Next Gen FTTH

No, Sorry. Our distribution switches only support 40GBps Symmetrical point to point.

Still a bit faster than 10GBps split 128 ways with 50% upload speed, no?

Hey, not arguing AE can go high, I did not knock AE, but I said look at the speed and technology, did you actually look at the video and see the technology, there is a place for AE and PON technologies, but some people just ware blinkers.

Well you can always take a NGPON2 10Gbps single fibre and split 10X for 1Gbps guaranteed to each home, i see nothing wrong with that and NGPON2 is symmetrical not 50% upload as you state.

Then with NGPON2 you can take 4X wavelengths to give you 40Gbps over a single fibre...not much different to the active Ethernet you raving about, especially when you thinking FTTH. The problem with AE is when you take that 40gbps pipe and want to split it to subscribers, you require active, powered, expensive switches where as with NGPON2 you use a simple passive splitter in a manhole.

Where AE dominates is the ability to use DWDM, then you talking multiple 40/100Gbps channels on a single fibre...but it works out too expensive for FTTH nor is it necessary.

Aah the AON vs PON debate. Everything has advantages and disadvantages. A good document to read on this topic with some cold hard facts is this one: http://htkh.netcenter-vn.com/tailieu/aonvspon.pdf

Thank you for the link, it is a bit out of date though, I also don't want to get into the AE v PON argument as there are reasons why you would use both, the fact is that today GPON systems are delivery 1GE services from operators such as Google and century link. remembering that as the speed gets higher the actual bottle neck is the backhaul capacity,

very well put,

and in fact you can get 8 X 10G on NGPON2, the demonstration was only 4.

Well there you go...8X 10Gbps for 80Gbps on a single fibre...I would say that is pretty much future proof...the only thing that has to happen now is for mass adoption so that the NGPON CPE/ONT devices become cheaper, for now it is most likely to be used for FTTC/FTTB and not FTTH, still very exciting technology, i really believe the future is WDM, where every subscriber gets a dedicated wavelength as opposed to PON which i think uses TDMA
 
NG-PON2 demo from Calix

Published on 5 Nov 2015

Shown at the 2015 Calix User Group Conference, Calix engineer Chris Bernard demonstrates new 10 gigabit PON technologies XGS-PON and NG-PON2, as well as co-existence between the new technologies with GPON.
