Fiber Optics Feedthroughs

Standard Single Mode Fibers

Optical Fiber feedthroughs with integrated singlemode fibers are made for a finite specified wavelength.

When singlemode fibers are used to transmit laser power the use of FC/APC connections is recommended. With FC/APC connectors reflections at the coupling interfaces are refracted into the fiber cladding, optimizing the signal to noise ratio. Our optical fiber feedthroughs are Ultra High Vacuum compatible and offer low insertion loss, resulting in very high transmission.

Standard Multi Mode Fibers

Optical Fiber feedthroughs with integrated multimode fibers are made for a broad wavelength range. Fibers with core diameters of 50 μm, 200 μm, 400 μm and 600 μm are offered. These feedthroughs cover many applications in the ultraviolet range (UV), in the visual range (VIS), and in the near infrared range (NIR). Fibers with a core diameter of 200 μm - 600 μm provide a refractive index with step-index distribution. The MM50 fiber is a graded index fiber which shows minimal mode dispersion due to an optimized refractive index.

FC/APC Connection

Threaded FC/APC connectors (typically used with Single Mode fibers) are designed for high-vibration environments and minimal back reflections. The "APC" stands for "angled physical contact" these connectors allow the surfaces of two connected fibers to be in direct contact with each other. The fiber is polished at an angle to prevent reflected light from traveling back up the fiber.

FC/PC Connection

Threaded FC/PC connectors (typically used with Single Mode fibers) are designed for high-vibration environments. The "PC" stands for "physical contact" because these connectors allow the surfaces of two connected fibers to be in direct contact with each other.

SMA Connection

SMA connectors, which are most commonly used with multimode fibers, have a ferrule design that is ideally suited for large core fibers.
