Andreas Fichtner strips a cable of its protective sheath, exposing a glass core thinner than a hair — a fragile, 4-kilometer-long fiber that’s about to be fused to another. It’s a fiddly task better ...

- Development of the world's first practical surface-emitting laser suitable for optical fiber communications systems. - Utilization of quantum dots as an optical gain medium, enabled by NICT's ...

Pipeline contents are typically valuable, volatile, and harmful to the environment if allowed to escape. With them being susceptible to aging, accidental damage, or tampering, the chances of an escape ...

A high-capacity fiber-optic communication cable unspools as the drone flies; with no tension, there is no risk of tangling of breaking. German developers are demonstrating a new drone in Ukraine ...

China Mobile has taken a significant leap forward in optical network technology with the successful launch of the first 800G hollow-core fiber transmission test network. Conducted in Shenzhen-Dongguan ...

Through an emerging technology called distributed fiber optic sensing, cables bringing high-speed internet to American households can be used to detect temperature changes, vibrations, and even sound.
