We successfully demonstrated the 1.25 Gb/s operation of ASE injected RSOA with 50 GHz channel spacing by using the injection current adjustment, the dispersion management and the receiver with decision threshold level control. We could mitigate the RIN degradation caused by post filtering through the injection current adjustments, and also alleviate the dispersion induced RIN degradation by means of the dispersion management to take advantage of the insertion of dispersion compensating fiber (DCF). Finally, the use of optical receiver with optimized decision threshold level could eliminate some sorts of error floor which are attributed to unequal noise distribution at mark level. © 2010 IEEE.
