All the optical fiberOptical fiber A cable made of glass fiber through which a light signal is transmitted over long distances for broadband network access. Compared to copper cables, optical fiber can transmit signals much faster, up to 40 Gigabits per second. It is therefore ideal for quickly transferring large amounts of data; it is also unaffected by external interference (electromagnetic interference, temperature variations, etc.). While fiber optics certainly offers the advantage of fast, high-quality and secure data transmission, its high installation cost is a drawback for network builders. Read the news to find out more: “Optical fiber, what it is and how it works”. that is laid, but not yet illuminated by data transmission equipment. Operators always install more cables than they intend to use at the time of installation to anticipate future demand for this type of networkNetwork In computer language, the term network defines a set of hardware and software devices which, when linked together, enable the exchange and sharing of resources, data or information. In a computer network, the devices that generate, route and terminate data are called network nodes.. This is primarily possible because the cost of fiber optics is a fraction of the total cost of building infrastructure (excavation, work sites, etc.). Dark fiberDark fiber All the optical fiber that is laid, but not yet illuminated by data transmission equipment. Operators always install more cables than they intend to use at the time of installation to anticipate future demand for this type of network. This is primarily possible because the cost of fiber optics is a fraction of the total cost of building infrastructure (excavation, work sites, etc.). Dark fiber can then be rented and bought by entities that then connect their own transmission equipment to it. can then be rented and bought by entities that then connect their own transmission equipment to it.
