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.
