Description

The main features of the fiber cable type PMC-1550-3-60/20T-xxx (also known as PMC-1550-10.1-NA012-3-E2000/OPC.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 0.125 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 0.092 and a cut-off wavelength λco of 1550 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 E2000 PC (0 deg polish) at the one end and a fiber connector of type FC PC (0 deg polish, amagnetic, narrow key) at the other end. All of the fiber connectors of type FC assembled by Schäfter + Kirchhoff have an alignment index (key). The narrow key (type "R") fiber connector has an alignment index (key) of 2 mm width.

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.
