CommScope Drop Cable - Manual (Page 5)

How to Use This Guide
The Drop Cable Applications and Construction Guide is written for the cable installation professional who, due to
the diverse services offered by CATV and telecommunication service providers, needs a quick and handy reference
to practical installation information, especially in the case of retrofitting.
We’ve tried to simplify the decision-making process as to which cables to choose for what installation, taking into
account factors such as performance over distance, preventing RF interference and fire/safety codes.
We also want to introduce you to some products that may ease some of your installation headaches, such as
BrightWire ® anti-corrosion treatment for braid shields, and QR ® 320, an ultra-long reach coaxial cable.
One of the big changes in our industry is the introduction of powered broadband services, which are addressed in
the National Electrical Code’s Article 830. This manual shows you when to use NEC 830 cables; sections 6 and
7 cover specific issues involving installation clearances; other chapters carry special callouts concerning NEC 830
issues.
Most attention is paid to residential installations (section 9) which has the most ‘practical’ information, especially
for trim-out. Sections 10 and 11 (MDU and commercial installations) are more general, and will refer you back to
section 9 for the specifics of finishing out the installation.
It is impossible to cover every single situation an installer may run into. These guidelines are no replacement for
your good common sense and experience.
It’s always good to know that you have backup should you run into a difficult installation. If you find you need
advice, call CommScope’s BRC (Broadband Resource Center TM ) toll free at 866-333-3272 from
9 am to 5 pm ET Monday through Friday. We’re always glad to help out a fellow professional.
