14.6.5 Fiber Color
Semi-opaque inks are commonly used to color-code and identify optical
fibers. These fiber colors are applied as thin coatings (several micrometers) on
top of the acrylate polymer coatings. The black color of a carbon coating can
affect the appearance of a color-coded fiber, causing the fiber to appear to be
darker. This may require that special color charts be used for hermetic fibers or
can require that certain colors be avoided to prevent misidentification.

When specifying the properties of a carbon-coated fiber, one must remember
that different ...
