Many electricians have broadened their work model in recent years to include coaxial and Ethernet wiring for communications and data networks. This is usually seen as a good move, given the fact that ...
In this EC&M Tech Talk, Randy Barnett reviews the concepts, cables used, and NEC rules for Optical Fiber Cables (Art. 770). With the widespread use of fiber and expansion into residential markets, ...
There are enough seismometers around these days to detect and locate nearly all earthquakes on land, except the most minuscule ones. The seafloor is another story. It’s expensive and difficult to ...
It was once the most high-tech and futuristic feature you could find: Transmit sound -- with light! Lasers! A cable not of copper, but glass! Except, it was almost never glass, and was usually ...
Tiny circuits can go the distance. Researchers have mapped a noise-reducing magneto-optical response that occurs in fiber-optic communications, opening the door for new materials technologies. Optical ...
When it comes to earthquakes, the earlier the warning, the better. While current seismometers can pick up minor tremors with precision, they're relatively short-ranged and expensive, but now, a ...
