EDFA Amplifiers (OPA, OBA) 1528–1565 nm

SKU: RMEA

EDFA is an erbium-doped fiber amplifier. It is used to amplify the optical power up to 48 channels (channel interval of 100 GHz) or 96 channels (channel interval of 50 GHz) at the C band at the same time in the transmission link. It has characteristics of flat gain, stable output, low noise figure, etc. It is mostly used in DWDM high-speed and long-haul transmission.
These Erbium-Doped Fiber Amplifiers (EDFAs) are engineered for a long operational lifespan, typically designed to function reliably for over 10 years. This durability is achieved through high-quality components and robust manufacturing processes. The design considerations include thermal management, component selection, and rigorous testing to maximize the amplifier’s longevity and efficiency.
For narrow-linewidth CW seeds below several MHz, the maximum output power is limited by stimulated Brillouin scattering (SBS). As an example, for linewidths around 500 kHz, SBS limits output powers above a few watts.
