This document discusses Eircom's use of FiberPlanIT software to plan and design its fiber optic network. Key points: 1. Eircom has invested 260 million Euros to build a fiber network passing 1 million premises, with a goal of 1.6 million by 2016. FiberPlanIT helps optimize this design process. 2. FiberPlanIT allows Eircom to automatically generate initial fiber designs, compare FTTH and FTTx scenarios, and accurately estimate deployment costs to identify high priority areas. 3. Eircom has used FiberPlanIT to reconstruct manual rural designs and generate new designs, finding the results to be very close to manual efforts but faster.

Introduction to eircom’s NGA network
• €260m invested in fibre access
network
• NGA passes 1 million premises
• On track to pass 1.6 million
premises by June 2016
• FTTC, Vectored VDSL, up to 100
Mbit/s
• Work underway to bring FTTH to
66 communities
• GPON with customer speeds up
to 1 Gbit/s
• Investment in GIS solution to
support current and future
requirements

Ireland’s National Broadband Plan
• Delivering a connected society
• State-led intervention for areas
where it is not commercial for the
market to invest
• EU State Aid clearance will be
required for the intervention
strategy once finalised
• Future proofed network with fibre
at its core is intended to
definitively address the urban
rural divide
• It is expected that the detailed
procurement process will take
place in 2015

Eircom - 4 Key Topics
1. Compare scenarios for FTTx?
2. Evaluate costs for FTTH across all areas
3. Create design for rural area (overhead / mix)
4. Create design for municipality (existing ducts / mix)

1. Compare scenarios for FTTx
– FTTH with varying sizes of Clusters
• Immediate view on impact on costs and filling
ratio of PON cards
• [Finished analysis on one community]
– FTTx
• Evaluate Fiber to the Street/VDSL/G.fast options
with varying max remaining copper distances
• [Not yet executed]

2. Evaluate FTTH costs across areas
– For all rural areas covering 760.000 premises:
• Accurate cost estimation for FTTH deployment per
sub area
• Ranking of sub areas / heatmap
– Including effect of sharing
feeder cable
• To allow identification of
ideal coverage for different
objectives
• [Ongoing]

3. Create design for rural area
– POC
• Rural area with typical ribbon
structure
– 158 buildings on 17km roads
• Reconstruction of manual design
• mostly overhead cables
• [Done]: very close to manual design
– New designs for 2 rural areas
• Area 1: 610 buildings on 40km roads
• Area 2: 120 buildings on 20km roads
• [Ongoing]

4. Create design for municipality
– Large urban area – 13.000
homes
• Initial Design by Comsof, then
finetuning within Standalone
Software by Eircom
– 2nd community
• Significant time savings on design
process

4. Create design for municipality
Automatically generated initial design
Finetuned by planner
Always view on total cost
Final design automatically pushed to Smallworld
Proof of
• Quality (matching numbers)
• Flexibility (easy scenario comparison)
• Efficiency (factor 2)
• Optimisation (increased PON port utilisation)Fixed Access Summit 2015 - Berlin
