报道了一种253 cm长的镧共掺Bi/sub 2/O/sub 3/-基掺铒光纤，在1554 ~ 1612 nm的58 nm扩展波长范围内，对142个密集波分复用信道同时提供大于20 dB的增益和小于6.7dB的噪声系数。在350 mW的1480 nm光泵浦下，掺铒光纤放大器的3 dB带宽（增益17-20 dB）为54 nm。光纤的功率转换效率约为54%。
The demonstration of a 253-cm-long lanthanum-codoped Bi/sub 2/O/sub 3/-based erbium-doped fiber which provides gain of greater than 20 dB and noise figure less than 6.7 dB to 142 dense wavelength-division-multiplexing channels simultaneously over an extended wavelength range of 58 nm from 1554 to 1612 nm is reported. The 3-dB (gain of 17-20 dB) bandwidth of the erbium-doped fiber amplifier is 54 nm when it is pumped with 350 mW of 1480-nm light. The power conversion efficiency of the fiber is about 54%.
