Fibre science for our fibres
Our fibre optics section covers many different types of conductors. All cables are based on two types of fibre. One is the gradient glass fibre. The other is the glass fibre in a gel-filled cavity. The glass fibres are divided into OM (optical multimode) classes. These classes differ in transmission rate, referred to as Gigabit Ethernet. Our cables are of class OM2 or OM3, depending on type. They are also available in various fibre diameters, comparable to the cross-sections of copper cables. Our fibre optics have 50/125µ and 62.5/125µ for multimode fibres and 9/125µ for single-mode fibres. Multimode means that the fibre can transmit multiple light spectra. The single-mode fibre transmits only one light beam.
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.
