Looking for the best Business Fiber Internet providers in Pittsburgh, Pennsylvania? Here's your ultimate guide to making an informed choice.
What is Business Fiber Internet?
Business Fiber Internet refers to high-speed internet connectivity delivered over fiber optic cables, specifically tailored for business use. It is considered the 'gold standard' for business internet, offering high-speed throughput with consistency over long distances. Businesses can choose between 'best effort' fiber, which is shared with others, and 'dedicated fiber,' which ensures consistent performance by not being shared.
Business Fiber Internet providers are also location-based, as their services depend on the availability of specific network infrastructure in a given area. The feasibility, cost, and installation time for fiber service are determined by whether the provider's network is already present ('on net'), nearby ('near net'), or requires a new buildout ('off net').
