FaultMapper
Cable Setup
The
Cable Setup
page allows you to set the
Cable
Type
,
Cable Length
, and
Cable Temperature
for the
FaultMapper test. All other
Cable Parameters
are read
only and correspond to the current cable book entry
as selected in
Setup
/
Cable Book
/
Cable Details
page.
These cable parameters affect distance calculations of
Capacitance
/
Opens
and
Resistance
measurements,
and the
TDR
cursor distance indication.
Cable Type
displays the ID, Cable Name and Fill,
and allows you to select an entry (with its
associated parameters) from the current Cable
Book, to use for testing. The selection is not saved
when leaving the test. The current Cable Book entry is shown by
default.
Cable Gauge
identifies the gauge system for measuring wire sizes, in
AWG (American Wire Gauge) units or mm (metric wire size).
Cable Fill
read-only entry is the type of material the cable is filled with:
Aircore
,
Jelly
,
Pulp
,
5 PR
, or
2 PR
.
Capacitance T-R
/
A-B
read-only entry is a value for the capacitance per
length constant used to calculate distance to opens.
Capacitance T/R to GND
/
A/B to E
read-only entry is a value for the
capacitance per length to ground constant.
Attenuation @ 300 kHz
read-only entry is a value in dB for the
reduction in signal strength or insertion loss of the cable at a frequency
of 300 kHz. (This frequency has been widely used as a loss
measurement for ADSL, but not validated for ADSL2+ nor VDSL2.)
VOP
read-only entry is the velocity of propagation for the cable defined
as m/
μ
sec (meters per microsecond), a ratio, or percentage of the
speed of light. Setup in the
Cable Book
, this value changes the
distance shown at the cursor.
