The Importance of Trained Personnel in Fibre to the Home Delivery

The delivery of Triple play services over a solely optical network requires the

Planner, Installer and Commissioning Engineer to have a much deeper level

of technical understanding than was required when working with the

traditional copper infrastructure

The Importance of Trained Personnel in Fibre to the Home Delivery

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

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

Who Needs Training?

The Planner

The InstallerThe Installer

The Test and Commissioning Engineer

The fibre revolution brings greater bandwidth enabling enhanced services ,

to achieve this

Margins become ever tighter - OPEX can approach zero for passive plant

The Planner

Fibre selection is crucial – Especially within the MDU

Power Budgeting is critical, especially in PONs as the system will power will

drop over the lifespan due to component mishandling, damage and general

wear and tear increasing OPEX with callout and repair costs/system upgrades

Fibre standards must match the technology or extra losses will be introduced

during installation, such as bend sensitive fibre in MDU distribution

introducing macro-bending, again ramping up OPEX

The Planner – Influence on CAPEX and OPEX

introducing macro-bending, again ramping up OPEX

Topology chosen will affect the CAPEX, minimise plant for distribution,

maximise the use of all available deliver options – water, gas, sewage

Technology, choosing the right system can increase the range of services

available such as RFoG for DVB, Ethernet, Integration reduces outlay on

expensive hardware, avoids duplication and rationalises Network

Management

Always consider expansion and technology advances within the network

lifespan

We assume the Planner is an experienced engineer, but could come from a copper or

longhaul background so training in the following is essential to plan FTTH networks

to MDUs

How to Power Budget for PON and MDU

Standards and technologies for networks and services, feasibility of integration,

The Planner

Standards and technologies for networks and services, feasibility of integration,

Distribution Techniques for to the MDU and within including duct sharing

Fibre component selection to suit FTTH both external and within home/MDU

distribution, and what technology is around the corner

Most Installers come from a copper background, the

Techniques used in FTTH deployment need to be

much more precise

Quality installation essential –

The Installer

Bend Insensitive Fibre handled correctly

APC Connectors, Quality Tools

Rigorous adherence to standards – Awareness at all levels, i.e. if the wrong

Fibre or connectors are used this could greatly affect the budget and

increase OPEX

Accurate splicing and connector cleanliness right down to the point of

delivery.

Installation Techniques

Air Blown or Push Fibre can reduce initial installation CAPEX of MDU

distribution and provides cheap expansion/replacement of fibre

throughout network lifespan driving down OPEX, pre-terminated cabling

reduces timelines

The Installer

Installing in existing ducts, utility pipes, overhead requires unique

considerations but can provide large saving on CAPEX but risks the OPEX if

not done properly

Copper can be used in MDU from the ONU but should be treated as data

cabling rather than voice

Team Work is essential and where multiple disciplines are involved in a

fibre deployment the installer must be professional and work well with

the other operatives to a common purpose

Installation - Fibre Handling

Bends in the internal fibre cause losses –critical at the distant end of a PON

Connectors left dirty or badly fitted cause reflectance and losses

Dirty connectors can become damaged connectors – permanently

Call backs and fault rectification increase OPEX in an area where PONs should

represent savings over active networks they replace

The Installer

The Installer must –

Know the range of distribution techniques along the last mile as well as

within the MDU

Understand fibre care - losses incurred due to bends, dirty or damaged

connectors (Inspect, connect)

Adhere to safety considerations when working with Fibre Optics

Be aware of copper distribution methods for high speed networks usually

found in office environments

Testing and Commissioning

Testing must verify the budget and comply with the standards

Initial network testing should be thorough

The Network should be tested down to the most distant subscriberThe Network should be tested down to the most distant subscriber

Testing and Commissioning

Initial expenditure on qualified fibre test engineers can reduce OPEX by

identifying system losses and reflectance before activation

Rigorous checking of network connectivity, colour codes and labelling will

minimise management burden and OPEX on maintenance tasks and make

add-ons quicker and easier (and influence future FTTH projects)

Characterisation of PONs is especially difficult due to splitter loss

Once the Network goes live – testing requires PON Power Meters and out

of band OTDRs

Summary

The Planner, Installer and Test Engineer must know and work to the same

standards and same plan

There is a great deal of technical knowledge required to ensure benefits of

Fibre Optics are realised in terms of OPEX

Quality is key throughout the process, it is a quantum leap from copper last

mile to FTTH implementation
