Several different designs are used to create birefringence in a fiber. The fiber may be geometrically asymmetric or have a refractive index profile which is asymmetric such as the design using an elliptical as shown in the diagram. Alternatively, permanently induced in the fiber will produce ; this may be accomplished using rods of another material included within the cladding. Several dif.
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...
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...
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...
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...
