Q: What does it mean when a fiber modem is advertised as having "13 db optical budgets"? A: The optical budget, also known as maximum attenuation, includes the fiber connector loss of signal amplitude ...

An all-optical fiber-optic switching device that maintains the signal as light from input to output. Traditional switches that connect optical fiber lines are electro-optic. They convert photons from ...

A device that boosts light signals in an optical fiber network. Unlike regenerators, which have to convert light to electricity in order to amplify it and then convert it back again to light, the ...

Optical clocks have evaluated the latest 'one second' tick of the International Atomic Time (TAI) and provided these data for adjusting the tick rate of TAI. Optical clocks of the National Institute ...
