US Patent 10249410 Power over ethernet twisted pair communication cables

A communication cable suitable for Power over Ethernet applications may include a jacket that defines a cable core and a plurality of twisted pairs of conductors disposed within the cable core. Each of the conductors may have a diameter of at least approximately 0.0240 inches or the equivalent of a 22 American Wire Gauge conductor. Additionally, each of the plurality of twisted pairs may have a different twist lay, and the respective twist lays may be selected such that the communications cable satisfies the requirements of a Category 6A cabling standard. The communications cable may have a delay skew of less than approximately 45 nanoseconds per 100 meters and a direct current resistance unbalance between pairs of less than approximately 100 milliohms per 100 meters.
