Re: How big are VM's infills?
 

If it's an " infill" I.e an area surrounded by existing network, was planned to be built back in the day but never was. Then it will likely be HFC.

If it is new areas beyond what was the original planned footprint then it's a good chance it will be fttp and therefore RFoG.

VM are not really looking at GePON at the moment, they were looking at doing it.

They were actually looking at providing fttp in Cabled areas separate from HFC, similar in how fibre 10G circuits are offered to business.

Re: How big are VM's infills?
 

My opinion is that is the way to go!

Re: How big are VM's infills?
 

Wouldn't it need different set top boxes and routers though?

Re: How big are VM's infills?
 

Too expensive. Comcast have done this but only delivering FTTP when ordered, not to replace existing service. Delivered as Metro Ethernet, so point to point fibre between home and customer.

Expensive, long contract, high install charge.

CenturyLink used the existing coax to pull through a new coax + fibre drop and sold 1Gb over GPON. Lower pricing and more of an FTTP on demand scenario. Eases load on the existing HFC plant by overbuilding it when heavy users stump up the money.

If you're referring to RFoG, no. An ONT in the home converts the fibre to coax for distribution to existing STBs and hubs.

In the case of the Metro Ethernet solution existing coaxial drop carries the TV, a new Metro Ethernet switch terminates the new fibre connection and connects to a customer's own router much as modem mode on a Superhub works.

Also fibre intensive, you need a fibre pair from the customer location back to the head end.

Still ,It was being looked at so they could claim the country's fastest broadband tag.

RFoG is a bit pants IMO. But it enables fTTP roll out without wholesale change to the VM network delivery and as I see it, at least the fibre infrastructure is at least in place and other solutions can be delivered over it in the future should things change.

Re: How big are VM's infills?
 

Why a fibre pair? Is VM buying cheap low quality fibre that can't deliver the same as anyone else's???

Re: How big are VM's infills?
 

I don't doubt that, I was looking at it purely from a technical perspective. RFoG essentially has the same bottle neck as HFC, the CMTS port. As things progress that will become less of an issue, but FTTP should be some to shout about, with vastly improved upload

Re: How big are VM's infills?
 

Que?

One fibre to transmit the other to receive?

They can relatively easily remove the bottleneck and put other things over the fibre without affecting RFoG which is nice.

Can happily use the same fibre to deliver DOCSIS to regular users while Team Torrent can, for a price, be offloaded onto a PON solution.

Re: How big are VM's infills?
 

No I was referring to FTTP

I'm assuming the second paragraph explains how FTTP would work if Virgin were to do that?

Re: How big are VM's infills?
 

That's how the solution Pierre mentioned would work, yes.

RFoG is also FTTP, mind you.

Re: How big are VM's infills?
 

I'm no longer a network engineer Igni, but I still want to keep my knowledge up together so I'll keep an eye on yours posts in future and see what's going on, as well as keeping in contact with my old team to hear the latest!

Re: How big are VM's infills?
 

Your old team are likely the best source of information.

Much as moving back to ISP-world and broadband interests me I'm probably a little too expensive for VM given my skillset so not going to be back in that frame any time soon :)

Re: How big are VM's infills?
 

Sweet.

Re: How big are VM's infills?
 

From what I can gather the product is selling pretty well here.

The wait for an install is nearly a month.

Re: How big are VM's infills?
 

Blimey, 3 months ago the digging was done in some streets, still no homes live due to a couple of issues.

Problem with getting power to a cabinet and problem getting a fibre cross-connect between a couple of telco MSANs.

Neither an issue with FTTP. Perhaps a pity it was planned so long ago! :)

Just as a thought, didn't really read this earlier, could fire quite a few Gb down a single fibre via PON.

The latest and greatest would allow symmetrical 10Gb to each subscriber and co-exist with RFoG, GPON, XGPON. The ONT and OLT are probably scary expensive for right now, though.
