Claims
- 1. An optical simulator shaped to be interchangeable with a complimentary connector that intermates with an optical connector having an optical emitter and an optical detector, the optical simulator comprising an alignment fixture with connectors for intermating with the optical emitter and the optical detector, and an optical fiber formed in a loop and installed within the alignment fixture with a first end face of the loop aligned with the emitter, and a second end face of the loop aligned with the detector of the optical connector, said simulator further including attenuation inducing means, wherein:
- the optical simulator comprises a solid molded body of an electrically insulating material and;
- the optical fiber formed in a loop comprises an optical fiber having a relatively rigid coating of uniform thickness comprising an inner relatively thin electrolessly plated metal coating and an outer and relatively thick coating of electroplated metal of uniform thickness.
- 2. The optical simulator of claim 1 wherein the said attenuation inducing means includes modification of an end face of the fiber by application of an optically thin film to provide attenuation of the optical power to the optical detector.
- 3. The optical simulator of claim 1 wherein the said attenuation inducing means is a core diameter mismatch or numerical aperture mismatch between the end face of the fiber and the detector.
- 4. The optical simulator of claim 1 wherein the said attenuation inducing means includes an optical filter attached to an end face of the fiber to provide attenuation of optical power to the optical detector.
- 5. The optical simulator of claim 1 wherein the fiber core is coated with metal to an outer diameter of 500 microns.
- 6. The optical simulator of claim 1 wherein the optical connector is the adapter assembly of a transceiver.
- 7. The optical simulator of claim 1 wherein the simulator is a plug-compatible shape for disconnect coupling to the optical connector to a transceiver.
- 8. The optical simulator of claim 1 wherein the electronically insulating material is selected from the group consisting of ceramics, thermoset polymers and high temperature thermoplastic materials.
- 9. The optical simulator of claim 8 wherein the thermoplastic materials are selected from a group consisting of polysulfone, polyetherimide, polyethersulfone, polyphenylene sulfide, and polyetheretherketone.
