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
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

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
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
