Abstract
An optical fiber switch 9 comprises a group of optical fiber end faces 1, 2, 3, 4, 5, 6, including a first optical fiber end face 1 via which light is transmitted as an input signal and at least second and third optical end faces 2, 3 being the end faces of an optical loop 13. The group further includes a fourth fiber end face 4 via which light is transmitted as an output signal, and fifth and sixth fiber end faces 5, 6 being the end faces of an optical fiber loop 14. In a first position, light from the first fiber end face 1 is imaged into the second fiber end face 2 and is propagated through the fiber loop 13 to the third fiber end face 3 and imaged into the fourth fiber end face 4. In the second position, light from the first fiber end face 1 is imaged into the fifth fiber end face 5 and propagated through the fiber loop 14 through the sixth fiber end face 6 and imaged into the second fiber end face 2. Further, a fiber optic variable discrete delay system for electrical system includes one or more of the optical fiber switches 9 comprising a group of optical fiber end faces 1, 2, 3, 4, 5, 6 and means 8 for displacing the group of end faces 1, 2, 3, 4, 5, 6 relative to one another.
