Abstract
An optimized optical transmitter for use with a 1.3 .mu.m directly-modulated DFB laser. A negative fiber dispersion is intentionally introduced into the system by selecting the operating wavelength to be less than the nominal zero-dispersion value. The introduction of the negative fiber dispersion reduces the system power penalty and results in an optical transmission system useful over relatively short lengths of standard single mode fiber (50 km, for example) without the need for additional amplification.
