We investigate 40-Gb/s cost-efficient transmitter for access and metro networks. This comprises a standard directly modulated distributed-feedback (DFB) laser subsequent optical filter. Large dispersion tolerance of this is realized by chirp control through the phase correlation between adjacent bits destructive interference in order to erase power ldquo0rdquo while enhancing extinction ratio. The model DFB optimum parameters filter have been numerically analyzed. chirp-managed 42.8-Gb/s transmission over 20-km single mode fiber (SSMF or SMF-28) without compensation centralized lightwave WDM-PON system are experimentally demonstrated. also 100-m graded index plastic (GI-POF). Moreover, application network 240-km SSMF SMF-28 has investigated paper.
