The dark fiber is an idle optical fiber that is used in network and telecom communications. It is also known as unlit fiber or black fiber. It is called dark because no light pulsation is being transmitted through it. There are number of ways to assemble a dark fiber network. The point-to-point or point-to-multipoint configurations are the mainly general ways to set-up whereas dense wavelength division multiplexing (DWDM) is a significant factor in the development and improvement of dark fiber. The dark fiber network provides scalability, enhanced security, compact network latency, and consistency. There are mainly two types of dark fibres which are; single mode fiber and multimode fiber. These fibers are predominately used in telecommunication, IT and ITES. Moreover, Dark Fiber Networks also find extensive applications in the automotive, healthcare, and aerospace sector banking, insurance, financial services industries, healthcare and restaurants world that never stops. Dark fibre networks are point to point and self-healing ring. Because both ends of the link are controlled by the similar association, dark fibre networks can operate using the latest optical protocols using wavelength division multiplexing to add capacity where needed, and to offer an upgrade path between technologies. First dark fibre was installed in the U.S. during the telecom boom of the late 1990s and early 2000s.
