Bandwidth Growth Promotes NG PON Development

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)

A short history of PON
� 1994: pi-PON. 50 Mb/s, 1310nm bidirectional, circu it switched
� 1999: A/B-PON. 622/155 Mb/s, 1550nm down, 1310nm up , ATM-based
� 2004: G-PON. 2.4/1/2Gb/s, 1490nm down, 1310nm up, packet-based
� 2009: NG-PON1. 10/2.5Gb/s, 1577nm down, 1270nm up, packet-based
� 2014: NG-PON2. 40G+ capacity… but how? (and when?) ( and why?)

Protocol and management of NG -PON2
� Mainly, NG-PON2’s protocol (the TC layer), manageme nt
(the OAM layer), and the service architecture (TR-1 56) is
the same as XG-PON1 (similar to G-PON)

So it’s a PON over DWDM, so what?
� Activation in multi-wavelength,
multi-operator, multi-vendor
case is non-trivial
� No link engineering allowed
� Worst-worst-worst case assumed
� Interoperable specs required
� If ONU is not calibrated, how
can it learn without jamming
others?
� Synchronized ranging windows?
� Very weak “photon ranging”?
� PON is different from DWDM
� No mux on the ONU side
� Extreme dynamic range
� ONU’s must have spectral purity
� The system to support DWBA?
� Downstream tuning is slow
� Upstream tuning medium
� TDMA is very fast
� Burst mode tunable lasers
� Power -> Temp -> Wavelength

Markets to watch for driving NG -PON
� Large MDU and FTTdp (G.fast) deployment� MDU applications have high aggregate bandwidth for each ONU � Also a low sensitivity to optical interface costs (optics are shared) � MDU and FTTdp are therefore a reasonable first step for NG PON
systems� Wireless backhaul and fronthaul
� Wireless demand is exploding, and 5G is coming� In rural areas, 4G and 5G may become the defacto answer� Effectively, this becomes FTTnode with wireless drops
� Network rebuilds � The main body of deployments are G-PON and 1GE-PON� However, before those systems, there was B-PON� This base of B-PON is nearing EOL, and will need replacement
� Network extension� First optical deployments took the “easy ground” � There is still 50% of the territory uncovered…
… but it tends to be less desirable� Can next generation technologies help by more fiber sharing?
