Because of these benefits of electrical transmission, optical communication is not common in short box-to-box, backplane, or chip-to-chip applications; however, optical systems on those scales have been demonstrated in the laboratory. Not electromagnetically radiating, and difficult to tap without disrupting the signalimportant in high-security environments. Other standards specify performance criteria for fiber, transmitters, and receivers to be used together in conforming systems. Fiber attenuation, which necessitates the use of amplification systems, is caused by a combination of material absorption, Rayleigh scattering, Mie scattering, and connection losses. or, by Rainer Klose, Swiss Federal Laboratories for Materials Science and Technology. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. More recently indirect viewing aids are used, which can comprise a camera mounted within a handheld device, which has an opening for the connectorized fiber and a USB output for connection to a display device such as a laptop. Typical modern multimode graded-index fibers have 3dB per kilometre of attenuation (signal loss) at a wavelength of 850nm, and 1dB/km at 1300nm.
