Every segment of fiber is managed by an Optical Line Terminal (OLT) that oversees the data traffic. From one terminal, 15 miles of fiber can be served in any one linear direction. For example, this means if an OLT was placed at a 4-way intersection, 60 miles could be served from one OLT, but on average our OLTs serve 20-25 miles. Multiple OLT Segments can be spliced together to expand the network further and further to create one large network over hundreds or thousands of miles.
