Since many enterprises' storage components are located across greater distances, the servers are
connected through single-mode cabling.

Using Infrastructure Cabling

Infrastructure cabling (or cable plant) refers to the complete cabling system within a building or
buildings. This section discusses of infrastructure cabling and includes a scenario in which an
RA4000 uses infrastructure cabling to connect across multiple floors. This example should help
answer the questions:
Is the existing infrastructure cabling useable?
Does new infrastructure cabling need to be installed?
If new infrastructure cabling is needed, what type should be installed?
