Testing & measuring
Testing LAN, telecom,
umbilical and coaxial
cables
DCM provides test and measurement
solutions for quality assurance testing
of all types of twisted pair and coaxial
cables. Test parameters include crosstalk,
impedance, insertion loss (attenuation),
VSWR, capacitance, resistance, return loss
and SRL.
LAN cable test solutions covering Cat 5e,
Cat 6, augmented Cat 6 and Cat 7 cables
up to 1.5 GHz include:
Model SCS-350B bench-top system •
for Cat 5e and Cat 6 cables
Model CMS-2XLD integrated system •
for Cat 5e, Cat6A and Cat 7, including
6-around-1 alien crosstalk and power
sums
Model ES-2G bench-top system for •
Cat 7 cables
RF and coaxial cable test solutions cover
all types of coaxial cables for 50-ohm
and 75-ohm cables, for 3G to aerospace
applications. Test frequencies range from
3 GHz up to 40 GHz.
Telecom cable test solutions cover all
types of twisted pair telecom cables with
test fixtures up to 102 pairs. LF para-
meters include capacitance, resistance and
cable unbalances. HF parameters include
crosstalk and attenuation, as well as xDSL
applications up to 100 MHz.
Umbilical cable test solutions provide
measurements for offshore umbilical
cables and include automated testing of
all required electrical parameters on very
long cable lengths.

The unit can be combined with a vibrator element, a pressing system (up to 10,000N)
with up to three independent hydraulic pistons (adjustable for height and pressure),
an image analysis camera, chamfer control station, spring tester for load and/
or position measurement (up to 5,000N), and a sorting system with five
tolerance settings.

FMS Force Measuring Systems launches its newest RTM (radio transmitted tension
monitoring) system. Through continuous development work on the RTM System,
wire and cable manufacturers now have an affordable way to monitor and control
tension in individual wires on most planetary or tube stranders, bunchers, twisters, or
other rotating machinery. The RTM system monitors tension in real time on up to 32
individual strands, and can be configured to handle nearly any tension measurement
or control task. Actual tension values are displayed graphically on a PC monitor and
logged for possible quality assurance reference. The monitoring system is comprised of
tension sensors, tension measuring amplifiers, a bus system with radio transceivers, a
control unit and software.
In applications where closed loop tension control is desired, digital tension controllers
are integrated into the system. Controller parameters, including tension set points, can
be adjusted during machine operation. Possible configurations include the capability
to provide a high-/low-tension alarm signal, or an output to stop the machine
immediately in the case of a wire break. The FMS tension sensors are specially designed
for rotating applications, and are compensated for both centrifugal and Coriolis
forces to very high accelerations. A wide range of tension sensors is available to suit
almost any application. With the standard data logging feature, the RTM system will
record the tension value of each strand correlated to the product running length. The
RTM system is designed to be reliable, accurate, economical, easy to operate, and
virtually maintenance-free.
