Global Internet UseageGlobal Internet Traffic

Africa's place in data consumption

Rest of the World (excluding Africa) as at 31st December 2013

Estimated World Population is 6billion people

Internet users stand at 2.6 billion people (43%)

Growth of 719% from the year 2000

Continent of Africa as at 31st December 2013

1.1billion people inhabit the continent of Africa

But Internet users stand at only 240million people (21%)

However, a growth of 5320% from the year 2000

The Pros & Cons of Buried Fiber

Good points…

More suited for urban environment with high population

Extensive network design options to suit deployment strategies

Mature & extensive supplier list with common themed products

Traditional installation methods known & understood

Not so Good points…

Access to open the roads and bury ducts not always an option

High cost and time of trenching

Theft of cables once deployed and left is a headache

No guarantee of customers once access distribution in place

Very expensive & generally a high level of competence to deploy

Very high cost for re-instatement and/or replacement

Competing against an incumbent who has infrastructure

Aerial pre-survey considerations

Pre Survey of the intended location/area

In the same manner as cable in duct, determine the best route

Network planners vital to success of designing the most efficient route

Local authority access consideration still a major key

Characteristics of trees or other obstructions need to be investigated

Potentially advise from the NESE (National Electric Safety Code)

Proximity to existing fiber backbone network

Aerial infrastructure considerations

Existing Infrastructure

Consideration for existing pole infrastructure or requirement for new poles

Authority or Utility owned infrastructure

Can the existing infrastructure support an ADSS solution

Is the span sufficient to support an ADSS solution

Will the poles have the FTTH reach required by the planners

If not, can your own poles be deployed

M2fx aerial installation in Hungry Planning for the future ..?

Aerial infrastructure considerations

Pole mount requirements

Two Dead-end supports required at each pole to carry the cable

Or

One Tangent supports required for longer and heavier cable runs

NESC compliance is essential for ensuring suitable span lengths

Corrosive resistant materials for 25+ year outdoor performance

No tooling, easy to install & minimal training to further deskill the installation

Dead-End Support Tangent Support

Aerial installation methodology

Stationary Pay-Off Installation Method

Generally used above existing lateral cables or other obstructions

A series of Tangent blocks are first installed on each post

A pull line is threaded in each of the tangent blocks and tied to the cable

A tension-limiting winch is used to pull the cable into position

Cable sag/slack implemented before building access/splicing can begin

ADSS cable

Aerial installation methodology

Driving Off/Moving reel Installation Method

Used when the path is deemed obstruction free and one pass install

No need for the tangent blocks as cable deployed ‘on-the-fly’

Aerial installation considerations

ADSS Installation Strand storage options

Changes in deployment techniques

Vastly increasing efficiency as aerial removes the need for trenching

Generally Green field deployment speeds time to market

Direct access to the poles removes any constraints and waiting time

Lower cost installation accessories increases the ROI for aerial

Limited/zero installer training for mounting pole accessories

Connect customers immediately as you light up an area

Aerial cable considerations

Cable selection is essential for successful deployment

Combined cable for Distribution and Drop requirements

MDPE material gives excellent UV stability and 25+year UV resistance

Temperature range from -40°C/+80 °C for the African environment

6mm supports up to 24-Core loose tube fiber design weighing just 23kg/km

7mm supports 36 and 48-Core bundles weighing just 35kg/km

Maximum fiber protection with Crush >2,000N and Tensile >1,000N

Unrivalled flexibility of 5X bend radius with span >68m

With the addition of Water Blocking Yarn, can also be used for direct bury

Not all aerial cable is created equal

Ultra light cable is unsung star of Cornwall fibre roll-out

The ‘Big Build’ as it’s known – a partnership between the European Union,

BT and Cornwall Council to roll-out high speed broadband to the county and

the Isles of Scilly – signed up its 10,000th customer

Chris Munnings : BT Innovate & Design’s Access Platform team

“If engineers were to use traditional aerial fibre cable, it would require a

survey, planning & remedial work before they could be installed.

Not only would this take a lot of time, it would also be expensive.

The (m2fx) cable is strung on existing telegraph poles, but because it is so

lightweight, the poles and other fittings do not need to be strengthened.

Put simply, many parts of rural Cornwall wouldn’t be able to get cost-

effective fibre broadband without this cable,”

Aerial Fiber Distribution Points

Moving the FDP from the ground to the pole

Removes the need for site rental for Ground Nodes

Eliminates the need for Man-Holes every 250-300m

Pole mounted FD nodes ranging from 4 to 288 splice connections

Preterminated to remove the need for additional field splicing

Lightweight and easy to handle

Reduces the visible footprint and in turn, reduces the Opex on the network

Extending fiber penetration beyond the urban environment

Vastly reduces the homes past v household connections ratio

Removes the need for extensive and time consuming trenching

Removes the need for air blown fiber

Reduces the installer skills requirement

Increased time to market and ROI

Cons

Possible restriction due to existing pole infrastructure

Requirement to re-train installers and new equipment
