Abstract

Optical fibers are well established in the field of data communication and local area networks. It is obvious, that a high number of different measurement technologies and devices for optical fiber have been developed and produced over the last years. Examples are spectrometers, reflectometers and dispersion measurement setups. The fibers typically used in these areas are made from silica glass having core diameters between 10 μm (single mode) and 62.5 μm (graded index multi mode). Operation wavelengths are around 850 nm, 1,300 nm and 1,550 nm. Of cause, all the measurement devices are optimized for these conditions.
