Multi-mode fiber cable with customer-specified fiber connectors.
The multi-mode fibers are either graded (gradient index, GRIN) index or step index fibers with an NA
specified by the fiber manufacturer. Schäfter+Kirchhoff offer pure silica core fibers with core diameter is 50 µm - 600 µm. There are fibers suitable for either the wavelength range UV/VIS or for the wavelength range VIS/NIR.
All fiber lengths can be customer specified. The multi-mode fiber cables
are offered with 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 narrow 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.
