Color codes for cross-connections fields have been used for many years. Which color is used to identify horizontal cable?

Blue is the designated color for horizontal cable connections per the ANSI/TIA-606 administration standard. This color coding enables technicians to quickly identify cable roles at cross-connect fields, distinguishing horizontal runs from backbone, outside plant, and equipment connections.

Green identifies connections to network access equipment or outside plant cable, not horizontal cable.

Purple identifies connections from common equipment such as PBX systems or other shared telecommunications equipment.

Orange identifies the demarcation point or central office connections, not horizontal cable.

Brown identifies interbuilding backbone cabling, not horizontal distribution cable.
