Abstract
Analytic models of directly and externally modulated fiber-optic links were derived and experimentally confirmed. The models were used to optimize the operating parameters of fiber-optic links. Experimental measurements on these optimized links indicated net incremental link power gains of +3 dB for direct modulation and +11 dB for external modulation. The implications of these optimizations for other measures of link performance, such as bandwidth and noise figure, are presented.<>
