DC and AC attenuation over long distances. Figure 14a
shows a 1
μ
s pulse propagated down 4000 feet of category
5 UTP. Notice the significant attenuation at the receiver
input and the clean pulse at the receiver output. The DC
attenuation is due to the parasitic resistance of the cable.
Figure 14b shows a 1Mbps square wave over the same
4000 feet of cable.

Category 5 UTP Using Repeaters
The LTC1686/LTC1687 can be used as repeaters to extend
the effective length of a high speed twisted-pair line. Figure
15a shows a three repeater configuration using 2000 feet
segments of category 5 UTP. Figure 15b shows the
