Insertion Loss

Insertion loss is also known as attenuation.
Insertion loss is the loss of signal strength over the cabling,
as shown in Figure 3-14. Insertion loss is caused by the
resistance of the copper wire and connecting hardware and
by leakage of electrical energy through the cable's
insulation.

Note
Figure 3-14. Insertion Loss is a Decrease in Signal Strength
At higher frequencies, signals tend to travel only near the
surface of a conductor. This "skin effect", along with the
cabling's inductance and capacitance, cause insertion loss to
increase with frequency.
Figure 3-15 describes the insertion loss plot.
