Vacuum feed-through
The fiber cable with vacuum feed-through made by Schäfter+Kirchhoff is equipped with a single-mode fiber cable for type SMC-780. The feed-through is suitable for vacuums down to 10-7 mbar and is supplied with a small flange KF16 (DIN 28403 and ISO 2861, stainless steel).
End-to-end fiber cable
The vacuum feed-through 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.
The benefit is no additional coupling losses due to mating
SM fiber cable
On the vacuum side, the fiber cable is equipped with Ø 900 μm buffer made of Hytrel. The part of the fiber cable outside the vacuum, has a Ø 3 mm cable with Kevlar strain-relief with bend protection both at the fiber connector and the flange.
