Wavelength Division Multiplexing (WDM) is a technology found in fiber optic communications. WDM uses a single fiber to transmit multiple optical signals. It does this by breaking up the signal into different frequencies or wavelengths of color. The various wavelengths indicate that different amounts of data are being transmitted simultaneously. This results in an increase in capacity and allows bidirectional communication over any single fiber. That is to say, the fiber can have a signal going in one direction and another going in the opposite direction. How WDM Works For Read More

Elasticity and conductivity are often mutually exclusive in industrial materials, making it difficult to find a material that one could twist and bend and use for electric conduction at the same time. Electrical wires, often made out of copper or some other metal stretched out into threadlike widths, were invented to try and bridge the gap but was impractical if one wished to apply them to a surface. Metals are also highly reactive to chemicals and this is a problem if one wanted to use them for everyday purposes. As Read More

DVI (Digital Visual Interface) is a video connector designed by the Digital Display Working Group (DDWG), aimed at maximizing the picture quality of digital display devices such as digital projectors and LCD screens.

Older Video Technologies Previous standards such as Video Graphics Array (VGA) were designed exclusively for CRT-based devices and hence did not Read More

Nanopollution refers to the waste matter or byproducts of nanoscopic device or material manufacture. Nanoscopic device or material manufacturing processes leave behind nanoparticles (smaller than a billionth of a meter) which can infiltrate the cells of humans, animals and all living organisms that may be unprepared for the influx of artificial particles. A 1941 study from Johns Hopkins Hospital discovered that nanoscopic particles, when inhaled, could make their way into the brain via the olfactory tract. This raises some concerns about the possible health risks connected to the recent developments Read More
