Four Basic Elements in a WDM System

We know that fiber can carry more data over long distances than any other physical medium. That makes fiber a very precious material. And how to make the most use of your fiber plant becomes a question. So there comes Wavelength Division Multiplexing (WDM). Why Should We Deploy WDM? WDM can multiply your fiber capacity by creating virtual fibers. The…

Decoding the Wavelength in Fiber Optics

The wavelength, as we have been heard so many times in fiber optics, is not simply the term used to refine the color of the light. The light used in fiber optics is not the one that we can see by our eyes, as we use light in the infrared region which has wavelengths longer than visible light, typically around 850nm, 1300nm, 1550nm

Researchers Discover New Form of Light for Secure Optical Communication

Future Optical communications might be more secure thanks to Professor John Donegan and team for their research conducted at the Trinity College in Dublin, Ireland. The research team found a new property of light while passing it through crystals. Usually, when light hits our eyes, the spinning photons twist infinitesimally. In Quantum physics, the force of the twist/spin called the angular momentum has been thought to be a direct multiple of a constant called Planck’s constant. However, John Donegan and team discovered a new form of light with an angular momentum that is exactly half of the conventional one. The team believes the new discovery would have practical applications in secure optical communication.
