These polarization-maintaining fiber optic patch cables are terminated on both ends with narrow key, ceramic-ferrule FC/APC connectors. NA is specified by the fiber manufacturer. Additionally the effective numerical NAe 2 is measured for each fiber batch by Schäfter+Kirchhoff. Available from stock, these cables feature a high-quality polish, which leads to a typical return loss of 60 dB. These fibers use internal stress elements that form two stable axes known as the fast axis and the slow axis, allowing the launched.
How do I attach a fiber cable?
To prevent damage to the sensitive fiber end-face, always insert the fiber connector's ferrule at an angle, with the connector key properly aligne...
What is the "right-hand orientation rule"?
When the ferrule tip is safely located in the inner cylinder of the receptacle, align the connector to the receptacle axis and carefully introduce...
Can I attach a narrow key fiber cable to a fiber coupler with a wide key receptacle?
Yes, you can- without any problem. Simply adhere to the "right-hand orientation rule". Generally, with any FC PC or FC APC type connector there is...
Can I use an end cap fiber with a mating sleeve?
Since the radiation has already started to diverge within the end cap, a simple mating is no longer possible. Please use a fiber-to-fiber coupler i...
Do you have a Ø 900 µm cable?
If yes, then the min. bend radius is 15 mm. More information can be found here .
Do you have a Ø 3 mm cable?
If yes, then the min. bend radius is 40 mm. More information can be found in the drawing here .
I look at my fiber end face and do not see a Panda structure? Why is that?
Chances are, that the fiber is equipped with end caps, that do not have a Panda structure themselves. The Panda structure within the actual fiber c...
Can I also couple into the fast axis of a PM fiber cable?
Conventionally the linearly polarized laser radiation is coupled into the slow axis because of its lower sensitivity to fiber bending. You can als...
