Abstract :
We analyze fiber transmission penalties due to erbium-doped fiber amplifier (EDFA) power transients that result from fiber nonlinearity and ASE noise in a chain of 10-20 EDFAs with as many as 32 wavelength-division multiplexing (WDM) channels. We find due to worst case power transients: (i) system performance is severely degraded (up to few 10s of dB) both in single-mode fiber and dispersion-shifted fiber, (ii) the SNR can be reduced up to 8 dB in a 32-channel system, and (iii) a control channel to suppress power/SNR transients may impose an additional few dBs, which increases with the bit rate.
