QR 320 Series Cables
Product Descriptions
CommScope’s patented QR® coaxial cable was developed to meet the increasing demands of tomorrow’s broadband
networks. QR has the highest reliability and flexibility of any Trunk and Distribution coaxial cable, low RF attenuation
and an unprecedented 10 year warranty.
All QR cable products offer tough polyethylene jackets and a standardized, environmentally sealed connector
interface engineered for reliability and craft friendliness.
QR 320 is optimized for use in multiple dwelling units (MDU) and feeder applications. QR 320 offers unmatched
flexibility, reliability and cost effectiveness.
Standard QR Construction
A precision aluminum strip is formed and continuously RF welded around a high compression micro-cellular foam
dielectric core, eliminating RF leakage, and the rigidity common in traditional coaxial products. The shield is fully
bonded to the dielectric core, as is the copper clad aluminum center conductor. A tough polyethylene jacket is
applied standard, which enhances cable reliability and allows QR’s unique connector technology to form an environ-
mental seal.
