What it is

gbn-shield

The Granta Backbone Network (GBN) is the collegiate University’s privately owned optical fibre network. It consists of a series of underground ducts, mounted cable tray and optical fibre cables, which is used to distribute the numerous University and College IT networks around the University’s city campuses. The first phase of the network was finished in 1992 and measured around 35 kms, but today measures close to 60kms.
