Fiber optics, or optical fiber, refers to the medium and the technology associated with the transmission of information as light pulses along a glass or plastic strand or fiber. Fiber optics is used long-distance and high-performance data networking. Fiber optic cables are used since they hold a number of advantages over copper cables, such as […]

Vibrations from loud events like lightning pass from the air to the Earth’s surface. Underground fiber optic telecommunications, which carry internet and phone service, can pick up the rumble of thunder underground, an advance that can offer scientists a new way to detect environmental hazards, and image deep inside the Earth. The study, published in

Eskom, which is going to cost the government R150bn over the next decade, is cited as the single-biggest threat to SA’s fortunes. However, with some creativity the power utility could take fast internet to the masses. It is sitting on a fibre gold mine. While the public has every right to be angry and demand

Light has travelled through a wood-based optical fibre, offering the possibility of biodegradable Internet of Things (IoT) sensors or simple moisture monitors. Researchers at VTT made the new fibre, which has a core of wood cellulose modified with ionic solvents developed at the Finnish research centre. The core has a cladding of cellulose acetate. Light
