Characteristics of some alternative fibers

Although the Madge Smart 16/4 Fiber Ringnodes are optimized for use with 62.5/125um fiber, you can use other fibers.

The characteristics of some alternative fibers are:

Alternative fibers

Core diameter
Cladding diameter 50um
125um 85um
125um 100um
140um

Nomimal numerical aperture 0.20 0.26 0.29

Core/cladding concentricity error <=6% <=6% <=6%

Core non-circulatory <=6% <=6% <=6%

Cladding non-circulatory <=2% <=2% <=2%

If you are using alternative fibers, you will need to check that the Optical Power Budget and Modal Bandwidth are suitable.
