80 km transmission at 10 Gbps using a directly-modulated miniature planar-external-cavity (PLANEX) laser

In this presentation, the record results of a directly modulated PLANEX external cavity lasers (ECL), which has achieved 80 km transmission distances at 10 Gbps with a power penalty of only 1.4 dB, due to optimized chirp characteristics are presented. The ECL has been miniaturized and integrated into a TOSA applicable for industry standard XFP modules, and is directly applicable to DWDM operation due to the use of a PLC based Bragg reflector
