| Abstract | Abstract—We propose and demonstrate a 40-Gb/s sym-metric passive optical network with a high split-ratio of 64. The upstream 4 10 Gb/s signal is produced by using a di-rectly modulated, uncooled 1.55- m monolithic integrated vertical-cavity surface-emitting laser array. The downstream signal is a single-channel 40-Gb/s dark-return-to-zero (DRZ) data, broadcasting information to different optical networking units (ONUs). As the ONU is cost-sensitive, we also demonstrate, by means of simulations, using a 12-Gb/s receiver at the ONU to receive the 40-Gb/s DRZ downstream signal. Index Terms—Fiber-to-the-home (FTTH), passive optical net-work (PON), vertical-cavity surface-emitting laser (VCSEL). I. |
