Abstract :
In this paper, the authors present a double-pass triple-band doped fiber amplifier including an embedded dispersion-compensating fiber. The amplifier employs only silica-based erbium-doped fibers to achieve signal amplification over S-, C-, and L-bands. Experimental characterization is carried out in terms gain and noise figure over the coarse-wavelength-division-multiplexing (CWDM) wavelength grid. By providing optical gain to seven CWDM channels spectrally located between 1490 and 1610 nm, the amplifier can extend the reach of a CWDM optical bus well beyond the 100-km limit
