Patent ID: 8593621

Claim:
A system for testing whether an optical fiber is properly connected to a device, comprising: a first laser source operable to output a first beam of light having a first wavelength to the optical fiber; a second laser source operable to output a second beam of light having a second wavelength different than the first wavelength to the optical fiber; and a detector operable to: detect a first intensity of light reflected by the device back through the optical fiber in response to the first beam of light; detect a second intensity of light reflected by the device back through the optical fiber in response to the second beam of light; and determine, in response to the detected first and second intensities, whether the optical fiber is properly connected to the device, and wherein the detector is operable to determine whether the optical fiber is properly connected to the device at a connector, wherein the connector includes a component functioning as a wavelength-specific reflector for reflecting the first beam of light and absorbing the second beam of light when the optical fiber is properly connected to the device.
