Category 6 XS Cable

The XS™ cable is Hitachi’s new entry-level Category 6 cable. The XS cable is UL Verified, sweep tested to 555 MHz and delivers electrical performance that exceeds the ANSI/TIA 568.D-2 standard.

Made in the U.S.A. at Hitachi’s Manchester, New Hampshire facility, the XS cable includes a number of design features intended to speed installation while also maximizing shipping capabilities and warehouse space. The XS CMP (plenum) utilizes a smaller box than previous designs, thus enabling more efficient use of space for both shipping and storage. Changes to the CMR (riser) version are underway and their completion will be in the near future. The XS contains no center spline typically found in Category 6 cables. This fillerless design results in one of the smallest outside diameters available for a Category 6 cable. This small outside diameter also permits the highest conduit fill rates of all Proterial Category 6 cables and one of the highest in the industry. The XS pulls smooth from the Reelex box and lays flat when dispensed. These characteristics enhance the installer experience by offering easier and faster pulls during installation. Its 24 AWG conductors help in limiting its outside diameter while also supporting Power over Ethernet applications such as the popular IEEE 802.3 af and at and the more demanding IEEE 802.3bt. It is also Hitachi’s greenest cable. It utilizes a brown box of 100% recycled cardboard for both CMP and CMR cables. This product package, since it has no chemical or waxy coatings, requires less resources to enter the recycle stream. It’s fillerless design also requires less materials than those with fillers and almost all of the materials used in its construction are from New England or northeast based companies.

Like all of Hitachi’s indoor Category 6 cables, the XS cable is eligible for our Lifetime product and performance warranty. The XS is available in a wide range of colors.
