Abstract :
We review the state-of-the-art of both 980-nm and 1480-nm lasers for erbium-doped fiber amplifier (EDFA) pumping. High coupled power >200 mW as well as high reliability operation can support a dense wavelength-division multiplexed network. We demonstrate high-power EDFA with multipumping length-stabilized pump modules.
