cords. CCA conductors are not permitted in any
of these standards.
Any manufacturer using CCA and claiming
conformance to these standards, or claims to
have third party verification for their cables
is making false statements and should be
avoided.
Performance
As well as not conforming to national and
international standards, cables that contain
CCA will also fall short on electrical and
installation performance. It is commonly
believed that CCA conductors have high
frequency and electrical properties that are
the same as solid copper conductors. As
CCA has the copper layer on the outer of the
conductor, this means the performance at the
higher frequencies may be similar but at lower
frequencies and for DC current parameters the
performance is degraded.
Comparative ISO11801 Class D permanent link
performance of CCA v solid copper conductors.
Aluminium has a much higher resistance
than copper. This will mean cables using CCA
conductors will fail permanent link testing,
especially for lengths over about 80m.
CCA also has a higher attenuation than copper,
which will have a noticeable effect on longer
channel lengths and it will lead to network
problems for users

R&M to launch highdensity fibre management
solution
R&M has announced the
Middle East launch of
Netscale, the highest-density
fibre cable management
solution, and the first to
feature integrated intelligent
infrastructure management
functionality. Designed as an
ultra-high density platform
that utilises the smallest diameter uniboot patch cord for minimal
cabling bulk, this solution boasts up to 67% higher density
than its competitors and promises to eliminate a host of cable
management problems that plague data centres today.
The rapid growth in the volume of data being stored and
managed in data centres in recent years has raised a clear need
to realise maximum port density in the smallest space possible.
However, increasing density often results in unmanageable
cabling, which makes Moves, Adds and Changes (MACs), cable
tracking and fault-finding impossible.R&M has specifically designed
its new solution keeping these challenges in mind.
“Netscale is the next generation fibre optic solution, based on
the quality and reliability for which the R&M brand is renowned,”
states Dr. Thomas Wellinger, Market Manager Data Centre, R&M.
“It’s combination of market leading features saves considerable
amounts of costly space at large companies in the financial,
pharma, colocation and telecom segments as well as edge data
centres. In addition, the solution offers a lower cost per port
than existing platforms, and provides a flexible upgrade path to
accommodate needs for many years to come.”
Currently available high-density fibre solutions for data centres
generally offer up to 72 LC duplex ports per rack unit and pose
great difficulties for management. Thanks to R&MinteliPhy
technology, Netscale delivers a density of up to 80 RFID-monitored
LC duplex or MTP ports, and even 120 standard LC duplex or
MTP ports per rack unit. The innovative rear-cabling manager
makes it truly easy to manage connections, alleviating risk during
MACs and migrations. Modular components and best-in-class
network scalability makes it possible to accommodate the unique
infrastructure requirements of each data centre.
