Cabling Terms

This chapter identiﬁes and deﬁnes several terms that are used throughout the text of this manual.

The following terms and deﬁnitions deal with the physical makeup of cabling

used in Local Area Networks.

Media refers to a type or family of cables. When the term media is used, it

indicates a type of cabling, rather than a speciﬁc cable. A reference to "ﬁber optic

media" deals with the characteristics of all ﬁber optic cable types, such as single

or multimode ﬁber optics.

The term cable, as used in this document, indicates either a speciﬁc type of

transmission media (i.e., multimode ﬁber optic cable) or indicates a physical

section of that media (i.e., "the installed cable must be no longer than 200 m").

Facility Cabling

Facility cabling, sometimes referred to as building cable or horizontal cable, is the

network cabling that is installed in a building or ofﬁce. It only includes the actual

wires that are placed within the walls, conduits, or speciﬁc cable channels of the

building. The majority of cabling used in a network installation is facility cabling.
