The use of underground fibre optics networks has now spread to several sectors including utilities, CATV, telephone and internet networks. All the underground fibre optics installations require specialized equipment that can do the job on a large scale as required. http://www.cablelaying.com.au

1. The Various Uses of Underground Fibre Optic Networks
The use of fibre optics has spread to several sectors including cell phone, telephone and
internet networks. Underground fibre optic networks are also now being used for CATV and
utilities installation. The telephone, cell phone and internet providers make use of a lot of fibre
optic cables most of which have to run underground. These cables can be buried directly
underground, submerged under water or pulled through conduits. They have several point-to-
point links connecting phone switches and can go very long distances.
Underground fibre optics networks for CATV use a lot of single mode fibre optics in the
backbone of the networks. They use an overbuild architecture which bypasses coax that has
already been installed to connect local nodes that serve few subscribers in order to give high
quality signals. The fibre optics is a much more reliable alternative to copper wires that were
initially used for CATV. Most CATV systems now use the underground fibre optics to carry their
signals to the customers.
Most cities, municipalities and other urban settings are also turning to underground fibre optics
networks. They are even adding CCTV surveillance cameras and traffic controls during the
underground installation process. There are some local council authorities that even offer high
speed connections on their own fibre optics networks to any interested local businesses or
residential homes. The networks mostly use single mode fibre, and the underground fibre optics
installation can be done in existing conduits.
Utilities usually require underground fibre optics networks since they use a lot of fibre optic
cables and CLP is able to provide the equipment for this. Most of the modern high voltage
distribution lines carry fibre optics in the centre of the ground wire (OPGW-Optical Power
Ground Wire). The fibre optics is used for local grid management systems and also helps in
communications. High voltages or any types of electrical noises never interfere with fibre optics
cable transmission that is why the utilities companies also use fibre optics cable in their
substations for control signals. Fibre optics links for utilities generally use multimode fibre, and
in some cases even step-index PCS fibres for their low-speed signals.
The underground installation of fibre optics cable requires a wide range of materials and
specialized equipment. Some of these equipments include hydraulic power packs, screw-on
hauling eyes, cable feeders, cable jets and various types of winches. Most of these underground
fibre optics installations are usually huge projects that require the equipment to be supplied by
a competent company with the capacity for such undertakings.
