摘要：
Two new pump configurations for pumping Er3+-doped fibres in the 807 nm pump band are presented and examined. An extra gain of 3.3 dB is obtained by pumping from both ends instead of pumping just from the input end. The noise figure for the investigated configurations is shown to have a minimum with regard to signal input power at -17 dBm.
