What it is

gbn-shield

The Granta Backbone Network (GBN) is the collegiate University’s privately owned fibre network. It consists of a series of underground ducts, mounted cable tray and single mode fibre cables, which is used to distribute the numerous University and College IT networks around the city. The first phase of the network was finished in 1992 and measured around 35km, but today measures close to 85km.
