What is terbium doped fiber amplifier??? HamidAliKhan 31-December-2008 11:08:11 AMComments Its basically device which is basically an optical or IR repeater that amplifies a modulated laser beam directly. Posted by HamidAliKhan A device which is basically an optical or IR repeater that amplifies a modulated laser beam directly. Posted by sagitraz An erbium amplifier, also called optical amplifier or an erbium-doped fiber amplifier or EDFA, is an optical or IR repeater that amplifies a modulated laser beam directly, without opto-electronic and electro-optical conversion. The device uses a short length of optical fiber doped with the rare-earth element erbium. When the signal-carrying laser beams pass through this fiber, external energy is applied, usually at IR wavelengths. This so-called pumping excites the atoms in the erbium-doped section of optical fiber, increasing the intensity of the laser beams passing through. The beams emerging from the EDFA retain all of their original modulation characteristics, but are brighter than the input beams. Posted by robina A typical setup of a simple erbium-doped fiber amplifier (EDFA) is shown in Figure 1. Its core is the erbium-doped optical fiber, ... visit it www.rp-photonics.com/erbium_doped_fiber_amplifiers.html - 29k - Posted by waqasahmad An erbium amplifier, also called optical amplifier or an erbium-doped fiber amplifier or EDFA, is an optical or IR repeater that amplifies a modulated laser beam directly, without opto-electronic and electro-optical conversion.
