AFAIK Gemini is a 48 pair fibre ring. Initially it will be run without
Wave Division Multiplexing, so using the most boring of boring kit that's
48 x 2.4Gb = 115Gb. However it's not too hard these days to get 4.8
Gb down a fibre without WDM, and WDM could give up to a 16x increase
(cable is built for WDM just no point deploying it initially). This
would give 7360Gb. Alledgedly technolody that supports this is "in the labs".
