Next Generation FTTx: Optical Fibre Innovation as an enabler
Please CLICK HERE to give us your feedback on this webinar
The global path towards offering high speed broadband via fibre to the home has, at its root, the driver that subscribers want to live in a super-connected world and so want the bandwidth to enable it. Hence the telecoms industry is striving to deliver fibre to the home and 100G data rates to increase capacity wherever there are bottle necks, such as in the core or the metro-core..
In this webinar, we reflect on the modest technology that is at the heart of this fast evolving communications industry: the optical fibre. It is a little heralded fact that fibre is fantastic, without optical fibre all of this would not be possible: hence it is fair to say that the optical fibre is the fundamental enabler of all modern day telecommunications networks.
But what can the modest optical fibre do to help us enable a future ever more connected world?
This webinar brought to you by Telecoms.com in association with Corning Optical Fiber covers:
- - Key Broadband market drivers in Access Networks and how these challenge your optical network including; Open Access Architecture, Rural Coverage, Central Office Consolidation, System evolution and Fibre in the Building.
- - Optical fibre innovations as an enabler on each scenario: standards and performance.
- - Next generation access networks: how advanced fibres extend your reach and expand your possibilities.
- - Fibre in the Building: using fibre innovation to get it right first time, lower OpEx and enhance the connected customer experience.

Can you quantify the financial benefits of using a G.657A3 fibre for indoor cables?
We did a case study for a European operator that had used G.657.A1 in their indoor drop/horizontal cables. They were having problems with customer disconnection that was causing high levels of churn and reducing their ARPU. The study showed that using G.657.A3 fibre instead of G.657.A1 fibre in their drop cables would greatly increase the reliability of the customer connection and yield savings/increased revenues in the following ways 1) 10% cost savings due to decreased install time 2) 20% costs savings from removal of need to install protective duct 3) 25% cost savings due to reduction in maintenance costs – fewer truck rolls to repair high loss events 4) 45% savings (actual net revenue gain) due to increased customer satisfaction – less churn – that delivered higher ARPU. Surprisingly the fact that the improved connection reliability increased ARPU was the biggest and yet least tangible/predicted impact of using the G.657.A3 fibre that was revealed in this study.

Hi James,
is this webinar saved befor and now it’s look like a chat room
Yes, the webinar is saved/archived. In fact the archived version is available now on this page. We’re getting a lot of questions coming in and some good discussion going, as you can see.
In countries where 4G/LTE is prevalent – are we seeing any customers cancel their fixed line connection in favour of a wireless only connection?
Although 4G/LTE offers much greater mobile data rates than previous technology like 3G, the data rates that can be offered via true FTTH be PON or P2P are significantly higher and hence more attractive.
It is only in areas where wireline access and connectivity is very poor (e.g some areas in Africa where getting a fixed line or high speed data service over a fixed line is not possible) that mobile internet may be preferred over fixedline. However even in those situations optical fibre is the key enabler as it provides the high speed backhaul necessary in the core network in order to facilitate backhaul of the mobile traffic. For the backhaul network, low loss fibre can enable higher data rates, longer system reaches and a reduction in system equipment costs.
How would you propose the benefits gained from replacing recent and existing fibre installations with the SMF-28e+ LL.
When you install low loss SMF28e+LL fibre you get immediate benefits from lowering the attenuation of link lengths in your network: so you can extend your link lengths to cover more customers or have the flexibility to upgrade to higher data rates or do central office consolidation with less compromise on your original network design
What evidence is there of consumption/behavioural changes in leading FTTX countries when they migrated from ADSL i.e. are they consuming materially different applications or just consuming the same but faster?
This will vary greatly from country to country. But I would suggest looking more closely at Denmark which I understand has a highspeed P2P fully optical fibre enabled broadband access network with good population coverage. Here I understand that access to high speed optical fibre enabled broadband has changed the way people work and do business. Sweden is also another good example to study in this regard.
Hello,
SMF-28e is most suitable for CWDM solutions, am I right? What about DWDM and possibility of splicing with standard G.652 fibres – what are the impacts when connecting them together – any significant dispersion happens?
Thank you
Corning’s new low loss G.652.D fibre, SMF-28e+LL shares all the same attributes (including dispersion) as SMF-28e+ except for lower attenuation and lower PMD: both of the latter being good for advanced system performance. SMF-28e+LL has a Low water peak just like SMF-28e or SMF-28e+ and so is also perfectly suited to CWDM solutions. The new loss loss SMF28e+LL and is totally backwards compatible with SMF-28e+ (Corning’s current standard G.652.D fibre product) and so has the same high quality splice performance with no issues of splicing SMF-28e+ LL to SMF-28e+ or any other G.652.D compliant fibres either.
With advances in wireless/mobile data rates e.g LTE, 4G and by effective integration of wireless into high speed wireline broadband access networks for mobile backhaul via cell towers placed and integrated at regular intervals in the access network, greater mobility will be enabled
Why can’t we use our 1310nm and 1490nm wavelengths for 10GPON?
This is because the standardised wavelengths for 10GPON have been chosen so as to not overlap on existing GPON wavelengths: as a result both systems (GPON and 10GPON) can co-exist and run in parallel on the same network
Thanks and very interesting presentation
Hello, i am an expert in a regulatory and in my country it is survaying to implement a broadband access network by FTTX. i have some question about FTTX.
1-the average budget to implement a metro in a city of 40×40 kilometer with around 15 million poeple?
With a population of 15million several central offices will be needed to serve all. The power budget and therefore possible system reach depends very much on the topology you use be it PON, P2P or FTTC. Within each of those topologies there are often different grades of system that offer different reaches. The key thing here is no matter what technology you use using a low loss fibre will extend the reach of your system / enable you to run at higher data rates / achieve higher coverage / easier migration to central office consolidation in t he future
Hello there. Can you tell me how can low loss fibre help in an existing network compared to a Greenfield build?
Wherever you replace a section of G.652 fibre cable with a low loss section of cable in an existing network, the net effect will be that you bring the average attenuation of your network down. To begin with the average attenuation will be higher than that of a purely SMF28e+LL network but in time as you replace more cable sections with low loss fibre cable you will eventually achieve a full next generation enabled low fibre loss network. The sooner you start the sooner you get there!

Hi Christian
Thanks for your question
Slight nuance on the position, a proposal has been made to the European standards group, Cenelec, that an optical budget for indoor cabling is adopted. I understand that the initial proposal made to Cenelec was for 1.2dB. I believe it is still in review with a formal decision yet to be made but the expectation is that it will be 1.5dB or lower
The proposal is available via Cenelec
