Abstract :
Summary form only given. In this paper we show that with a directly modulated transmitter in a CATV transport and distribution system with cascaded Er-doped fiber amplifiers (EDFAs) similar power budgets and transmission distances can be achieved as in an externally modulated system, without electronic predistortion, by using dispersion compensating fiber (DCF) and carefully designed EDFAs with low gain-slope.
