Chainflex cables

Example 8: tested, tested!Fibre optic cables –run 76.000 kmGo 76.000 km or 1,5 times round the worldwith Chainflex ® fibre optic cables.Users of data transmission systems (bus systems) with highdata rates or long transmission lengths or even heavy EMCloads are relying on fibre optic cables more and more often.Many users today, however, are not conscious of the factthat the advantages that apply for fibre optic cables in generalare even greater when Chainflex ® fibre optic cables are usedin E-Chains ® .Data transmission systems on a copper basis usually havetwo basic disadvantages.1. The maximum transmission lengths are greatly restrictedby the transmission systems (between 5 and 50 m cablelength depending on system and transmission frequency).2. The copper-based cables used in moving energy suppliesusually show an increase in attenuation values after sometime at high cycle rates, which in turn have a negativeeffect on the maximum ranges.The case is completely different with data transmission orbus 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 datatransmission systems used and are – depending on thetype of fibre optic cable used – several hundred metreslong.2. With Chainflex ® fibre optic cables, the increases in attenuationeven at very high cycle rates in E-Chains ® are so lowthat the values are almost non-measurable, and most ofthe attenuation is to be found near the plug.The question of how greatly the attenuation behaviour of anigus ® Chainflex ® fibre optic cable changes has been examinedusing the following test set-up, which had not been concludedas the catalogue went to press (in 4/08).Product informationCFLG.2H page 158
