Building and Campus Backbone Cabling

IBM 8265: Planning and Site Preparation Guide
IBM supports the use of both multimode and singlemode optical fiber in building and
campus backbone applications. Not all applications are supported on singlemode and
multimode optical fiber. IBM products are designed to operate on cables and
connectors as specified in both emerging cabling standards. Other cables and
connectors are also supported, but support may be at reduced distances. Copper
cabling, both 150-ohm STP or STP-A, and Category 5 UTP may be appropriate,
generally, for inter-telecommunications closet distances not exceeding 90 meters, and
within a single building. However, this copper cabling should be a supplement to, and
not a substitute for, the recommended optical fiber cable interconnecting the
telecommunications closets in a campus network.
