Re: Vodafone Ultrafast/Gigafast (Cityfibre 1Gb rollout)


[re: MrSaffron] [link to this post]
 
In reply to a post by MrSaffron:
The CityFibre model very much relies on not using BT Group fibre assets, i.e. they push dark fibre via their metro networks - which is a bit different to the GPON Vodafone roll-out but tells you a lot about the core network.


Can you expand on that please? Are you saying that you suspect the Vodaphone/City Fibre team-up is not the same product as the other City Fibre offerings?

Vodafone Gigafast is GPON

Most other business metro network type services are point to point fibre, with dark fibre i.e. you light at whatever speed takes your fancy

So yes Vodafone Gigafast is going to be very different to the core product which is the large council building network links etc

So yes not all full fibre is created equally

Thanks.

So how does that impact the earlier question of separate infrastructure? I have read that the telephone element of Vofafone’s Gigafast offer is actually VOIP. I have also read that jitter, buffer bloat, and more specifically 100ms of latency starts to cause problems for VOIP, so you would expect the service would have to be particularly stable in terms of quality to avoid jitter?

So contention at peak times would also need not to be an issue. Do you know what minimums are guaranteed, in comparison to FTTC? If I remember correctly it is 15Mbps with Plusnet, as I am currently close enough to the cabinet.

I read about Vodaphone Gigafast here.

i.e. the two infrastructures are separate and is a key part of the low cost of roll-out they are aiming at

If a full fibre voip service cannot get VOIP latency under 100 ms then it will not exist for long and would very quickly become a white elephant. i.e. no reason why latency for voip should be any more than any other FTTP service.

Contention at peak times - that all depends on a lot of unknowns. Guaranteed speeds not seen any mention of them.

NOTE: The PlusNet 15 Mbps is only across the Openreach controlled segment, once you hit the handover node that figure is history.

NOTE: VoIP can have very different guarantees compared to Internet traffic.

There's been a few reports of Vodafone FTTC services (even using their own backhaul so nothing to do with BT Wholesale) slowing down at peak times so let's hope their FTTP service performs better. Will be interesting to see if their own backhaul fibre (ex-C&W) is also used for FTTP connections or if it will be be 100% CityFibre fibre all the way to Vodafone's data centres. Obviously fibre from the home to the nearest PoP/exchange will be Cityfibre's network.

They have been working on my street In Bletchley and the one at the end for the last week. Digging up the footpath and laying new cable. Streets are a bit of a mess but hopefully will be worth it.
