Ireland is an interesting market to focus on, as FTTH deployment in Ireland involves different players, varying types of population densities and different architectures and deployment methods. The very competitive market structure in some parts of the country is countered by government involvement to improve the infrastructure for rural areas. Eir’s Senior Access Strategist, David Renehan will explain how they handle all these difficulties and will highlight their learnings from the project, while experts from Comsof and GE dive into specific issues in the planning and deployment process. This is the presentation from a workshop at the FTTH EU Conference 2016 titled "Learning from Real life cases - key success factors during preparation of a FTTH rollout" organized by iMinds, GE and FiberPlanIT.

25. Best practice: Importance of input data
James Wheatley
25

26. Importance of data quality
 Result of analysis dependent upon quality
of input data used
 If re-using existing infrastructure then need
to utilise existing network data
 Is that data complete and accurate?
 Data quality becomes critical during low
level design
 Low data quality will result in poor designs and
increased construction costs
26
Investment in good quality data saves on overall project costs

27. Network inventory as the data source
 GIS-based network inventory solutions
provide natural repository for data
 Particularly for expansion or over-build of
existing networks where re-using existing
infrastructure
 In greenfield deployments using network
inventory as data repository from the outset
provides benefits when network build is
complete
 Support for other process such as service
assurance and service fulfilment
27

28. How to improve data quality
 Desktop survey
 Use satellite imagery, street level imagery & LiDAR to
improve input data for first pass low level design
 Field survey
 Take initial low level design out into field to verify and modify
 Eliminate risk of changes to design occurring during
construction – often invalidates optimisation resulting in cost
overruns
 Eliminate paper from data round trip to streamline process
 Manage process with work management solution

29. Why publically available data might not be enough?

30. Other data field surveys can collect
 Address verification
 Sub-divided land parcels
 Verify deployment methods
 Aerial, underground or on-building
 Pole availabilityquality
 Accessibility of manholes and poles
 Duct quality and availability
 Identify and record potential health &
safety issues

Ultimately only field survey can identify all design risks

34. Case study: Balance between Cost and Revenue
34
Scenario 1: Maximal Coverage
“Deploy in cheapest areas (high density) until
reaching 8M EUR deploy cost”
#HP = 17.150 (= 48,8%)
Cost per HP = 465 EUR
#HC (Y10) = 5.840 (= 34% of HP)
Total Revenu = 8,9M EUR
Scenario 2: Maximal ROI
“Deploy in areas with highest ROI until
reaching 8M EUR deploy cost”
#HP = 14.400 (= 41,0%)
Cost per HP = 553 EUR
#HC (Y10) = 6.560 (= 45% of HP)
Total Revenu = 10,2M EUR
Same investment
More Coverage Less Coverage
Less Customers More Customers
Less Revenue +13,5% More Revenue

35. Areas with competition
Go for FTTH
 Better offer
 Impact on adoption rates
 Still attractive
 Overbuild
Time to market!
 Design automation
 Advantage existing conduits/poles

36. Rural and Urban deployment at Eir

37. Rural broadband in Eir
Two years ago eir carried out detailed analysis on it’s rural network (mostly aerial cable) to determine what
was the most cost effective and scalable technology to deliver rural broadband nationally across a rural
landscape that was made up predominantly of ribbon development housing (houses built alone the roads
and not in hamlets).
 FTTH/GPON was the technology of choice ahead of FTTC/FTTN/FTTB/FTT-dp or LTE.
 After careful analysis eir have chosen a cascaded two stage splitter architecture for rural FTTH (1st stage
splitter = 1:8 2nd stage splitter = 1:4).
 eir set up a team to evaluate existing overhead fibre work practices to reduce costs per KM.
 eir chose a All-Dielectric Self-Supporting (ADSS) fibre cable as the best choice for aerial cascaded splitter
FTTH delivery and also the ADSS cable had the added advantage of reducing the number of OH/UG transitions
at electrical crossings.

38. Rural broadband in Eir: Trial
In 2014 eir built its first trial rural FTTH network passing over 150
homes as a proof of concept to determine:
 The new access fibre work practices worked in the live network
 ADSS fibre cable was suitable for eir’s splitters/splicing & DP closures.
 Planning and GEO tools could record and manage the new rural FTTH
architecture.
 This was a huge success and proved useful to both eir and the rural
communities as to how FTTH could change their lives
In mid 2015 eir built a second trial rural FTTH network passing over
120 homes to fine tune the outcomes from the first rural trial:
38

39. How Eir accurately costs urban FTTH/GPON
Eir first trialed FTTH in two urban exchanges in 2008:
 These two urban FTTH trials used a distributed 1:32 splitter architecture.
 The trial had a total of 1500 active FTTH customers and passes 10K homes.
Lessons learned from NGA rollout to date:
 Eir rolled out fibre to almost all its urban copper cabinets over a 3-4 year period.
 This large scale fibre rollout drove huge changes in underground fibre installation work practices and the
introduction of wide scale sub-ducting in the urban NGA network. We now have a proven cost model for:
 Cost of installation of sub-ducting per metre, clearing blockages etc.
 Cost of splicing per closure (different size cables etc.).

40. How Eir accurately costs urban FTTH/GPON
Using planning tools to accurately cost future FTTH projects .
 Using eir’s FTTH planning tool and GEO analysis tools it is now possible to take the
learned costs and accurately produce a details BOM per new FTTH planned area.
 These tools can run various scenarios to evaluate what are the best FTTH rules to
apply to design the most efficient splitter/homes passed model and reduce
infrastructure costs.
40

41. Identifying commercially viable FTTH rural areas
Eir has spent the past few years analysing both urban and rural
access infrastructure.
Using GEO tools, Eir have mapped every premises in Ireland and
identified whether they are urban or rural and what exchange they
are served from:
 Is the premises served from an NGA enabled exchange?
 Is the exchange fibre enabled?
 Distance from exchange?
 Exchange density?
 Total length and type of existing cable infrastructure?
41

42. Identifying commercially viable FTTH rural areas
Using automated FTTH design simulators, GEO tools and an in
house algorithm it was possible to derive the cost H/P per dwelling
using various rules e.g.
 Cost per exchange area?
 Identify most cost effective routes per exchange?
 Identify most cost effective routes nationally?
 Launch from fibre enabled exchanges only?
 Etc.
From the above information it is now possible to calculate a detailed
BOM for any rural FTTH route and classify it as commercially viable
or not?
42

43. Something to remember?
 Learn from trials and earlier roll-outs
 Get accurate view on difficulties and costs
 Involvement of government in rural broadband
 Use tools for accurate cost estimations
 Save costs by reusing infrastructure
 Importance of data quality
