How much spectrum is a half fibre? It must be standardized in
some fashion.
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.
