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


� 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

WDM PON Overlay

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


� 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
