Category 7a cable with a model’s measurements

With its twisted-pair Uninet 7120 data cable, Dätwyler Cables has extended its range of Class FA systems by a very thin, high-quality PiMF cable (Pair in Metal Foil), meeting all the requirements for Category 7a (augmented). The Uninet 7120 has a copper wire diameter of only 0.58mm, corresponding to AWG 23. In combination with high-performance connectors, these comparatively economical high-speed cables can be used for up to 1,000 Megahertz (MHz), thus enabling them to transmit even applications such as 10Gbase-T (10 Gigabit Ethernet) without problems. “With our current innovation, we have succeeded in raising the Cat.7a quality to AWG 23 diameters for the first time”, explains Markus Grüter, head of market region 1 of Dätwyler Cables. “The high reserves of the Uninet 7120 provide long-term investment security with regard to future applications and upcoming data transmission rates,

but with far smaller space requirements and at an excellent cost/benefit ratio." When installing a Local Area Network (LAN) that must meet the requirements of Class EA (up to 500 MHz), AWG 23 data cables – and particularly those in Category 7 (up to 600 MHz) – are a popular choice.

At 1,000 MHz, the Uninet 7120 offers even higher reserves for the transmission of digital and analogue voice, image, multimedia and data signals in this range. In addition, its Cat.7a quality makes this an ideal cable for economical, space-saving, high-speed connections in computer centres. The new data cable has a FRNC/LSOH sheath, is 7.4mm thick and weighs only 63 kg/km, with a copper

count of 32.3 kg per km. At 1,000 MHz, its attenuation is less than 60 decibels (dB) and NEXT-value (near end crosstalk) is 90 dB. Dätwyler Cables – Switzerland Fax : +41 41 875 1986 Email : markus.grueter@daetwyler-cables.com Website : www.daetwyler-cables.com
