Polarization-maintaining, endlessly single-mode, photonic crystal fiber cables series PCF-P-5 with Gaussian intensity profile and low-stress fiber connectors with end caps.
Fiber
The fiber is a polarization-maintaining, endlessly single-mode PCF fiber, categorized by its core diameter (in this case 5 µm). The mode-field diameter MFD is almost independent of wavelength.The effective numerical NAe2 is wavelength dependent and is measured for each connectorized fiber and various wavelenghts by Schäfter+Kirchhoff. The special broadband fiber has an operational wavelength range of 370 nm to1550 nm.
Fiber Cable
The fiber length can be customer-specified (there is a minimum fiber length). The polarization-maintaining PCF 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 connector type can be chosen (FC PC with 0°-polish or FC APC with 8°-polish). The fiber connectors of type FC assembled by Schäfter+Kirchhoff have an alignment index (key), wide key (standard).
End Caps
The fiber connectors of all PCF fiber cables are equipped with an end cap. This means that a short piece of coreless fiber (< 300 µm) is spliced onto the polarization-maintaining PCF fiber. The end cap seals the microstructre of the fiber and allows for an easy cleaning of the end-face. Additionally it also reduced the power density at the fiber end-face.
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.
