EYDFA-C-HP-BA-33-SM-B2 High Power Erbium-doped SM Fiber Amplifier
Erbium-doped fiber amplifiers (EDFAs) are optical signal amplification devices based on erbium-doped fiber, operating in the wavelength range of 1530–1565 nm, which coincides with the minimum loss window of optical fiber communication. Their core functionality involves exciting erbium ions (Er³⁺) using a 980 nm or 1480 nm pump light source, achieving all-optical amplification of the optical signal without photoelectric conversion. Since its introduction in 1985, the EDFA has become a core component of optical fiber communication. In 2022, institutions such as the China Information and Communication Technologies Group (CICT) further promoted its independent development, integrating the RS232 communication protocol for intelligent monitoring.
