  2. 2. The UK’s leading training provider with Government awards for training excellence State of the art facilities Unrivalled in the UK
  3. 3. The Importance of Trained Personnel in Fibre to the Home Delivery
  4. 4. The Importance of Trained Personnel in Fibre to the Home DeliveryThe delivery of Triple play services over a solely optical network requires thePlanner, Installer and Commissioning Engineer to have a much deeper levelof technical understanding than was required when working with thetraditional copper infrastructure The need for trained Installers and Technicians is universally accepted, However the following constraints must be considered Cost – Especially for Accredited and/or Practical Training Time – Training eats into project time lines Retention – It can be hard to hold on to trained staff Currency – Training has a lifespan
  5. 5. The Challenge To train a work force with the knowledge and practical skills needed to plan, install and maintain affective FTTH Networks To retain trained personnel whilst encouraging personal development Identify training needs to suit company portfolio
  6. 6. Types of Training Accredited Training Programs Bespoke Equipment Based Training Identify training needs to suit company portfolio and vision
  7. 7. Who Needs Training? The Planner The Installer The Test and Commissioning Engineer
  8. 8. The Planner The fibre revolution brings greater bandwidth enabling enhanced services , to achieve this Margins become ever tighter - OPEX can approach zero for passive plant Fibre selection is crucial – Especially within the MDU ONT ONT ONT 1310nm ITU-T G.652 ONTOLT WDM 1:8 ONT 1490nm ONT 1550nm ONT EDFA ONU -9.8dB Video
  9. 9. The Planner The Planner is key to the successful design and has a major affect on CAPEX and OPEX, the Planner’s roles include – System Design and Integration Component Specification Optical Power Budgeting ONT ONT ONT 1310nm ITU-T G.652 ONTOLT WDM 1:8 ONT 1490nm ONT 1550nm ONT EDFA ONU -9.8dB Video
  10. 10. The Planner – Influence on CAPEX and OPEXPower Budgeting is critical, especially in PONs as the system will power willdrop over the lifespan due to component mishandling, damage and generalwear and tear increasing OPEX with callout and repair costs/system upgradesFibre standards must match the technology or extra losses will be introducedduring installation, such as bend sensitive fibre in MDU distributionintroducing macro-bending, again ramping up OPEXTopology chosen will affect the CAPEX, minimise plant for distribution,maximise the use of all available deliver options – water, gas, sewageTechnology, choosing the right system can increase the range of servicesavailable such as RFoG for DVB, Ethernet, Integration reduces outlay onexpensive hardware, avoids duplication and rationalises NetworkManagementAlways consider expansion and technology advances within the networklifespan
  11. 11. The PlannerWe assume the Planner is an experienced engineer, but could come from a copper orlonghaul background so training in the following is essential to plan FTTH networksto MDUsHow to Power Budget for PON and MDUStandards and technologies for networks and services, feasibility of integration,Distribution Techniques for to the MDU and within including duct sharingFibre component selection to suit FTTH both external and within home/MDUdistribution, and what technology is around the corner
  12. 12. The InstallerMost Installers come from a copper background, theTechniques used in FTTH deployment need to bemuch more preciseQuality installation essential – Bend Insensitive Fibre handled correctly APC Connectors, Quality ToolsRigorous adherence to standards – Awareness at all levels, i.e. if the wrongFibre or connectors are used this could greatly affect the budget andincrease OPEXAccurate splicing and connector cleanliness right down to the point ofdelivery.
  13. 13. The InstallerInstallation TechniquesAir Blown or Push Fibre can reduce initial installation CAPEX of MDUdistribution and provides cheap expansion/replacement of fibrethroughout network lifespan driving down OPEX, pre-terminated cablingreduces timelinesInstalling in existing ducts, utility pipes, overhead requires uniqueconsiderations but can provide large saving on CAPEX but risks the OPEX ifnot done properlyCopper can be used in MDU from the ONU but should be treated as datacabling rather than voiceTeam Work is essential and where multiple disciplines are involved in afibre deployment the installer must be professional and work well withthe other operatives to a common purpose
  14. 14. Installation - Fibre HandlingBends in the internal fibre cause losses –critical at the distant end of a PONConnectors left dirty or badly fitted cause reflectance and lossesDirty connectors can become damaged connectors – permanentlyCall backs and fault rectification increase OPEX in an area where PONs shouldrepresent savings over active networks they replace
  15. 15. The InstallerThe Installer must –Know the range of distribution techniques along the last mile as well aswithin the MDUUnderstand fibre care - losses incurred due to bends, dirty or damagedconnectors (Inspect, connect)Adhere to safety considerations when working with Fibre OpticsBe aware of copper distribution methods for high speed networks usuallyfound in office environments
  16. 16. Testing and CommissioningTesting must verify the budget and comply with the standardsInitial network testing should be thoroughThe Network should be tested down to the most distant subscriber
  17. 17. Testing and CommissioningInitial expenditure on qualified fibre test engineers can reduce OPEX byidentifying system losses and reflectance before activationRigorous checking of network connectivity, colour codes and labelling willminimise management burden and OPEX on maintenance tasks and makeadd-ons quicker and easier (and influence future FTTH projects)Characterisation of PONs is especially difficult due to splitter lossOnce the Network goes live – testing requires PON Power Meters and outof band OTDRs
  18. 18. SummaryThe Planner, Installer and Test Engineer must know and work to the samestandards and same planThere is a great deal of technical knowledge required to ensure benefits ofFibre Optics are realised in terms of OPEXQuality is key throughout the process, it is a quantum leap from copper lastmile to FTTH implementation
