erbium-doped fiber amplifier

[¦ər·bē·əm ‚dōpt ‚fī·bər ′am·plə‚fī·ər]
(communication)
An optical-fiber amplifier whose fiber core is lightly doped with trivalent erbium ions which absorb light at pump wavelengths of 0.98 and 1.48 micrometers and emit it at a signal wavelength around 1.5 micrometers through stimulated emission. Abbreviated EDFA.
