WIRE AND CABLE MANAGEMENT
DECREASING
FIBRE
INSTALLATION
COSTS
S outh Africa is experiencing phenomenal
activity in the roll-out of fibre optic cables.
While no-one disputes that the installation
of fibre presents tremendous opportunities, the
question is, how will this demanding initiative af-
fect consumers’ Internet connection costs?
With speeds of up to 100Mbps, fibre will provide
unsurpassed Internet speeds. It is also reliable,
highly secure and able to withstand testing weather
conditions.“However, this large-scale, challenging
roll-out comes with a hefty price tag,” cautions
Bradley Hemphill, managing director of EES Live.
If the country is to replace its five million copper
cables with fibre optics,
according to figures recently released by
Finance24. “It is vital that fibre network installation
is carried out in themost efficient,yet cost-effective,
manner possible,” Hemphill continues.
It is important to select the most suitable optical
connection. It appears that previously, connector
technology usage was not based on the required
application but on the readiness and availability
of technology. Currently, access networks have
three technologies to choose from, namely fusion
splicing, mechanical splicing and factory pre-
terminated. Fusion splicing has been largely used
to date.
Requirements on which selection of connector
technology should be based are:
• Streamlined, easy, cost-effective installation
and maintenance
• Flexible connections in the network that can
easily be added to, joined or removed
• Ability to withstand harsh environmental
conditions
• Effective optical performance and secure
transmission of information
• Straightforward connectivity and fibre
organising system
When examining the three connector technologies
closely, it seems that the factory pre-terminated
technology option is the most suitable as it meets
all five requirements.
