The Nuphoton Technologies NP2000 is an Erbium Doped Fiber Amplifier (EDFA) series delivering high-performance optical amplification across 915 nm to 1550 nm. Available as standalone gain blocks, microprocessor-controlled modules with RS232 interfaces, or rack-mount units, the NP2000 provides stable optical power for telecommunications, research, and industrial applications. The NP2000ASE variant functions as a broadband Erbium Doped Fiber Light Source (ASE), offering tunable output across C-band, L-band, or combined C&L spectrum.
