It would be based on the amount of capacity each fibre in the overall 
system can carry across a given line system span.

So say a cable system is able to carry 960Gbps per fibre pair, and it 
has 5 fibre pairs, that means a half fibre pair purchased by one of the 
consortium members would be 480Gbps.

It is also possible for a consortium member to own a full + a fractional 
fibre pair, e.g., two and a-half fibre pairs. In such a contract, for 
example, say a 24 fibre-pair system could carry 1.2Tbps per fibre pair, 
that member would have 3Tbps of capacity.
