TRADITIONALLY, Reichle & De Massari
has a strong leading position in
technology for both shielded and
unshielded systems for data centres,
office cabling and fibre-optic
technology.
This makes it possible for the company
to offer professional, unbiased advice
to the customer to find the optimum
solution together, be it shielded or
unshielded, to last through several
generations of active equipment.
The newly introduced WAve Reduction
Pattern (WARP) technology is a prime
example. This accommodates the
demands placed on such systems by
the rapid uptake of 10GBase-T data
transmission.
Transmitting at 10 Gbit/s involves the
use of a sensitive, high frequency
coding method. The sampling rates
and the number of voltage values are
many times higher than for
1000Base-T. As a result, susceptibility
to interference increases by a factor of
100, due to the slight differences in
potential between input signals from
one bit level to the next.
This is caused by the rise in cable
attenuation at these high frequencies,
and by the increased coding. In order
for 10GBase-T to work correctly, it is
crucial to control and suppress
interference from outside the cables.
Innovative WARP technology
uniquely combines the superior
protection of shielded cable with the
convenience of unshielded cable. To
achieve this, the system is partially
‘shielded’ by adding short, isolated
sections of shielding (metal foil) to
the cable.
Because there is no continuous
shielding, it does not need to be
earthed. The length of each shielding
section is chosen so that no standing
waves can develop and produce
negative effects in the frequency
range up to 500MHz.
Used in system, WARP technology
allows ANEXT reserves that were
previously only possible with
shielding. This means there is no
need for follow-up measurements of
this parameter in the installation.
Measurements are guaranteed by the
layout of individual components.
WARP cables offer a further
advantage for Power over Ethernet
(PoE). The integrated aluminium foil
and thin cable sheath ensure heat
generated in this cable by power
transfer is lower than in comparable
traditional cables, reducing ageing of
plastic materials and allowing longer
cable runs.

WARP solution for unshielded
10GBase-T
OFS has launched its new SC crimp
and cleave connectivity solution for
industrial networks. The rapid adoption
of industrial ethernet has led to new
demands in factory automation and
industrial networking applications that
requires the introduction of
industrialised communications systems.
Fast (100Mb/sec) and Gigabit
(1,000Mb/sec) ethernet data rates
demand higher bandwidth and
real-time, low-latency communications.
The increasing use of intelligent
electronic devices, utility-grade rugged
IP routers, and ethernet switches is
driving a move to IP-based
communications on the production
floor.
A high bandwidth, rugged and reliable
cabling solution is essential for
industrial networking as increased data
rates are adopted. OFS is offering
graded index HCS® (GiHCS) optical
fibre in LSZH cable construction and
crimp and cleave SC connectors. Using
the SC crimp and cleave hand tools,
technicians can quickly install fibre
connectors in industrial spaces, and
rapidly repair damaged optical fibre
cables.
The advantages of the new SC
connectors are said to include a wide
operating temperature range (-20ºC to
+105ºC); abrasion, vibration and
chemical resistance; and high tensile
strength.
