ITU Give Consent To New 40Gbps Fiber-to-the-Home Broadband Standard
Mark.JUK writes: The International Telecommunication Union has just granted first-stage approval ("consent") to two new ultrafast Fiber-to-the-Home (FTTH) optical broadband standards. The first (NG-PON2) will support Internet download speeds of 40Gbps (Gigabits per second) and on top of that the new XGS-PON aims to deliver a symmetric 10Gbps service (same upload and download rate). By comparison, the previous XG-PON standard only ensured an asymmetric speed of 10Gbps download and 2.5Gbps upload. Now all we need is computers, Internet services and Wi-Fi networks that can actually harness such performance in the first place.
Nobody needs more than 640kbps.
First we need ISPs to provide broadband service.
We can't buy it if they won't sell it.
Minimum threshold fixed. Thanks!
Fantastic! Yet another high-speed standard that will be completely ignored by the telco oligopoly here in the US. At least Europe and Asia will benefit.
Slashdot still doesnâ(TM)t support Unicode after it was added to the HTML standard in 1997.
WDP-PON is 40Gb split 32 ways with a dedicated 1.25Gb per end point
XG-PON1 is 10Gb down 2.5Gb split 32 ways, non-dedicated but up to 10Gb per device
XG-PON2 is 10Gb down and up split 32 ways, non-dedicated but up to 10Gb per device
TWDM-PON is 80Gb down and up split 32 ways, non-dedicated but up to 10Gb per device
NG-PON2 is similar to TWDM-PON, but caps out at 40Gb for the current implementation. Where it really stands out is the standard should scale up to 25Tb/s with 100Gb per customer. This makes it desirable for a smooth upgrade path into the far future.
TWDM-PON can actually split up to 128 ways. Most PON standards support at least 64. 32 way splits are just a conservative approach that many ISPs take. None of it really has much to do with how much bandwidth you can sell in practice. Most ISPs are going to hit backhaul and IP drain limitations long before they congest any of their PON access layer.

TWDM-PON only supports 128 way split. GPON only supports a 64 way split. Many ISPs are conservative and only do a 32 way split on GPON anyway just to give themselves more leeway for fiber defects.

Fuck, I just got Gigabit FTTH last week... And now you're telling me it is already outdated and that I need to upgrade to 40gbps!?!? Well SHIT!
