摘要	The optical continuity of a fiber optic conduit (14) is tested by terminating the fiber optic conduit (14) with an element having a wavelength-dependent coefficient of reflectivity, coupling (13) to the fiber optic conduit (14) light of a first wavelength band (36), detecting (48) light in the first wavelength band reflected back through the fiber optic conduit, coupling (13) to the fiber optic conduit (14) light of a second wavelength band (38), and detecting (48) light in the second wavelength band reflected back through the fiber optic conduit (14) and light in the second wavelength band reflected back through the fiber optic conduit (14). A relative comparison is formed of light in the first wavelength band reflected back through the fiber optic conduit (14). Reliable continuity testing of a fiber optic conduit (14) including multiple in-line connectors (15) is thereby made possible.
其他摘要	光纤导管（14）的光学连续性通过用具有波长相关的反射系数的元件终止光纤导管（14）来测试，耦合（13）到光纤导管（14）的第一光波长带（36），检测（48）第一波长带中的光通过光纤导管反射回来，耦合（13）到第二波长带（38）的光纤导管（14），并检测（48））第二波长带中的光通过光纤导管（14）反射回来，第二波长带中的光通过光纤导管（14）反射回来。通过光纤导管（14）反射回来的第一波长带中的光形成相对比较。由此使得包括多个直列式连接器（15）的光纤导管（14）的可靠连续性测试成为可能。
