Title: Multiple port, fiber optic isolator

Abstract: A multiport isolator provides optical isolation between pairs of optical fibers so that light may pass from a first fiber to a second fiber of the pair, but not from the second fiber to the first fiber. The multiport isolator has first and second coupling modules to couple light from different fibers, and an isolator module between the coupling modules to prevent light from passing from the second fiber to the first fiber of a fiber pair.
