Sumitomo Electric Industries has developed a multi-core optical fiber (MCF) including 8 cores within in the standard 125-μm cladding suitable for optical interconnects, and realized an ...

UK telecoms company BT is trialing the use of hollow core fiber cables in its 5G networks, with some promising results. Written by Daphne Leprince-Ringuet, Contributor June 1, 2021 at 1:25 a.m. PT ...

BT experimented with QKD over a six-kilometer-long cable of hollow core fiber, a technology that it has been working on for the past few months as an alternative to traditional fiber optic cables.

Fiber optic cables are commonly used for core network lines and connections that must span long distances, such as those used by Internet service providers. This is due to the fact that fiber ...

The achieved core density was more than 2 times higher than those of ever-reported fiber optic communication cables. We also evaluated the transmission characteristics in 1.3-μm band of the 1.1 ...

This creates something akin to a fiber-optic cable made of air: Instead of a transparent core covered in plastic cladding that guides light in conventional fiber optics, the dense air acts as the ...

With an average coupling transmission efficiency of 77.3% and a maximum of 85%, the fiber optic cable system demonstrates impressive performance.

As part of the study, researchers used a small section of the state’s fiber optic infrastructure and examined data from a 2021 earthquake to understand the possibilities of using fiber optic cables.

Thousands of miles of fiber-optic cables, already in place across California, can shake up the study of earthquakes. New research out of Caltech used a section of telecommunication fiber to sense ...

The cable, called hollow-core fiber, is a next-generation version of the fiber-optic cable used to deliver broadband internet to homes and businesses. Made of glass, such cables carry data encoded ...

The cable was cable strung on three 35-foot utility poles in Princeton, New Jersey between June 9 and June 24, 2021. [Related: .] The cable picked up the insects’ sounds.
