Abstract
An FDDI loopback connector or optical network is suitable for testing in fiber-to-fiber applications and designed to be interchangeable with a complimentary connector. The loopback tester is afforded a desired level of attenuation by providing a fiber loop having a controlled air gap. Adjustment of the air gap will afford a desired attenuation level.
