Abstract :
The authors analyze the sensitivity degradation in direct-detection optical FDMA networks as a result of signal filtering (both optical and electrical), interchannel crosstalk, channel beats (or nonlinear crosstalk), and intersymbol interference. The model used is valid for arbitrary linear time-invariant optical filters and received pulse shapes. The analysis is applied to on-off keying (OOK) systems using single-cavity Fabry-Perot filters and multistage Mach-Zehnder filters
