single mode fiber

Contributor(s): Mario Grullon Damian

In optical fiber technology, single mode fiber is optical fiber that is designed for the transmission of a single ray or mode of light as a carrier and is used for long-distance signal transmission. For short distances, multimode fiber is used.

Learn about fiber optic cable types and why smaller is better Learn about fiber optic cable types, how the most widely used one -- 62.5/125-micron loose tube -- is constructed, and why smaller is better when it comes to fiber optics.

Gbps (billions of bits per second) Gbps stands for billions of bits per second and is a measure of bandwidth on a digital data transmission medium such as optical fiber.

fiber to the x (FTTx) Fiber to the x (FTTx) is a collective term for various optical fiber delivery topologies that are categorized according to where the fiber terminates

The physics of fiber in optical networks 'Optical Fibers,' Chapter 5, from "The Cable and Telecommunications Handbook, Volume 2, Third Edition" focuses attention on the history and evolution of optical fiber, as well as special fibers that are currently in use in optical networks. Additional topics covered are the mathematical equations used to build optical networks, the need for more efficient multiplexing schemes and flexible control methods, and the development of standards initiatives. This chapter provides readers with a thorough understanding of the components to create and use optical fibers effectively.
