Experimental and numerical investigations are realized to show the impact of the number of ASE-filters on the S-band gain of an erbium doped fiber. Gain as a function of (number of filters, filter ASE-isolation) is studied to optimize the S-band amplifier by using ASE-isolation tunable all-fiber fil
In this paper, a novel configuration of reflection L-band erbium-doped fiber amplifier (L-EDFA) via inserting a 980 nm pump laser diode (LD) in the input part was constructed. By selecting appropriate power ratio of the 980 and 1480 nm pump LD, gain and noise figure (NF) of the L-EDFA are greatly im
A new configuration of L-band erbium-doped fiber amplifiers (EDFAs) is presented here. The system contains a double-pass L-band EDFA and an optical preamplifier. Different from conventional preamplified double-pass L-band EDFA systems in which only the forward ASE of the preamplifier is re-used as a
