Section 5.1.2 States

A horizontal link identifier, unique within the building, shall be assigned to each horizontal link and to its elements.

Each end of a horizontal cable shall be labeled within 300mm (12 inches) of the end of the cable jacket with the

horizontal link identifier, which shall be visible on the exposed part of the cable jacket. This shall include each

cable in the Telecommunications Space (TS), at the work area, and at a Consolidation Point (CP), if present.

A horizontal link identifier shall have a format of “fs-an” where:

f =

numeric character(s) identifying the floor of the building occupied by the TS

s =

alpha character(s) uniquely identifying the TS on floor f, or the building area in which the space

is located

a =

one to two alpha characters uniquely identifying a single patch panel or a group of patch panels with

sequentially numbered ports, an IDC connector or a group of IDC connectors serving as part of the

horizontal cross-connect

n =

two to four numeric characters designating the port on a patch panel in the TS or the section of an

IDC Connector on which a four pair horizontal cable is terminated in the TS

For example:

“1A-B01” = cable origination point first

floor, TS A, patch panel B, position 01

Section 6.1.1 States

A unique building backbone cable identifier shall be assigned to each backbone cable between two TS’s in one

building and it shall have a format of “fs1/fs2-n” where:

fs1 = TS identifier for the space containing the termination of one end of the backbone cable

fs2 = TS identifier for the space containing the termination of the other end of the backbone cable

n = one to two alphanumeric characters identifying a single cable with one end terminated in the TS

designated fs1 and the other end terminated in the TS designated fs2

In this format, the TS with the lesser alphanumeric identifier shall be listed first. If the entire cable is within one

TS, the format may be fs1/fs1-n. All building backbone cable identifiers in a single infrastructure should have the

same format where possible. The backbone cable identifier shall be marked on each end of the backbone cable

within 300mm (12 inches) of the end of the cable jacket.

For example:

“1A/2A-1” = TS A on first floor to TS A

on second floor, cable 1

Panduit labels for laser/ink jet printers and hand-held thermal transfer printers can be

generated by a mechanical device and are made of durable polymer construction that will

withstand the effects of moisture, heat, and time.
