CommScope Trunk & Distribution Cable - Manual (Page 52)

There is an operating range, though, in between these two extremes of performance that facilitates a dielectric
bond that will cleanly break away from the center conductor without sacrificing the mechanical aspects of the cable.
CommScope has developed, ACT (Advanced Coring
Technology), a patent-pending bonding technology that
operates in this window between the extremes. As shown in
the chart in Figure 1, it exceeds the SCTE requirements for
bond strength and provides for a clean and easy removal of
the bonding material.
With this technology, the force exerted by the coring tool is
sufficient to cause the dielectric to break away from the center
conductor, leaving a clean conductor that typically does not
require a second dielectric removal step. The tool and the
craftsman can influence this enhanced performance
characteristic of the cable, making a one step coring highly
repeatable.
In addition to bond strength, the bonding agent also
maintains the other key performance criteria of the cable as
called out in the SCTE specification. Some of those criteria are
listed in Table 1.
Overall this solution provides all of the benefits of water
migration deterrence, corrosion prevention, and mechanical
performance while eliminating the performance risks
associated with center conductor dielectric removal.
Summary
The bond strength in cable is critical to the mechanical
performance of the cable. However, bonding affects more than
just the cable’s mechanical characteristics, it also impacts the facilitation of cable preparation and
connectorization. Finding the balance of bond strength and craft friendliness is accomplished by the development of an
advanced technology bonding agent and coupling it with CommScope’s consistent manufacturing process controls.
This achievement enables the cable to mechanically behave the way it needs to and makes the preparation easier.
