FCC FibreCableConnect GmbH develops and manufactures fiber optic cables for laser beam delivery up to 1 kW laser power for industrial and medical applications, based on standarded connectors like SMA or D80. In addition, fiber bundles, probes for spectroscopy and optical fiber couplers as well as customer and application-specific special solutions.
For small fiber core Diameters with high power density dominate fiber connectors with a cylindrical end cap made of quartz glass currently. This end cap is larger than the fiber core and is spliced to the optical fiber. In doing so, the laser beam is focused onto the fiber core via the end surface of the quartz cap, where, at the same laser power, the power density is significantly lower.
This safety system monitors temperature and possible fiber breakage as well as connectivity. This can happen if the fiber was bent too tightly or torsedtoo much during the application or was mechanically damaged altogether.
The mode stripper is installed in the connector body and removes the cladding modes over a certain length. The required length is defined according to the coupling properties (spot size or NA difference). The mode stripper ensures that the beam profile at the fiber exit looks optimal. The stripped cladding modes are converted into heat in the connector body.
