Researchers have shown how ultrastable optical signals from optical clocks can be transmitted across tens of kilometers of deployed multicore fiber carrying telecommunications data. Nazanin Hoghooghi, ...

A Microsoft-backed research team from Lumenisity (a spinout of the University of Southampton Optoelectronics Research Center) has built a hollow-core cable with what it claims is the lowest signal ...

Technicians launch an aerostat containing a High Antennas for Radio Communications, or HARC, payload. An optical fiber tether carries an analog ground radio signal to its corresponding antenna aboard ...

Fiber optic cables are very fast—achieving data speeds of up to a couple hundred terabits per second. However, AI data centers today demand more bandwidth still. This insatiable appetite has spurred a ...

Despite the modern world relying heavily on digital optical communication, there has not been a significant improvement in the minimum attenuation—a measure of the loss of optical power per kilometer ...

Fiber-optic services are becoming more popular, and networks are expanding to cover more areas for faster data transfer speeds. Fiber-optic data transfer differs from traditional methods like ...

In Sept, 2025, Microsoft Azure announced it is scaling its hollow core fiber (HCF) production by outsourcing manufacturing to ...

Once a month or so, I have the privilege of sitting down with Editor-in-Chief Elliot Williams to record the Hackaday Podcast. It’s a lot of fun spending a couple of hours geeking out together, and we ...
