Fiber optic attenuator

摘要

An optical fiber attenuator (10) includes an optical fiber section (12a, 12b) having an end at an angle to the longitudinal axis (24) of the section. The end has on it a first layer (30) of substantially transparent anti-reflective material, a second layer (32) of light attenuating material on the first layer (30) and a third layer (34) of substantially transparent anti-reflective material over the second layer (32). A fourth layer (36) of substantially transparent, relatively hard scratch-resistant material may be added on the third layer (34).
