摘要：
The influence of amplified spontaneous emission (ASE) on the performance of erbium doped fibre amplifiers (EDFAs) has been studied through the use of an ASE indicator, the nearly-no-ASE factor (NNAF). A simple and useful formula is also presented for the analysis of errors resulting from neglecting the ASE.
