Noob question - Fibre Optic Cables
Please can someone point me in the direction of a dummies guide to understanding fibre optic cables. We have a cabling guy who is putting in our new network fibre optics to link buildings and across one building.
He speaks of installing a 4 channel fibre optic but keeps asking about 65s or 157s or similar....
I get the basic of what a fibre optic is and how it works, the supposed unlimited bandwidth etc. The installation will be linking 3 HP switches in serial...
But, what is all the technical explanations for current cables etc please?
