The fiber optic cable is running on a dedicated line
Dedicated fiber internet works by running a direct fiber optic line from the service provider's network directly to a customer's building or suite. This line is not shared with other customers, which means the full capacity of the circuit is available at all times. Unlike shared networks that divide bandwidth and cause slowdowns, it guarantees consistent performance with symmetrical upload and download. With a dedicated line, you always get exactly what you pay for. The majority of standard internet services available in Delray Beach operate using cable or DSL lines, which serve many clients at different locations within the same area. Those differences can make or break a business fiber network.
