Cape Town fibre trial hits 400Gbps download speed

The Mother City may be in danger of losing its capital status if Parliament decides to shift “oop north” (as we say where I come from), but it’s just put in a claim to the throne of Queen of Broadband connectivity. Tests on the Cape Town metro fibre network just proved that it’s capable of sustaining data transfer speeds of 400Gbps, while doing something else.

Telecoms firm ADVA Optical Networking apparently carried out the tests, according to a press statement just received at htxt.towers, sending bits around a 106km route between Nyanga and Mitchells Plain. It says that it tested switching speeds of 200, 300 and 400Gbps on the network while multiple 10Gbps signals were still live.

The metro fibre network is currently used to connect 300 government buildings and 190 hotspots as well as commercial services.

According to Mayoral Committee Member for Corporate Services and Compliance, Councillor Xanthea Limberg, “The trial demonstrates a potential quantum leap in both the speed and the potential performance of our network. At 400Gbps, it takes less than 0.02 seconds to transfer data equivalent to the capacity of a movie.”

By happy coincidence, assuming an average movie is an hour and a half long, it would take just under one second to download all 97 episodes of Quantum Leap using Councillor Limberg’s maths too.
