What Is Fiber Internet and How Does It Work?

Lectura de 3:00 minutos

Fiber Internet uses light to transmit data instead of electricity, meaning it can transmit data fast and efficiently.

A typical fiber-powered network includes:

Fiber-optic cables that carry data via light-based signals
Network nodes and terminals that manage traffic flow
Converters that translate light signals into data your devices can use

There are two main types of fiber networks: fiber to the home (FTTH) and fiber to the node (FTTN). FTTH runs a fiber connection directly to each home, while FTTN delivers fiber to a neighborhood node and then completes the connection to an individual home via hybrid fiber coaxial network (HFC).

What Are the Benefits of Fiber Internet?

Every online activity depends on how quickly and efficiently data moves. We expect our Internet to be fast, despite more connected devices simultaneously running bandwidth-intensive activities such as video calls, cloud gaming and 4K streaming.

Fiber Internet is built to meet those demands. It delivers fast, reliable speed with low latency. By transmitting data as pulses of light through ultra-thin optical fiber strands, fiber is the foundation for excellent connectivity.

Does Spectrum Offer Fiber Internet?

Yes – in fact, Spectrum offers two different fiber Internet products. One offering is 100% fiber, connecting medium and large businesses as well as select residential areas. The other is a fiber-powered service that delivers Internet using advanced fiber technology via HFC – a hybrid fiber-coaxial network – to homes and small businesses.

What Is Fiber-Powered Internet for Homes?

When you sign up for a Spectrum Internet plan, your home is connected via Spectrum’s fiber-powered HFC network – powered by fiber and connected to the premises via coaxial cable. That means fiber cables carry data across the core network, while coaxial cable completes the final connection to your home. Using existing cables already connected to your home eliminates the hassle of a full fiber installation, meaning you can enjoy fast, reliable Internet the same day.

With Spectrum fiber-powered Internet, you can:

Stream and game across multiple devices without buffering
Stay productive with reliable connections for remote work or school
Enjoy Gig speeds everywhere and up to 2 Gig speeds in select areas

Select residential areas are eligible to receive Spectrum's 100% fiber product where available.

What Is 100% Fiber Internet for Businesses?

Spectrum offers a Dedicated Fiber Internet product for medium to large businesses, which provides a full fiber infrastructure all the way from the network hub to the office. This dedicated Internet access is an Internet connection that serves a single customer, rather than serving multiple customers. This allows a business to have Internet access with guaranteed levels of bandwidth and speed even during peak hours, instead of competing with others for connectivity.

This gives you the fast, reliable connection you need for critical operations such as:

Aplicaciones en la nube
Video conferencing and VoIP
Remote collaboration and large file transfers
