co-doped silica fiber cascaded is given in order to get more power gain while not interfering with the characteristic of its ultra-wide band amplification.Based on the rate and power equations
the operational characteristics of two cascaded Er

co-doped silica fibers are simulated.The simulation results show that the power gain of two fibers cascaded is up to 20 dB.The new method basically solves the problem of its ultra-wideband amplification while having low power gain.Compared with other wideband fiber amplifiers at present
it can be concluded that this kind of two Er
