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

“World's fastest” FTTH
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

• 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
