320 Series Selection Matrix (MDUs and Very Long Runs)
This is a quick reference for QR 320 Series cables from CommScope. Answer the questions as you read along the
diagram to arrive at the construction code for the cable required for your application.
QR 320 cables have a unique welded aluminum strip shield for superior RF protection and a large center conduc-
tor for lower attenuation over longer distances. We recommend them for use in MDUs.
Underground QR 320 cables use MigraHeal ® flooding compound which is applied under the jacket , making it
suitable for direct burial. MigraHeal floodant is designed to flow into damaged jacket areas, sealing this area and
inhibiting corrosion.
