: Every cable, copper or fiber, must be labeled at both ends—typically within 12 inches of the termination point.

: Suggests standard colors for infrastructure types (e.g., Orange for demarc, Blue for horizontal, Purple for common equipment) to enhance troubleshooting .

: For multi-campus environments or global enterprises. It includes wide-area network (WAN) connections and inter-campus identifiers. Critical Implementation Areas Horizontal Link Identifiers

: Covers single-building facilities with multiple telecommunications spaces. It adds requirements for labeling backbone cabling and grounding/bonding systems.
