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

OSAKA, Japan--(BUSINESS WIRE)--Sumitomo Electric Industries, Ltd. (TOKYO:5802)(ISIN:JP3407400005) has developed a new-type coupled multi-core optical fiber suitable for ultra-long-haul transmission, ...

In a world where milliseconds matter and data volumes are exploding, the networks that connect our digital lives are quietly approaching a breaking point. Every time we stream a movie, query an AI ...

Microsoft-backed researchers have unveiled a new design for hollow-core fiber that promises record-low signal loss and faster transmission speeds. Unlike conventional solid-core optical fibers, which ...

DARPA has succeeded in creating hollow-core photonic-bandgap optical fiber, which allows light to travel along its length at around 99.7% the speed of light, or a 30% improvement over conventional ...

The Azure team’s breakthrough, tested over 1,200 km of fiber, cuts transmission loss to below 0.1 dB/km and expands bandwidth, promising faster, cheaper, and more energy-efficient data networks.

A team of Microsoft-backed researchers has unveiled a new type of hollow core optical fiber that promises unprecedented speed and lower latency for the internet. This breakthrough was published this ...

Data travels across the cloud mainly as light via optical fibers made from solid glass. But that light—and thus that data—travels faster through air. “With hollow core fiber, the glass [has] an air ...

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 ...

Recently, a research group led by Prof. JIANG Haihe from Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS) designed a 6-hole micro-structure anti-resonant air-core ...
