10 Gigabit demonstrated over Openreach FTTP line
Thursday 08 November 2012 18:09:21 by Andrew Ferguson

Yes this is just a technology demonstration by ZTE and Openreach, but being able to run 10 Gbps over a PON architecture fibre link shows that there is a long lifespan in the architecture the local loop provider has decided to deploy for its FTTP service.

The demo took place in Cornwall running over the top of an existing 330 Mbps FTTP service that Arcol has in the county. The XGPON standard is still pretty new, with Verizon testing a pre-standard Huawei version on its FiOS service back in 2010.

While a 10 Gbps service for areas with FTTP is some years away, it is very likely that in 2013/2014 we will see trials of a Gigabit service from Openreach. Gigabit fibre services are already available via Openreach, but these are dedicated Ethernet services that include greater commitments to repair faults quickly and usually uncontended bandwidth, thus making them too expensive for the average youtube uploader or SME.

Bring it on!

People slate the fttc rollout but that is the enabler to move to tech like this , it's not a dead end it's the start of a new chapter for broadband

I struggle with that a bit.

Having read the documentation it looks like the only bit getting reused in the FTTPoD deployment is the fibre running to the cabinet.

The MSAN, the optical hardware in the cabinet, the power supply, the cabinet itself indeed are not involved.

The duct network being maintained and fibre blown to nodes is the key. It's an enabler from the Openreach bean counter POV, unsure about any other persepctive, welcome correction.

The bit that gets re-used from FTTC is the fibre spine, so FTTP on demand connects from the premises to the aggregation node (as you say not the cabinet itself), just as FTTP does, well its the same product

So what I'm saying is without that fibre spine that FTTC put in place FTTPoD would not be possible
Posted by Dixinormous over 4 years ago
So blowing fibre to neighbourhoods was the only key. In many cases fibre is already really close and indeed proximity of spine seems to be a major decision maker for Openreach.

I was expecting some of the 31,000 active, powered cabinets to be reused in some way, be it hosting line cards or whatever.

As it is they'll end up with an OLT in the exchange, splicing into the backhaul MSAN fibre in the cabinet, thus bypassing cabinet entirely, and delivering from there.

FTTPoD is going to be phenomenally expensive, a clever way to get people to pay for BT's network upgrades though!

Yes it will be interesting to see the price for it I mean, for a small business it would be a great investment, even for a home if you can stomach it, once the fibre is in your set for the future, only your OLT could need replacing in the future. The thing is I would expect people to pay for FTTP though, people shouldn't expect it to be a free install or cheap as there's more to do. I just hope its not prohibitivley expensive on the install charges
Posted by GMAN99 over 4 years ago
I'm sure as time goes on the charges will (have to) come down otherwise no-one will buy it although I doubt many would anyway for years yet if they have FTTC
Posted by Dixinormous over 4 years ago
The pricing structure will be key. Do Openreach make the first subscriber to FTTPoD on the cabinet pay the full planning and build costs then charge other people the standard install fee?
Posted by GMAN99 over 4 years ago
No idea, I guess that is what the trial is about, you are right in your thinking though, once one customer brings fibre to a street and to a pole most of the grunt work is done, another customer on that same pole (or even street depending on how they do it) needs a lot less work so it is much cheaper to do. It seems harsh charging the first person in full whack, you'd like to think they'd swallow some of that themselves but then.... I can't see take up of this being high for many years so if they did swallow some of that initial build it could take ages to get it back.
Posted by GMAN99 over 4 years ago
I mean for me, if my pole had fibre on it as someone a few doors down had fibre I'd be expecting to pay sub £100 for the install wouldn't you? That would be very attractive indeed, but I'm not sure how its going to work really I guess we'll know next year.

How the charging is split is part of the trial, as in learning whether when one neighbour has it are others more likely etc
Posted by Dixinormous over 4 years ago
If it works the same way as the FTTC rollout has in many ways who knows?

OR have in general been spending as little as possible to pass as many homes as possible as quickly as possible rather than spending more and going for a higher take up rate. Something that is a major irritation for ISPs who find themselves struggling to sell their products to consumers who already have good ADSL 2+ options.

However with taxpayers' money available to cover the more expensive areas who wouldn't?
Posted by PeteK over 4 years ago
The biggest problem of course is the circa £40Mb/s hand off costs from BT to the ISP...

This is going to be a problem until the next "killer app" that requires oodles of bandwidth.

Too much make do at the moment, demand by the majority of the population will be driven by a real need rather than nice to have.

and what will the upload be on that gigabit service?
Posted by andrew (Favicon staff member) over 4 years ago
Gigabit Openreach - lets look into the crystal ball and suggest 100 Meg

So does FTTPoD connect to the roadside MSAN or it just a GPON fibre delivery down the same duct to the exchange ?

As the FTTC MSAN has a number of dedicated fibre pairs feeding it then I can see how it might struggle with the capacity issue, but if FTTPoD is in parallel it does mean that the presence of FTTC is at best a marketing precondition.

FTTPoD appears to go right around the cabinet housed MSAN herdwick.
