Why the fibre optic cable is the bus line for long distances etc.
Can glass move? Yes, it can – it can move very well. If it is designed correctly. Four reasons for a fibre optic cable in the e-chain. First, there is data volume. Compared to the common field buses used in automation technology, this is almost unlimited for a fibre optic cable. As a rule, two fibres are used, one for the outward and one for the return journey. Interference from other electrical sources can also be ruled out since no signal couples into the optical fibre. Glass is also suitable for long travels. Bus systems based on copper quickly reach their limits beyond 50m. A fibre optic cable can be used beyond 1000m. What is particularly surprising is the extremely small radius that our cables can achieve. With conventional bus systems that use copper, such as Profinet, all of these points can lead to transmission problems and subsequently to cable failure.
