What is fiber optic backbone used for?
The fiber optic backbone can mean different things depending on the service being used. Generally, however, it simple refers to that fiber optic cable traversing the main path or route in that part of the overall network. It differs with a lateral, which would run from a backbone splice point to typically an end use premise (ie building or cell site). Backbone cables will typically be built with high fiber counts and laterals will have relatively fewer fibers in the cable since it will have less use.
