4site’s fiber journey….. Completed first FTTN designs 10 years ago 2006 to 2013, engaged in low run rate FTTN rollouts - planning, design and
certification Commissioned comprehensive FTTX market analysis in 2013 Developed expansion strategy and integrated fiber services into core business
operations Created dedicated fiber solutions department Invested in people, tools and ongoing development cycles Rapidly expanded capacity and competency between 2014 and present to
service FTT(H)(B)(C)(A) projects and opportunities Constantly exploring new tools and ways of working to improve design process
and deliver greater program & cost certainty
Our fibre services…save time, control costs1. Optimised FTTx design
Network survey, data validation and design service Flexible design Speed of delivery Quick time to revenue using
– Proven methodology– Expert fibre planners– Powerful software tools – FiberPlanIT Designer & Simulator
2. Independent FTTx verification and optimisationProve validity of existing designs and improve where
possible Deliver on metrics Budget focussed Iterative review and consolidated deployment approach
– Managed program– Change receptive– Independent– Client tailored solution
The challenges….. Defining most appropriate network architecture Accuracy of GIS input data Managing an evolving end to end solution

The Challenge The Solution The ResultReduce time taken to complete designsIncrease accuracy of costingsReduce time taken to complete BOM and develop cost model
4site conducted full process reviewReimagined the design processIntroduced new design toolsAutomated a number of time consuming tasks
Speed: Reduction in design timeAccuracy & Managed Risk: BOMs automatically linked to model spaceBudget Management & Margin:Improved Cost Accuracy
Case Study: National Urban FTTB deployment
The Challenge The Solution The ResultProof of Concept (POC) for a rural fibre deployment. 4site’s Fibre Design Model to be tested against client’s approach
4site fibre design tools and methodology applied to: Rural cluster Underground feeder from POPOverhead distribution
4site model proven and delivered real advantages; Reduction in network design
time Reduction in deployment costs Multiple design iterations
without extensive cost and resource
Optimised design rule benefits Accurate costs produced +/-

Key lessons learned to date………. No one size fits all approach• Integration with existing client processes and tools• Incorporate new components and architectures• Optimised tools to speed up the process - FiberPlanIT Designer & Simulator
Developed multi-layered delivery teams• Experience & competency mixes• Fiber, Tx, Civils, ROW, GIS, PM• Wisdom and tech wizardry
Input data quality• Critical to verify accuracy of any existing GIS records• Optimally time & scope field survey to verify data, support design & pre-start build
