Abstract :
Analytic estimates of pulse broadening and system penalty caused by wavelength-division-multiplexing (WDM) filter amplitude variation is derived. We show that root mean square pulsewidth is not a reliable measure of system penalty and noise equivalent bandwidth plays a key role in determining system penalty.
