Multi-mode fiber cable with customer-specified fiber connectors.
The multi-mode fibers are either gradient index or step index fibers with an NA
specified by the fiber manufacturer. The core diameter is 50 µm - 300 µm. Fibers can be either be used in the wavelength range UV/VIS or VIS/NIR.
All fiber lengths can be customer specified. The multi-mode fiber cables
are offered as Ø 900 µm buffer in black, or a Ø 3 mm cable in black with Kevlar strain-relief.Fiber Connectors
For each fiber end the fiber connectors can be selected from a wide range of connector types
(FC, DIN or AVIO, E2000, ST (only 0°-polish), or F-SMA (only 0°-polish) with 0°-polish or 8°-polish. All fiber connectors of type FC assembled by Schäfter+Kirchhoff have an alignment index (key). The wide key (type "N") fiber connector has an alignment index (key) of 2.14 mm width. The narrowe key (type "R") fiber connector has an alignment index (key) of 2 mm width. Special fiber connectors are available so that the fiber cable is vaccum compatible down to 10-7
mbar (only Ø 900 µm buffer fiber cables). Amagnetic fiber connectors
For FC PC or FC APC type connectors amagnetic versions
completely made of titanium can be selected. Those connectors have a ceramic ferrule. The relative permeability µr
of the connector is near 1 (χ = 5·10- 5
= 1.00005), making it transparent to magnetic fields.
