EDFA Amplifiers C-Band: 1528-1565nm (< 26dBm), 1535-1565nm (< 41dBm)

EDFA (Erbium-Doped Fiber Amplifier) is a type of optical amplifier used in fiber-optic communication systems to boost signal strength over long distances. EDFA uses a silica fiber that is doped with erbium ions (Er³⁺) as the gain medium. EDFAs typically operate in the C-band (1530-1565 nm) and L-band (1565-1625 nm), which are the standard wavelength ranges used in most long-haul fiber-optic communication systems. However, when amplified optical power exceeds 26dBm, EDFA’s ability to amplify signals below 1540nm decreases. To amplify the full C-band at a higher optical power beyond 26dBm, Agiltron produces EYDFA, an advanced version incorporating ytterbium to achieve higher power output and efficiency.

EDFAs are usually pumped using laser diodes at wavelengths around 980 nm or 1480 nm. They are widely used in optical communication systems, including Wavelength Division Multiplexing (WDM) systems, because of their ability to amplify multiple wavelengths simultaneously. EDFAs are highly efficient for the wavelengths they are designed to amplify, particularly in the C-band. Agiltron uniquely offers EDFA with an extended operation temperature range of -25 to 70 oC.
