What is dark fiber used for?

General

Dark fiber is a fundamental resource in the world of telecommunications and data networks, but what exactly is it and what benefits does it provide? Why are more and more companies and operators considering it a strategic option to boost connectivity and digital growth?

What is Dark Fiber?

Fiber optics is a set of cables composed of very fine strands of glass or plastic, designed to transmit information through pulses of light. In this context, the term “dark fiber” is used to refer to those fiber optic cables that, despite being installed and available, are not being actively used to transmit data. In other words, they are “dark” because they have not yet been lit with digital signals.

These cables are usually part of infrastructures deployed in advance, and their potential lies in the fact that they can be “turned on” or “lit” when needed, thus allowing data transmission at high speeds. Dark fiber is contrasted with “lit fiber,” which is already operational and dedicated to the transmission of information.
