Description

The main features of the fiber cable type PMC-1300-3-20V/18TV-xxx (also known as PMC-1300-9.3-NA012-3-OPC/APC.TI-xxx-P) include

Fiber
The fiber is a polarization-maintaning, single-mode Panda fiber, defined by its NA and its cut-off wavelength. The nominal NA is 0.12 and is specified by the fiber manufacturer. Additionally the effective numerical aperture NAe2 is measured for each fiber batch by Schäfter + Kirchhoff. The fiber has an effective numerical aperture NAe2 of 0.077 and a cut-off wavelength λco of 1300 nm. Maximum wavelength is 1625 nm. Besides the nominal cut-off wavelength λco, Schäfter + Kirchhoff also offers measured data for the cut-off wavelength for each individual fiber cable.

Fiber cable
The fiber cable has a 3 mm jacket in black with Kevlar strain-relief and a length of xx cm.

Fiber Connectors
The fiber cable is equipped with a fiber connector of type FC PC (0 deg polish, narrow key) at the one end and a fiber connector of type FC APC (8 deg polish, amagnetic, wide key) at the other end. All of the 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. The fiber cable is vaccum compatible down to 10-7 mbar.

Amagnetic fiber connectors
Amagnetic fiber connectors are completely made of titanium and have a ceramic ferrule. This ensures that the relative permeability µr of the connector is near 1 (χ = 5·10-5, µr = 1.00005), making it transparent to magnetic fields.
