Features
Casing feed-through type CFT with integrated fiber cable.- For bore hole Ø 10.7 mm
- Integrated Polarization-maintaining fiber cable
- Fiber type PMC-780
- Cable lengths 30/120 cm (inside / outside vacuum)
- Connector type FC APC (both ends)
Description
The fiber cable with casing feed-through made by Schäfter+Kirchhoff is equipped with a polarization-maintaining single-mode fiber cable for type PMC-780. The casing feed-throughs type CFT are installed by threading the outside part of the cable through an aperture from the inside of the casing.They are designed for casings with a Ø 10.7 mm through hole.
End-to-end fiber cable
The casing feed-throughs is supplied with a non-exchangable, continous, end-to-end fiber cable. That means there is no additional fiber connection (mating) at the vacuum flange.
Benefits:
- No additional coupling losses due to mating
- No reduction in Polarization Extinction Ratio (PER) due to mating
PM fiber cable
On the casing side, the fiber cable is equipped with Ø 900 μm buffer made of Hytrel. The part of the fiber cable outside the casing, has a Ø 3 mm cable with Kevlar strain-relief with bend protection both at the fiber connector and the flange.
