The
graphs above show the transmission characteristics for fiber
optic bundles and single fiber cables. The curves for the
bundles have included in the transmission the losses due to
packing factor, reflections at the entrance and exit, and the
losses within the fiber itself. Please contact us if you need a
more detailed explanation or to discuss your requirements.

Optical Fiber Bend Radius
Below is a table of the bend radius for a single fiber of the
core sizes listed. Fiber bundle and cable bend radius may be
further limited by sheath material, fiber quantity, and length.

Optical Fiber
Acceptance Angle
The acceptance angle of an optical fiber
is dependent upon the refractive indices of its core and
cladding materials. The table below shows the acceptance angle
