Abstract :
We present a detailed study of the dc optical prefiltering (OP) technique in subcarrier multiplexed (SCM) lightwave systems. A numerical model, including all of the most relevant limiting effects, is used in combination with Prony´s method in order to obtain an accurate assessment of analog transmission systems performance. Intrinsic limitations of the dc-OP technique are highlighted and the full numerical results are compared with those obtained from limited analytical approximations.
