英文摘要	A high resolution optical fiber length meter, live fiber detector, and reflectance tester (instrument) for single mode applications is disclosed. The instrument includes a low power, long wavelength laser 12 for generating wide and narrow optical pulses that are launched into a single mode fiber 40 under test. The laser output fiber pigtail is fusion spliced to a single mode coupler 16 whose output is coupled to the instrument bulkhead connector. A PIN photodiode 24 is fusion spliced to the single mode coupler to receive the reflected light from the fiber under test. The single mode coupler output has an optical delay 18 between the coupler and the bulkhead connector 20 to create separation between the laser pulse trigger switching noise and the first reflected pulse emanating from the bulkhead.; The high resolution hand-held instrument is useful in examining single mode passive optical networks (PON).
