Abstract
A system for determining the condition of an optical signal includes a first refractive material having an interface with a second refractive material. The first refractive material receives an optical signal. A portion of the optical signal reflects off the interface between the first refractive material and the second refractive material as a reflection signal. A signal monitoring circuit determines the condition of the optical signal using the reflection of the optical signal at the interface between the first refractive material and the second refractive material.
