EDFA amplifiers
EDFA amplifiers are a cost effective choice for light amplification on DWDM projects in which fiber spans are too long to be achieved strictly with conventional optical transceivers. EDFA light amplifiers are used in DWDM telecom and CATV applications. The Erbium Doped Fiber Amplifiers act at the optical light level without performing any conversion to electrical signals. EDFA units amplify the whole C-band of 45 channels from the ITU 100GHz grid within a single device, thus signficantly decreasing costs related to expensive O-E-O (Optical-Electrical-Optical) regeneration points.
