The interbuilding backbone fiber optic cabling is the part of a fiber optic network that provides the designer with the most flexible options. However it is also the most constrained by duct availability, right-of-way and other physical barriers.
The interbuilding backbone fiber cables must provide some basic characteristics provided its critical application environment. The following list is not exhaustive at all but a minimum requirement.
- Offers excellent attenuation performance over a wide range of temperatures
- Sufficiently strong to endure the rigors of installation
- Its sheath should provide protection against ultraviolet radiation
- Its sheath should provide protection against gnawing rodents and other mechanical disturbances
- The cable should have a high packing density to maximize the use of available installation spaces
