What is Fiber Internet?

Fiber-optic internet is the fastest broadband connection which delivers speeds as fast as 940 Mbps, with ultra-low lag.

The technology makes use of fiber optic cables that allow data transfer to occur at 70% of the speed of light. Plus fiber optic cables are not as vulnerable to extreme weather conditions, and resist electrical interference effectively. It is ideal for homes where many users connect at once.

How Does Fiber-Optic Internet Work?

Fiber-optic technology is more complex than its predecessors.

Transmission of data occurs in the form of light pulses, and not electricity. Optical fibers, thinner than human hair, carry these pulses down the line. Once at their destination, these light pulses are converted into electrical output via the optical network terminal. And, from here via an Ethernet connection the signal reaches your device.

What Are the Advantages of Fiber Internet?

  • High bandwidth, ultra-fast speeds, and more reliability than any other internet connection type―DSL or Cable
  • Best for households where multiple users connect simultaneously for bandwidth-extensive activities such as video streaming, competitive online gaming, Cloud backup etc.
  • Ideal for a seamless smart home experience―reliably connects your smart home appliances and security devices
