Features

Casing feed-through type CFT with integrated fiber cable
  • For bore hole Ø 10.7 mm
  • Integrated polarization-maintaining fiber cable PMC
  • Fiber cables with cut-off wavelengths 360 nm - 1800 nm
  • Different connector types

Description

The fiber cables with casing feed-through made by Schäfter+Kirchhoff are equipped with polarization-maintaining single-mode fiber cables for wavelengths from 360 to 1800 nm. The casing feed-throughs type CFT are installed by threading the outer part of the fiber cable from the inside of the casing through the through hole.They are designed for casings with a Ø 10.7 mm through hole.

End-to-end fiber cable
All casing feed-throughs are supplied with a non-exchangable, continous, end-to-end fiber cable. That means there is no additional fiber connection (mating) at flange.

Benefits:

PM fiber cable
Inside the casing, the fiber cables are equipped with Ø 900 μm buffer made of Hytrel or Nylon. 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.
The polarization-maintaining fiber cables can be equipped with end caps for reducing the power density at the fiber end-faces.
As an option the connector can be made of amagnetic Titanium (connector type FC only).

Please refer to the individual PMC fiber cable pages for all fiber options. The connector types are described in detail here

How to order
For a specific feed-through please contact Schäfter+Kirchhoff. We additionally need information on:

  • Fiber type
  • Cable length inside / outside the casing
  • Connector type inside / outside the casing

An example configuration can be found here.
