25-Gbit/s 100-km Transmission using 1358-nm-wavelength SOA Assisted Extended Reach EADFB Laser (AXEL) for 25 Gbit/s-class PON

25-Gbit/s non-return-to-zero (NRZ) transmissions were successfully extended to 100 km by using a 1358-nm-wavelength SOA integrated EADFB laser (AXEL) with an optical modulation amplitude (OMA) over 10.5 dBm.
