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 experimenting […]

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 to […]

This research breakthrough could lead to more accurate fiber optic gyros compared to mechanical units. WHAT OPTICAL […]

These systems offer capacity up to ~10 Tb/s on a single core fiber using a C-band Erbium doped fiber amplifier (EDFA). However, there are distinct challenges involved in developing and deploying high-capacity transoceanic distance transmissions […]
