Example8: tested, tested! Fibre optic cables – run 76.000 km Go 76.000 km or 1,5 times round the world with Chainflex® fibre optic cables. Users of data transmission systems (bus systems) with high data rates or long transmission lengths or even heavy EMC loads are relying on fibre optic cables more and more often. Many users today, however, are not conscious of the fact that the advantages that apply for fibre optic cables in general are even greater when Chainflex® fibre optic cables are used in E-Chains®. Data transmission systems on a copper basis usually have two basic disadvantages. 1. The maximum transmission lengths are greatly restricted by the transmission systems (between 5 and 50 m cable length depending on system and transmission frequency). 2. The copper-based cables used in moving energy supplies usually show an increase in attenuation values after some time at high cycle rates, which in turn have a negative effect on the maximum ranges. The case is completely different with data transmission or bus system-independent fibre optic cables made of glass. As well as being suitable for any transmission/bus system (providing the right converters are used), they have the follo - wing advantageous properties: 1. The transmission lengths are not restricted by the data transmission systems used and are – depending on the type of fibre optic cable used – several hundred metres long. 2. With Chainflex® fibre optic cables, the increases in attenuation even at very high cycle rates in E-Chains® are so low that the values are almost non-measurable, and most of the attenuation is to be found near the plug. The question of how greatly the attenuation behaviour of an igus® Chainflex® fibre optic cable changes has been examined using the following test set-up, which had not been concluded as the catalogue went to press (in 4/08).
