Using Dark Fiber Optic Cables to Detect Earthquakes

Leave a Comment

Researchers hope to use networks of unused, dark fiber optic cables to help detect underground sound waves that can warn of an impending earthquake.   Millions of miles of unused, dark fiber optic cables are installed underground. A research team of scientists from the University of California (Berkeley) and Lawrence Berkeley National Lab have been […]

Celebrating Women and Girls in Science

Leave a Comment

Today the United Nations, its partners and women and girls around the world are marking the International Day of Women and Girls in Science.   Recent studies suggest that 65 per cent of children entering primary school today will have jobs that do not yet exist. While more girls are attending school than ever before, […]

New Ways to Twist and Shift Light

2 Comments

The National Physical Laboratory (NPL) recently conducted photonics research that may lead to new quantum technologies and telecom systems. The researchers discovered unexpected qualities in light that could, in the long term, lead to completely new electronic devices and applications.   Light is frequently used in electronics involved in telecommunications and computing. One good example […]

Lighting Up Dark Fiber

Leave a Comment

Last month, internet speeds in Jackson, Mississippi, jumped from 1 Gb to 100 Gb. This leap forward is part of the city’s work to light up “dark fiber” in the robust fiber optic network that it owns. The Origin of Dark Fiber The term “dark fiber” refers to unused or underused fiber optic infrastructure (optical fibers, […]

Fiber to the Home Growth Keeps Exploding

Leave a Comment

The growth in Fiber to the Home (FTTH) just keeps exploding. In fact, for the first time ever, optical fiber passed DSL in home usage during 2018. Fiber is now the second most-frequent connection for North American home Internet.   And FTTH is also the second most-often-used, fixed broadband connection medium in North America. A […]

The “Wet Net” World of Underwater Fiber Optic Cables

Leave a Comment

You panic when even a few drops of water fall on your laptop. Everyone knows that water and electronics don’t “mix.” That’s why it seems so ironic that most of the Internet’s “hard” infrastructure lies underwater on the ocean floor.   Virtually all global data travels through millions of miles of submarine fiber optic cables beneath […]

5G: What’s All the Hoopla About?

Leave a Comment

There’s been lots of excitement and even some “hype” around the idea of 5G. But what is it really? Does it mean just faster internet? Will it really be that much better than 4G? Many people are asking these questions as the FCC begins to auction the first licenses for the airwaves that will carry […]

Can a Quantum Network “Hacker Proof” Fiber Optic Cables?

Leave a Comment

In 2013, Edward Snowden, a U.S. National Security Agency contractor, leaked documents showing that intelligence agencies were spying on the data of private citizens. One disturbing fact was that the spies tapped into optical fiber cables to access the huge amount of data moving through these cables.   Snowden’s disclosures pushed researchers to use quantum science […]

Smaller Endoscopes from New, Air-Filled Optical Fiber Bundles?

Leave a Comment

A new, air-filled optical fiber bundle could dramatically improve medical endoscopes. This technology could also help create endoscopes that produce images using infrared wavelengths. If so, this breakthrough would allow diagnostic procedures that aren’t currently possible.   In the Optical Society (OSA) journal Optics Letters, University of Bath (U.K.) researchers showed that these new fiber […]

Could “Twisted” Fiber Optics Create a 100 Times Faster Internet?

2 Comments

Researchers at Australia’s RMIT University recently discovered a new fiber optic breakthrough that could lead to 100 times faster internet speeds. This new development detects light that has been twisted into a spiral.   According to research in Nature Communications, developers could upgrade existing fiber optic networks and boost efficiency using this discovery.   HOW […]
