erbiumSoft, lustrous, greyish, metallic element of the lanthanide series, atomic number 68, relative atomic mass 167.26. It occurs with the element yttrium or as a minute part of various minerals. It was discovered in 1843 by Carl Mosander (1797-1858), and named after the town of Ytterby, Sweden, near which the lanthanides (rare-earth elements) were first found. Erbium has been used since 1987 to amplify data pulses in optical fibres, enabling faster transmission. Erbium ions in the fibreglass, charged with infrared light, emit energy by amplifying the data pulse as it moves along the fibre. |

| NYSE:LU), has a proven track record of being first in the industry with application specific fibers, optical connectors, ribbon cables, erbium doped fibers, Raman fiber lasers and more. Frechet and his colleagues are placing rare-earth elements such as erbium inside dendrimers for use in the telecommunications industry In fiber-optic cables, light loses some of its intensity as it travels along, so telephone companies install amplifiers every mile or so to boost the signal. With expertise in submarine system design, optical transmission, Raman amplifiers, erbium amplifiers, transmission equipment design, manufacturing systems, and analysis of optical transmission, Kidorf Innovative Methods has been serving both military and civilian clients in the field of optical transmission. |
