Please explain the difference between ADSL vs VDSL vs Fibre

[maumau]

Is VDSL just a faster version of ADSL and why is fibre better than VDSL?

The reason I'm asking is we can get VDSL but everyone's motivating for Fibre (fiber?)

Thanks

ADSL2+ < VDSL < Fiber

ADSL and VDSL are over copper, ADSL is 20Mbps and below, max 1Mbps upload if on 10Mbps, else 512Kbps. VDSL is 20 or 40Mbps, 2 or 3Mbps upload. ADSL has about 15% of line used for overheads (you will never get 10Mbps, but rather ~8.5Mbps).

Fiber is the future, lower latency, less noise issues, less maintenance, faster speeds for cheaper (depending on the provider), no loss in maximum line speed due to distance as well.
If you can, always go the fiber route. Fiber also allows a lot higher upload than ADSL/VDSL, this is especially useful for businesses when they want to have video conferences/file backups.

In simple terms, VDSL uses the same copper lines as ADSL which makes it prone to to the same issues ADSL has with outages due to cable theft. Fibre uses a plastic cable which has little resale value so in theory, thieves wouldn't have much use for it.

Fibre is also more stable at distance from the connection point to the main network i.e. attenuation is less of an issue over distance. Fibre also has the capacity to carry more data instantaneously (bandwidth) than copper.

Thanks guys, so the crux is that fiber won't get congested and you get full speeds. In which case i can see why it's the shape of things to come like Johnatan56 says.

Will that still apply if, say TV, was delivered via fiber instead of satellite? Or would it get choked?

Contention for back-end bandwidth would still apply regardless of how much bandwidth your personal fiber connection could deliver. By this I mean it's still possible your provider could over-subscribe his network and cause some congestion. However, this is way more unlikely with fiber than ADSL.

Thank you MickeyD. Those vids look as if they'll explain well.

Satellite would be great for downloading things on a clear day, but then you have latency, which is about 6 seconds, so all right for a stream if nothing real time is ever needed.
Fiber can get congested at the exchange as others have stated. MickeyD has posted some nice vids on the different types of FTTH. Fiber has the lowest latency possible for all of the types of internet access, so it would be the most preferred for any internet usage. Fiber is also cheaper than Satellite.

Thank you, you guys rock

Was looking up that GPON yesterday but it's easier to understand on video.

Hopefully they're all laying fat fiber that'll last for years.

Satellite....

Is your ultimate LAST resort if you do not have access to any other type of cable or wireless network.

Would never have thought that.

 

[Neoprod]

You never want satellite for anything latency-sensitive (browsing, email, gaming, VOIP etc.)...the delay becomes very frustrating.

MickeyD - ta for the vids.

 

[maumau]

Enjoyed the vids, tks MickeyD.

Reminds me - throw LTE into the mix. LTE seems to have the best combination of availability, cost and performance if you're not living in a fiberhood. I intend to get LTE to replace my ADSL until my area gets onto the fiber bandwagon (or I move to a fiberhood).
