Loop loss per kft for other wire is summarized in
Table 6
. Recommended maximum local loop loss
information for PIC cable at 70ºF, 135
Ω
resistive
termination is provided in
Table 7
.
NOTE
These approximations are to be used as guidelines
only and may vary slightly on different loops.
Adhering to the guidelines should produce
performance in excess of 10-7 BER.
