SABRENet is a fibre-optic broadband network linking major Research & Education sites in metropolitan Adelaide, South Australia.
How big/fast/long is SABRENet?
SABRENet comprises over 100km of optical fibre cable running in underground conduit.
Each cable contains between 72 and 354 optical fibres, which are generally used in pairs.
Each pair of fibres can, if required, transmit hundreds of gigabits per second (Gbps). To give an idea of the capacity of optical fibres, researchers at IBM have calculated [1] that if every telephone subscriber in the US made a call at the same time, the entire load could be carried on just three fibre pairs using today's equipment.
In practice however, it is generally easier and (once the fibre is installed) much cheaper to use multiple fibre pairs at less than thier maximum capacity.
SABRENet fibre pairs are currently used to run 10Gbps and 1 Gbps ethernet services.
