Data Communications Cable
Royle's considerable experience and expertise in foaming technology
has enabled the Company to be one of the recognized leaders in the
supply of sophisticated systems for manufacturing a wide range of
data communications cables. These coaxial cables comply with the
most stringent international standards including MIL, IEC, Bellcore,
RG, IBM, UL, CSA, ETL, and many others.
Royle offers several styles of extrusion systems to produce the
various types of data communications cables. Each of the systems
is customized to the customer's specific product needs and plant
requirements. The largest system in the data communications family
of lines is the RF/CATV line that is ideally suited to the manufacture
of highly expanded polyethylene constructions for high frequency
applications including Trunk CATV, Mobile Telephony, Radiating (Leaky)
Cables and Antenna Cables. Royle's Distribution & Drop CATV
line uses many of the same operating concepts as the RF/CATV line,
but the components are physically smaller and the operating speeds
are significantly higher.
Royle's freeFoam™ system has become the defacto industry standard
for the manufacture of fluoropolymer insulated LAN constructions
typified by the IBM Technical Interface Specification. The system
features a revolutionary process that produces a uniform cellular
construction without the use of physical or chemical ingredients.
All of Royle's data communications product offerings utilize proprietary
screw technology and automated control systems to ensure production
of high quality cables and repeatability of process conditions.
The manufacture of high frequency coaxial cables requires low SRL
(Structural Return Loss) and, therefore, the mechanical design of
the equipment must avoid repetitive frequencies called periodicities
which are often common in rotating devices such as pulleys, bearings,
transmissions, and rollers. Royle's design engineers have worked
closely with our coaxial cable process engineers to develop proven
systems for manufacturing coaxial cables with low SRL.
