What is the difference between ADSL and IFITL?
Asymmetric Digital Subscriber Line (ADSL) and Integrated Fiber in the Loop (IFITL) are two different technologies used to provide you with DSL service. Depending on the type of telephone cables in your neighborhood, your DSL Internet service will utilize either an ADSL connection (in the event of copper telephone lines) or an IFITL connection (in the event of fiber optic telephone lines). The two are identical in terms of connection speed.
