Cabling Recommendations
The tables in this section contain the maximum supported lobe lengths. The
maximum lengths reflect the longest lengths supported by the transmission
characteristics of IEEE 802.5-compliant adapters. The recommended distances for
the various cable types are set by North American and international commercial
building wiring standards. These standards state that standards-compliant
horizontal copper cabling shall not exceed 90 m (295 ft) leaving 10 m (33 ft) total
for required patch cabling in both the office and telecommunications closet. It is
good practice to follow the cabling standards guidelines when installing building
cabling to help ensure a longer useful life for your cabling infrastructure, migration
to new technologies, and maximum flexibility for the network configuration.
If you are installing new cabling for data applications, it is recommended that you
use the following types of cable:
Cable Type Impedance
Types 1 and 1A 150 Ohm
Types 2 and 2A 150 Ohm
Type 8 150 Ohm
Type 9 150 Ohm
Type 3 100 Ohm
Category 3 100 and 120 Ohm
Category 4 100 and 120 Ohm
Category 5 100 and 120 Ohm
