refers to a dark, Extra-Mural Absorption glass that is placed into
the fiber matrix to absorb stray photons not contained by the individual
fibers. This results in a significant reduction in fiber cross-talk.
EMA can be inserted into a fiberoptic array in several different
configurations, including statistical, interstitial, and circumferential.
In a statistical configuration, small rods of light-absorbing
glass are inserted into the matrix as replacements for individual
light-conducting fibers. Interstitial EMA is inserted into
the interstitial spaces between fibers, and circumferential
EMA is added as a complete jacket around each individual fiber.
The different configurations provide varying degrees of absorption,
proportional to the total volume and optical density of the EMA
