V-KF16-PMC-780-18-30/120

Vacuum feed-through

V-KF16

Features

Vacuum flange type KF16 with integrated fiber cable.

Based on small flange KF16 (stainless steel)
Suitable for vacuums down to 10^-7 mbar
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 vacuum feed-through made by Schäfter+Kirchhoff is equipped with a polarization-maintaining single-mode fiber cable of type PMC-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.

Benefits:

No additional coupling losses due to mating
No reduction in Polarization Extinction Ratio (PER) due to mating

PM 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.
