauge indicates the diameter of the conductors in the cable.
Overlapping is when at least a small part of a tape covers at least a small part of the same tape over a specific twisted pair.
Propagation delay is a measure of time required for a signal to propagate from one end to other of the telecommunication cable. In particular, propagation delay is defined as the flight time of packets over the transmission link. Moreover, propagation delay is the amount of time it takes for the head of the signal to travel from the sender to the receiver. It may be computed as the ratio between the link length and the propagation speed over the specific medium. If the propagation delay is higher, propagation margin is low with respect to the margin defined in the ISO IEC 11801/ANSI-TIA 568 D standard. This increases the latency in the cable and decreases the speed of the signal. However, if the propagation delay is lower then, the propagation margin may be higher with respect to the margin defined in the standard. This may decrease the latency and increase the speed of the signal. Furthermore, both scenarios may make the cable non-compliant with the defined ISO IEC 11801/ANSI-TIA 568 D standard.
Crosstalk is electromagnetic interference produced from one non-shielded twisted pair to another twisted pair, normally running in parallel.
Lay length is the length between the different twist over the twisted pair.
Plurality of characteristics comprises electrical properties and transmission characteristics. In particular, electrical properties include input impedance, conductor resistance, mutual capacitance, resistance unbalance, capacitance unbalance, propagation delay and delay skew. Moreover, transmission characteristics include attenuation, return loss, near end crosstalk, attenuation to crosstalk ratio far end, alien cross talk, power sum attenuation to crosstalk ratio at far end, transverse conversion loss and power sum alien near end cross talk.
Capacitance unbalance is the difference in capacitance between the four conductors of two pairs of twisted insulated conductors. Any difference in the twisted insulated conductor diameter, the insulation thickness, uneven twisting of one or both pairs among the four conductors may result in pair-to-pair capacitance unbalance. Similarly, the lay length and proximity of the two pairs may also affect the capacitance unbalance pair-to-pair. According to ANSI/TIA-568-D & ISO/IEC 11801 Ed. 2.0, to stabilize the capacitance unbalance, the value of capacitance unbalance may be below 160 pF/100 m and the value of mutual capacitance should be below 5.6 nF/100 m.
Attenuation is reduction in strength of a signal travelling through the telecommunication cable 100. The crosstalk may be the near end cross talk, alien cross talk or the like. Moreover, the near end crosstalk is an error condition describing the occurrence of a signal from one wire pair radiating to and interfering with the signal of another wire pair. Similarly, the alien crosstalk is electromagnetic noise occurring in a telecommunication cable 100 running alongside one or more other signal-carrying cables.
Alien refers to alien crosstalk occurring between different cables in a group or bundle and not between individual wires or circuits within a single cable.
Terms “insulation layer 112” or “insulators 112” or “protective coating layer 112” are interchangeably used throughout the draft for convenience.

Moreover, the plurality of twisted pairs 102, the at least one tape 104 and the separator 108 is further passed through the bunching unit 606 to form the bunched core 120. Furthermore, the plurality of twisted pairs 102 along with the separator 108 forms the core of the telecommunication cable 100.
