Hezbollah has begun using fiber-optic FPV drones—tethered, high-bandwidth drones—an approach linked to the Ukraine conflict, with AP photos showing a drone with cables in Israel after crossing from Lebanon and Ukrainian-made fiber-optic FPV drones documented in the Kyiv region.
Australian physicist Enbang Li has built a compact, three‑foot device that uses gravity to bend light via spiraled fiber-optic coils, detecting tiny picosecond time delays to sense gravitational changes. The approach could enable high‑precision gravity sensing for mapping underground features, monitoring magma, and improving sensing on moving platforms like planes and submarines. While still in early lab stages, the work suggests photons can interact with Earth’s gravitational field in new ways and may prompt fresh thinking about light’s behavior, with findings published in Scientific Reports.
Hezbollah is ramping up FPV drone strikes on IDF armor and personnel in Lebanon, including reports of fiber-optic guided attacks on Merkava tanks and other vehicles; Israel counters with Trophy APS, but the true damage remains unclear, signaling a broader spread of FPV drone warfare in the region.
Ukraine’s Kharkiv region reports a Russian FPV drone reached the city via a fiber‑optic cable for the first time since the full‑scale invasion. The drone hit a tree in the Kyivskyi district around 3 p.m. on Feb. 25; no casualties were reported, and the Kharkiv regional prosecutor’s office opened a pre‑trial investigation. Fiber‑optic FPV drones extend range and can evade electronic warfare, with countermeasures mainly limited to physical destruction or obstruction; Kharkiv’s proximity to Russian‑occupied areas makes this development notable in the evolving drone warfare.
Orland Park, Illinois, has suspended all fiber-optic construction permits due to numerous complaints about property damage, unaddressed issues, and safety concerns, including a recent power outage caused by contractor errors, prompting the village to enforce stricter regulations on internet service providers.
Unjammable fiber-optic drones are increasingly used in Ukraine and Russia, leaving cables across the battlefield that pose navigation and safety challenges for soldiers, who must move cautiously to avoid entanglement and traps.
Amphenol's $10.5 billion acquisition of CommScope's CCS unit caused CommScope's stock to soar 75%, boosting Amphenol's presence in the AI and data center interconnect markets, with expected first-year sales of $3.6 billion and a 26% EBITDA margin.
Japan's National Institute of Information and Communications Technology and Sumitomo Electric set a new internet speed record of 1.02 petabits per second using advanced fiber optic technology, enabling incredibly fast data transfer, though this speed is currently only achievable in a lab environment and not available to the public.
Researchers at the University of Rochester and RIT have developed the Rochester Quantum Network (RoQNET), an 11-mile-long quantum communication system using photons transmitted over fiber-optic cables, which could enhance secure communications and enable new quantum technologies. The system leverages integrated photonic chips and aims to connect various research facilities, advancing scalable and cost-effective quantum networking.
Researchers at UK's Aston University have achieved a data transfer rate of 301 terabits per second using a single fiber optic cable, which is 1.2 million times faster than the average American broadband connection. By accessing new wavelength bands normally unreachable in existing optical fibers, the team utilized an optical processor to access the never-before-used E- and S-bands, achieving these speeds without the need for new, high-tech fiber optic lines. This breakthrough could potentially allow internet providers to significantly increase standard speeds without overhauling current fiber optic infrastructures.
