Effects of cascading optical filters are investigated for a phase modulated coherent optical OFDM system based
on Hartley transform. The evaluation is performed by means of numeric simulations in a 10 Gb/s system with
a total bandwidth of 10 GHz. First a back-to-back (no fiber) case is assessed. Results show a 3 dB power penalty
after a single filter of only 68% of the signal bandwidth. The same penalty is achieved when cascading 10 filters
of 21.6 GHz bandwidth. Additionally, the penalties associated to the introduction of fiber spans between filters
are investigated.Peer ReviewedPostprint (published version)
