Air-filled Fiber Cables capable of Outperforming standard Optical fibers

Air-filled fiber cables capable of outperforming standard optical fibers
“Hollow core optical fibres with comparable attenuation to silica fibres between 600 and 1100 nm” has been published in Nature Communications with DOI 10.1038/s41467-020-199107

The next generation of optical fiber could be a step closer as a new study has shown that fibers with a hollowed out center, created in Southampton, could reduce loss of power currently experienced in standard glass fibers.

The COVID-19 crisis has seen people all over the world rapidly move their work and social lives online and communities have never relied on the internet more. The ever-increasing number of Zoom calls and webinars has highlighted the need to keep advancing the technology that has made this possible.

For over 50 years, optical fibers made of silica glass have been the transmission med...

Terahertz Wireless Tech Could Bring Fiber-Optic Speeds out of a Fiber

Scientists have developed a terahertz (THz) transmitter capable of signal transmission at a per-channel data rate of >10 Gb/s over multiple channels at ~300 GHz. The aggregate multi-channel data rate exceeds 100 gigabits per second. The transmitter was implemented as a silicon CMOS integrated circuit, which would have a great advantage for commercialization and consumer use.

This technology could open a new frontier in wireless communication with data rates 10X higher than current technology allows. The THz band is a new, vast frequency resource not currently used for wireless communications. Its frequencies are even higher than those used by the mm-wave wireless local area network (57 GHz to 66 GHz), and bandwidths are much wider...
