ABSTRACT:
An optical simulator 10, shaped to be interchangeable with a complementary connector 7 that intermates with an optical connector housing 6 having an optical emitter 4 and an optical detector 5, comprises an alignment fixture 12 with connectors 21 and 22 for intermating with the optical emitter 4 and the optical detector 5, and an optical fiber 11 formed in a loop and installed within the alignment fixture 12 with a first end face 39 of the loop 11 aligned through a corresponding alignment fixture connector 24, with the emitter 4 and a second end face 37 of the loop 11 aligned through a corresponding alignment fixture 25, with the detector 5 of the optical connector 6. The optical fiber 11 further comprises an adjustable plunger mechanism 15 fitted through the body of the alignment fixture 12 to impose against the optical fiber 11 formed in a loop to thereby permit varying the degree of curvature of the loop by interjecting and retracting the plunger 15 against the loop.
