Do you know how to save fibers in your network to achieve economical cabling? Here may have the answer you want to know.
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
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.
Driven by growing Internet-based operations and the increasing delivery demands for time-sensitive applications, there appeared a boom in the deployment of 10/100M Ethernet or Fast Ethernet due to the low cost and compatibility with existing local area networks (LANs) over the past few years. Thanks to the advances in Ethernet technology, the Gigabit Ethernet, 1GbE, (1000M Ethernet) has been deployed as the later development of the Ethernet standard beyond the 100Base-T version. And this 1GbE has proven itself as an ideal solution for the increased bandwidth requirements of growing networks in data centers with the time passing by.
