to Gepco’s new gas injected dielectric and precision process control. The new dielectric
has a faster V.P., tight tolerance impedance, and low attenuation and structural return
loss across the entire 3 GHz bandwidth. Gepco’s proprietary process and compounds

Maximum Recommended Cable Lengths
Maximum values represent the
approximate range at which the bit
error rate “cliff region” will occur.
In every system the quality of the output pulse, the amount
of loss that can be compensated for by the receiver, the
number of passive connectors and patch points, and the
exact amount cable loss will vary. Because of this, the
exact maximum cable length possible will vary. The above
graphs do not represent the exact cable length possible,
they only serve as a guide in selecting the appropriate
cable type. When installing a cable in a system and it is
approaching its maximum range, it is highly recommended
that individual system testing and research be done.
