What are backbone cables?

As the term suggests with its anatomical name, the backbone forms the major core of network from which other elements can then branch off from. The backbone is the portion of the network cabling which connects across the various rooms and communication panels, carrying the largest number of fibres and normally constituting the longest cable run. Example backbone includes DeviceNet Thick cable.

Individual devices connect to the backbone through spur cables connecting to the main servers and devices and so enabling the exchange of data and information throughout the system or building. When the cable connects between buildings it is sometimes known as campus backbone cable.

Backbone Cable

The backbone cabling may be required to carry significant amounts of data and accommodate a large number of connections depending upon the size and complexity of the building. It’s not just computers and VOIP telephony systems but smart building systems that connect to this backbone so future expansions and developments should be considered when installing any network cabling, particularly the core backbone to the network.
