NG-PON will be necessary if bandwidth requirement of per end user beyond 100Mbps
Optical access will evolve toward 500Mb/s~1Gb/s (long term)
Toward Giga-bits-per-second Access

Requirements of Future Broadband Access
� High Bandwidth, large split and long reach• ≥ 40Gbit/s aggregate capacity
• Sustainable 500Mb/s~1Gb/s per ONU
• Large splitting ratio with 64 ~1000 ONUs per feeder
• 20 ~ 40 km reach (passive)
� Legacy optical distribution network compatibility
HUAWEI TECHNOLOGIES CO., LTD. 6
� Open access on layer 1 and layer 2
� Better resiliency and enhanced security
� Low power consumption and high port density
� Applications for converged services
• residential, business and mobile backhaul/fronthaul
* source: FSAN operators’ requirements

• Technology: hybrid time and wavelength division multiplexing
• Bandwidth: downstream 4 (or 8) x10Gb/s, upstream 4 (or 8) x2.5Gb/s
• Coexistence: backward compatibility, no change in outside fiber plant
• Flexibility: wavelength tunability enables ONU operating on different lambda’s

Conclusions
Conclusions
� Pluggable transceivers for TWDM PONs are developed for
future large scale deployment
– Integrated OLT transceiver module in enhanced CFP package
– Low cost ONU transceiver module in SFP+ package
– 40km reach and 36 dB power budget for ODN class E2
HUAWEI TECHNOLOGIES CO., LTD. 25
� WDM PON overlay using self-seeded RSOA is demonstrated
– WDM PON overlay with minimum modification of ODN
– Low cost self-seeded RSOA for OLT and ONU
– 16x1.25Gb/s is demonstrated with 40km reach; 32x2.5Gb/s is possible
