Threaded Fiber Optic Feedthroughs

SQS threaded fiber optic feedthroughs in M10, M10 MINI, M12, and M16 versions provide reliable sealing for both vacuum and pressure applications. Their design ensures a fast and permanent seal in the chamber wall by means of a secure tightening nut, guaranteeing an immediate and long-lasting solution.

Each feedthrough is fully configurable, offering customizable housing lengths, high-quality O-rings, and the option to select from FC, ST, or SMA905 adapter interfaces. They are compatible with SM and MM optical fibers, including versions with polarization-maintaining fibers (PMF).

Additionally, our fiber optic feedthroughs feature a fully replaceable and removable connector interface with an inner mating sleeve, providing ease of maintenance and flexibility for upgrading your system.
