We put 4 cables down each conduit or duct whatever you want to call them.
Each cable contains 12 smaller cables containing another 12 multimode
fibres. So in each conduit we have 4*12*12 multimode fibres. This is a lot
of Bandwidth and also the reason the city started the excess bandwidth scare
mongering a few months ago without actually looking at how much these things
cost to lay.
