We propose a novel ONU power-saving scheme called single-handed type ONU power saving scheme. Proposed scheme does not require any power saving functions in EPON OLT. We also present evaluation results of proposed scheme.
We propose a 10.3 Gb/s burst-mode XFP transceiver with an emphasis for 10G-EPON multi-port OLTs. The burst-mode receiver sensitivity of −30.4 dBm with FEC was achieved with a 250 mm long transmission line to the XFP, peak emphasis gain of 3.5 dB and burst-mode CDR.
We have experimentally demonstrated 2.5Gb/s C-band burst-mode upstream transmission for TWDM-PON. Using high launched power from a +4.0dBm DFB-LD with low chirp characteristics giving less than 0.6dB penalty after 50km transmission, we could achieve the target split ratio and transmission distance of NG-PON2 (1:64 split, Transmission distance > 40km).
Performance evaluation of 10G-EPON system with dynamic bandwidth allocation (DBA) is described. We confirm the priority control function of proposed DBA, and the improvement of 15.4% total MAC throughput with 240ns SyncTime employing burst-mode XFP transceiver and burst-mode CDR in 128 subscribers environment.
We review recent progress of burst-mode CDR technology as the key PMD device supporting next-generation, 10 Gb/s-based TDM-PON systems. For the essence of the burst-mode CDR design, its performance result of the burst-mode lock-time is also presented.
This first Extended 10G-EPON uplink system test achieved the largest access span loss of 37 dB supporting 512 ONU splits over 25 km with an enlarged loss budget of 51.2 dB via wide linear gain region burst-mode SOA, RS(255, 223) E-FEC and burst-mode 3R.
This first super-splits 10G-EPON demonstration achieved the largest loss budget of 35.9 dB and a fast dual-rate synctime of 240 ns supporting 256 ONU splits with 8.0 Gb/s upstream throughput, highlighting novel self-switching AGC based XFP, 82.5 GS/s CDR and ONU SFP+.
