Bandwidth Growth Promotes NG PON Development

2

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?
