What is Dark Fiber 2019 : What is Dark Fiber? Pros and Cons of Dormant Dark Fiber

There are several ways to set up a dark fiber network. Point-to-point or point-to-multipoint configurations are the most common ways to install and set up these networks. Dense Wavelength Division Multiplexing (DWDM), has been a huge factor in the development and improvement of Dark Fiber. DWDM occurs when many different data signals are transmitted at the same time, through the same optical fiber. Data signals are transmitted at the same time, but in order to keep the data signals separate, they are all transmitted at unique and separate wavelengths. A dense wavelength is a good way to increase bandwidth and to allow additional data to be sent via fiber optics. Additionally, the single optical cable can then be turned into multiple virtual fibers. This kind of technology results in high-quality levels of internet performance, a powerful and secure network, and lightning-fast internet speeds.
