摘要：
The optical continuity of a fiber optic conduit is tested by terminating the fiber optic conduit with an element having a wavelength-dependent coefficient of reflectivity, coupling to the fiber optic conduit light of a first wavelength band, detecting light in the first wavelength band reflected back through the fiber optic conduit, coupling to the fiber optic conduit light of a second wavelength band, and detecting light in the second wavelength band reflected back through the fiber optic conduit. A relative comparison is formed of light in the first wavelength band reflected back through the fiber optic conduit and light in the second wavelength band reflected back through the fiber optic conduit. Reliable continuity testing of a fiber optic conduit including multiple in-line connectors is thereby made possible.
