Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.

The present disclosure provides an intermittent tape (100) disposed of around a pair of conductors. The intermittent tape (100) has a top dielectric layer (102), a bottom dielectric layer (106) and a conductive layer (104). The conductive layer (104) is sandwiched between the top dielectric layer (102) and the bottom dielectric layer (106). The conductive layer (104) includes conductive segments (108) and non-conductive segments (110). The non-conductive segments (110) are defined by an absence of the conductive segments (108). The conductive segments (108) and the non-conductive segments (110) are arranged alternatingly. A width of the non-conductive segments (110) between the conductive segments (108) is constant.

The present disclosure relates to a cable (100) comprising at least one twisted pair of conductors (102) and a sheath (110) encapsulating the at least one twisted pair of conductors (102). In particular, the at least one twisted pair of conductors (102) has a pair lay length and a pair impedance. Moreover, the at least one twisted pair of conductors (102) has a frequency ratio between 4.77-12.25. Furthermore, the frequency ratio is ratio of the pair impedance to the pair lay length. Further, the cable (100) can operate between 0.1 MHz to 20 MHz. Additionally, the cable (100) is a Single-Pair Ethernet cable. The cable (100) further comprises an insulation layer (104) at least partially covering each conductor of the at least one twisted pair of conductors (102). Additionally, the length of the conductor is 105-115% of cable length.

Colorless twisted pair communication cables may include a plurality of twisted pairs of individually insulated conductors and a jacket formed around the plurality of twisted pairs. The cable may be formed to be completely free of colorant or to include a cable core defined by the jacket that is fee of colorant. Additionally, physical indicia may optionally be incorporated into the cable to facilitate identification of the plurality of twisted pairs.

Data/telecommunication cables that include one or more layers of an integral, bonded electromagnetic shield are described. The shield may be configured to form an electrical ground path.

A new dielectric material for a communication cable has a dielectric base with strength members embedded therein. By a new process, vacuum voids are formed in the dielectric base and at least partially contain or abut the strength members. The material is particularly well suited for a first dielectric tape, where the cable includes a first insulated conductor, the first dielectric tape and a second insulated conductor, with the first insulated conductor being twisted with the second insulated conductor with the first dielectric tape residing between the first insulated conductor and the second insulated conductor. The material is also suitable for a separator of the cable serving to separate twisted pairs from each other within the cable, as well as other components of the cable, such as an insulation layer of one or more of the insulated conductors of the twisted pairs.
