In Step Index (SI) fibers, core and cladding feature fixed refractive indices with the index of the core always higher. This results in a step index profile.
A continuously decreasing refractive index enables high bandwidths and low pulse distortion, which is optimal for data transmission.
SM fibers with small core diameters are used in telecommunications for signal transmission across long distances.
Multicore fibers provide higher bandwidths with fewer cables and connections in data centers and switching stations.
The behavior of these fibers is modified by the introduction of certain materials and optimized for specific requirements.
These fibers are grown from a single crystal; therefore, they retain their material properties while remaining flexible.
Hollow quartz glass capillaries with a mirrored inside for the transmission of IR wavelengths are ideal for use in CO2 and Er:YAG lasers.
Robust bundles of two to six optical fibers for outdoor use: The cables can be equipped with all standard connector systems.
High birefringence spun fibers are used in polarimetric sensors, for example, to measure the Farraday effect.
