4 Introduction The principles of optical counications have been known for a long time but only in the last fifteen years have there been major applications in the field of telecounication, data and image transmission. This publication provides the main information required for good knowledge of optical core s and their most recurrent applications. Fibres The fibres include a central zone of silica with a high index of refraction called core, a pure silica layer with a lower index of refraction called cladding and a coating layer. The ray of light introduced in the fibre can be of different wave-lengths called mode and its number depends on the technology of the fibre production. The transmission principle of the light in an optical fibre is based on the total reflection between core and cladding. Continuous developments of the material quality which constitute the fibre have permitted better performances of the signal transmitted, reducing considerably the attenuation values and consequently the necessity of the amplification signal along the line. Meanwhile a better geometry of the core, cladding and coating supports the performance of joints and terminations, excluding nearly all attenuation increase. Design When we design a fibre optic, it is necessary to take in consideration the minimum bending radius appli, the frequency and the number of bendings, the thermal cycles and the pulling force to which the will be submitted during the installation. It s important therefore that all the design parameters and the production technology ensure that the fibres are free of any mechanical loads. The reliability of the fibre, as time passes, is largely due to the way that it has been placed inside the, which may be considered as a container of the fibre itself. The fibres must be longer with regards to the actual length of the itself to avoid or, in any case, to moderate the mechanical stress and pertinent to the thermal expansion to which the fibre will be submitted during the production and usage phases, assuring therefore a long period of life.

5 Special features very large transmission capacity very low transmission loss very low dispersion very long line without signal amplification needs iune to electromagnetic interference non crosstalk suitable for data, telecomunication video, etc. no radiation along the flame retardant low smoke and toxic gas metal free design rodent proof light weight small Safety performances In general all the s we produce can be supplied in flame retardant version and with low emission of toxic fumes and corrosive gasses. They can pass several test levels in accordance with national and international standards. These particular performances can be achieved using special materials for inner and outer sheaths and for other materials. Technical references Appropriate tests in accordance with the Quality Assurance procedures ensure a good performance. For all the material supplied to the customer, a technical documentation will be provided confirming the compliance of the product with relevant technical specifications proving the fulfilment of the constructional and performance characteristics.

BASIC TECHNOLOGIES Here below there are the three main technologies with which the fibre optic s are produced: Loose Tube, Slotted Core and Ribbon LOOSE TUBE The fibres are situated inside small s

Figure I shows a traditional stranded loose core. SLOTTED CORE The fibres are situated inside helical ducts of a central element (slot) together with jelly protection. The fibres must be free to move.

6 BASIC TECHNOLOGIES Here below there are the three main technologies with which the fibre optic s are produced: Loose Tube, Slotted Core and Ribbon LOOSE TUBE The fibres are situated inside small s together with jelly protection. The fibres must be free to move. The dimensions and the number of s can be different by way of the number of fibres they contain, the type of utilisation, etc. Figure I shows a traditional stranded loose core. SLOTTED CORE The fibres are situated inside helical ducts of a central element (slot) together with jelly protection. The fibres must be free to move. The dimensions and the number of ducts can be different by way of the number of fibres, the use, spare fibres for future utilisation. Figure shows a traditional slotted core. RIBBON The fibres are situated in the same layer, one near to the other and resinated with special materials: with this method we obtain the ribbon which overlaid on each other are fitted inside s or slotted-core. The number of fibres for each ribbon can be different (normally from up to fibres) and same for the number of ribbon for each or duct. Figure shows a traditional ribbon core.

OPGW OPTICAL PROTECTION GROUND WIRE The complete compatibility between the electrical power carrying and the optical transmission allows to optimise the use of low and medium tension network

28 OPGW OPTICAL PROTECTION GROUND WIRE The complete compatibility between the electrical power carrying and the optical transmission allows to optimise the use of low and medium tension network structures already existing or of new installation. The aperture of telecounication market to new telephone o p e ra t o r s, data transmission and video signals represent an addìtional possibility to employ OPGW everywhere. Its structure and its performances have been designed in relation with the characteristics of overhead lines where it will be installed. For example it has to be verified very carefully the short circuit current, which is very important for the calculation of the temperature which can develop in this case and the necessary cooling time. Some notes for the design of OPGW conductors are listed in the following pages. The OPGW conductor is usually composed of a central non metallic member containing the fibres, which is situated inside the steel or electro-welded. Over the are applied one or more layers of steel or aluminium, aluminium alloy and steel alloy wires. The type, the number and size of each wire is chosen an the basis of the working conditions. In some cases it is possible to use a non metallic optical fibre helically wound on the protection conductor or on the phase conductor. Some examples are shown in the following pages. What to take in consideration for the project Operating voltage of the power line Maximum short circuit current Short circuit time Supporting structure type OPGW installation system Pole span and conductor hang Range of temperature for storage, installation and operation Ground profile General weather condition Light frequency Maximum wind speed Maximum ice load
