Design of hermetic fiber optic feedthroughs
KTRAV-M12V fiber-optic hermetic feedthroughs are suitable for vacuum and cryogenic applications. They provide a high level of hermeticity of the order of 10-8 to 10-9 mbar.l/s.

KeyFeatures
- 10-8 to 10-9 mbars.l/s hermeticity,
- PM, SM or MM fibers,
- FC/APC, FC/PC connectors,
- Single-channel,
- M12 thread,
- UV-VIS-NIR wavelength ranges.
The KTRAV-M12V hermetic fiber-optic feedthrough is a compact single-channel feedthrough in M12-thread screw-in FC adapter interface.
It is suitable for high vacuum applications and for cryogenic environments. It ensures a high level of hermeticity in the order of 10-8 to 10-9 mbar.l/s.
It accepts polarization maintaining fibers, singlemode fibers, multimode graded-index fibers, as well as multimode step-index fibers with a cladding diameter of 125 μm.
The M12V version exists with either FC/APC or FC/PC connectors.
The KTRAV-M12V is a solution suitable for a panel thickness of 1 to 9.5 mm with a hole diameter of 12 mm.
