Vumatel to launch 10Gbit/s home fibre in South Africa

although XGpon and XGSpon are 10Gbit speeds, throughput is less than 9Gb/s due to overhead etc, it was designed so service providers could provide multiple 1Gb/s services of a single port.
Would like a source for that statement, you should be able to get close to 9.95Gbps?
 
2.5Gbps probably would make a lot more sense for home users as 10Gbps capable routers are in order of magnitude more expensive than 1Gbps capable routers. It is also near impossible for only a few users to max a 10Gbps connection as most CDNs seem to limit < 1Gbps, even lower in many cases. I would actually be more interested in a symmetrical 1Gbps connection, it would be more beneficial as I work from home and need to transfer large files often to AWS.

Source on this? I've seen a number of xgs-pon speedtests online where the throughput is above 9gbps.

Again, can you point me to the source for this?
Yeah, it's capable of doing that but was it designed mainly for that?

Got many questions

PON is a "shared bus" technology generally, so whilst XPON can approach 10Gbps it's shared amonst the many subscribers in the PON tree.

But isn't that why the XGSPON "tree" is usually capable of +100Gbps as to actually provide 10Gbps to the customer instead of rationed access?....and why and how would Nokia and Huawei be able to provide PON products that's 25Gbps and 50Gbps capable?

I mean an FNO wouldn't sell 10Gbps tier packages without being able to provide that speed to their customer clusters right.
 
XG-GPON aka (10G-GPON or XG-PON1) is 10Gbps download shared medium, and 2.5Gbps upload shared medium.

XGS-GPON aka (XG-PON2) is 10Gbps down, 10Gbps up shared medium.

25G/50G and up are newer technologies not fully ITU ratified and mass-manfuactured by vendors yet I believe.

Oh okay thanks

Although I believe Google is using Nokia's 25G tech in their new 20Gbps expansion. And I think Huawei is testing in Spain and Switzerland amongst other places...And since Vumatel and Huawei has an agreement, they'll probably be using the 50G pon tech, that's a neat future proof backhaul.

I get the whole shared nature of the PON technology but still not getting if "providing multiple 1Gbps services from 1 port" was actually the main reason for designing XGS-GPON since I'm seeing different reasons online.

If providers want to service more 1gbps users then they just add extra gpon OLTs, no? It's not like all the 1gbps subscribers on the tree will be concurrently maxing out their lines 24/7.

Also, providers that are currently implementing it (AT&T, Google Fiber, Starhub etc), are using it to introduce higher tier packages like symmetrical 2gbps, 5gbps and 8gbps+, instead of just upgrading to serve more 1gbps users.

I just want understand more :)

10-GPON was an upgrade of GPON, to increase bandwidth deliverable to the PON tree. It was also designed to be able to run along with GPON on the same fibre, on a different wavelength, so as to make the upgrade path easier.

Yes, but OLT's are pricey. They could also simply move 1Gbps subscribers to their own dedicated port on the OLT, but then it effectively becomes a switch.

GPON OLT interfaces are also not entirely cheap. But yes, the idea is that GPON can introduce some contention and sharing, as not everyone maxes their lines all the time.

We've had to get certain FNO's to move 1gbps subscribers to dedicated interfaces, as they couldn't always get their advertised 1Gbps.

Serving more 1Gbps users, and offering higher speed packages are drivers behind X-GPON upgrades. But it pretty much works like regular GPON just with higher speeds.

The typical "tree" split ratio for a GPON networks is 16-32 subscribers per GPON OLT interface or "tree", but of course it depends on the FNO's strategy and the area density.

I'm not aware of any major X-GPON installations in South Africa.

I see now, thanks for the detailed response.
 
I don't want to sound like the "Bill Gates 640kb is enough for everybody", but I really struggle to even fully utilise my 1Gbps at home, aside from the odd massive game download or "Linux Torrents."

I mean it's great to download 140Gb or so in 10-15 minutes, but it doesn't really happen that often. Most of the time my line idles around 10-40mbps peaks during regular usage in a household of 4 with pretty much streaming being our only major consumer of traffic.

As content size and requirements evolve 4K+ etc, I'm sure it will start creeping upwards in terms of requirements, but I haven't seen a major game changer that will realistically tax my 1Gbps service up to even 60-70% of capacity in a constant basis.

Unless you're downloading the internet. Or have specific requirements for major media upload/downloads such as is required for @jannier 's occupation.

I think there are more than a few of us working from home who would go faster if we could, even if we aren't the majority.

Tbh, that's a bad way to do business tho', don't tell your potential customer what they should want, give them what they say they want at an inflated price.

Do capitalism better Ro bro.

Not really telling anyone anything these are all just opinions right. If Vumatel offered it, then realistically so would we.

I never told anyone what they should want/need. Just gave my personal perspective and opinion.

We were the first to trial it and if it's commercially offered from Vumatel, we would certainly provide it to our customers.

Oh didn't mean to sound accusatory, was just saying it in jest.... although I do think the Vuma core network is mature enough to upgrade, they should've made their initial investment back by now. Multi-gig speeds would also unlock cheaper midtier speed at more reasonable (and profitable) prices for you guys. Pushing the price to 0.80c/mb would be great marketing and see a mark improvement in signups IMO. 1Gbps - R799pm come on now lol

Next up you'll be telling us "Linux Torrents" are cancer :ROFL: :X3:
