Reflectivity tests
WebRetroreflection occurs when a surface returns a large portion of directed light beam back to its source. Retroreflective materials appear brightest to observers nearest the light source (such as a motorist). The object’s brightness depends on the intensity of the light striking the object and the materials the object is made of.

WebReflectivity tests and pyramid height measurements were used to study the efficiency of the texturing processes. In a related study [2] it was found that 20µm of material removal was required to attain minimum surface reflectivity. Further removal of material affected pyramid dimensions, but did not improve surface reflectivity. Webreflective feature on an OTDR trace appears larger when measured by shorter pulse widths and therefore are often misinterpreted as a cause for concern during cabling or …
