12-core cable; 96 fibers Sumitomo also announced that it has fabricated a 12-core MCF cable using the new 8-fiber MCFs, meaning that 96 cores are included within an outer diameter of 3mm. here, the ...

OSAKA, Japan--(BUSINESS WIRE)--Sumitomo Electric Industries, Ltd. (TOKYO:5802)(ISIN:JP3407400005) has developed a multi-core optical fiber including 8 cores in the standard 125-µm cladding ...

A new type of optical fiber filled with nothing but thin air has been found to be particularly effective for carrying out quantum key distribution (QKD), a security protocol that is in principle ...

Called hollow core fiber, the technology enables data to travel 50% faster than in the optical cables that are typically deployed for 5G networks, according to Lumenisity, a spin-out company from ...

In 2018, Marra’s team demonstrated that they could detect quakes with undersea and underground fiber-optic cables up to 535 kilometers long, far exceeding DAS’s limit of about 100 kilometers.

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 ...
