Dark Fiber

Dark fiber, also known as unlit fiber, is a type of optical fiber cable that has been installed without active transmitter and receiver equipment. It is used to provide extra capacity to existing networks and is often leased out to other companies that have the necessary equipment to transmit signals through it.

Dark fiber consists of a pair of optical fibers, usually encased in a protective jacket. Each fiber contains an inner core that is made of glass, allowing light to travel through it. The jacket also contains Kevlar cables and other materials designed to protect the fiber and make it more durable.

The dark fiber is installed in conduits that are buried or suspended from poles or buildings. The conduits contain various types of fiber cables, including dark fiber. These conduits can be used for both long-distance and local networks, depending on their length and the type of fiber cables that are used.

Dark fiber has several advantages over other types of fiber cables. It is more reliable, as the cables are not affected by weather or other environmental conditions. It is also more secure, as it is not exposed to electromagnetic interference. Furthermore, dark fiber is easy to install and can be used to create a high-speed and reliable connection.

The dark fiber market is growing rapidly, as more companies and individuals are beginning to recognize its advantages. It is also a cost-effective solution for providing fast and reliable internet access. Additionally, dark fiber can be used to connect multiple buildings or locations, which can help improve network speeds and reduce costs.
