Effective Shielding
The digital series features
highly effective braid,
foil, or serve shields, in
addition to the common-
mode rejection of the
balanced pair, that offer
protection from EMI & RF
interference that can
cause corruption to the
data bits or clocking
instability.

Precision Impedance
A 110S impedance-matched
interconnect system in high
data-rate, digital audio
applications is also critical in
order to minimize the occurrence
of standing waves within the
cable. Standing wave line
reflections, also known as return
loss, can cause both bit-errors and
jitter in the data stream and lead to
drop outs or degradation in the audio
signal.

Gepco AES/EBU twisted-pair cable is
constructed to an exacting and stable 110S
nominal characteristic impedance. This is
achieved by using a proportionate amount of low
k constant, foam dielectric material and special
non-conductive PE filler rods. In addition, the PE filler
rods maintain the geometrical configuration of the core
when the cable is bent or flexed, thus preserving the 110S
characteristic impedance.

Reduced High-Frequency Attenuation
In a digital audio signal, each sample consists of
a 32-bit word that is transmitted over the cable
interconnect as a series of rapid square wave
pulses. With excessive attenuation, the leading
edge of each pulse becomes “rounded” to the
point where the bit can no longer be recognized
as “on” or “off.” Because of this, minimizing
pulse-rounding in digital-audio data cable is
critical and requires a bandwidth of 128 times the
audio sample rate (e.g. 6.14MHz for 48kHz
stereo sample rates).

By lowering the capacitance of the cable, the data
pulse is significantly less rounded, thereby
enabling longer runs and more accurate data
transmission. To achieve this, Gepco AES/EBU
digital audio cable features either gas-injected
foam polyethylene, hard-cell foam polypropylene
or a foam FEP dielectric. All three compounds
have a low k constant that reduces the
capacitance and high-frequency absorption of the
insulation. In addition, the physical hardness and
melt temperature of these compounds are greater,
thereby minimizing the occurrence of accidental
nicking and insulation wick-back when soldering.
These attributes make the insulation not only
electrically superior, but also easier to prep and
terminate.
