Fiber internet is a type of broadband connection, similar to the traditional DSL and cable. Like a landline telephone, DSL transmits data using electricity over copper or cable wires. Cable internet uses coaxial cables. Both of these transmission methods can make your internet connection more prone to intermittent outages due to weather, distance or even electromagnetic interference.
Fiber internet sends data using light that passes through glass tubing, known as fiber-optic cables, which are less susceptible to outside interference. This allows for the fastest internet speeds with the most reliable connection yet.
