Abstract: A system for detecting a location of optical energy leakage from optical fibers, including a portable imaging device for generating a visible image of one or more optical fibers within a field of view of the portable imaging device, an optical energy detector assembly associated with the portable imaging device and configured to detect a location of optical energy leakage from an optical fiber within the field of view of the portable imaging device, and a processor associated with the imaging device and the optical energy detector assembly for overlaying a computer generated representation of the detected location of optical energy leakage from an optical fiber within the field of view of the portable imaging device over a visible image of the plurality of optical fibers generated by the portable imaging device to create a composite image.

Abstract: A self-contained calibration method for improving stability of an optical source in an optical network test instrument includes performing a temperature sweep test of the optical source. Optical output power of the optical source is periodically measured. A temperature correcting value is generated based on the measured optical output power. The optical output power of the optical source is adjusted by applying the temperature correcting value to obtain a substantially constant optical output power of the optical source.

Abstract: A test instrument comprises plural first optical signal sources at a first wavelength and a distributor coupled to the plural first optical signal sources to supply the signals produced to a multi-fiber test port. Additional second wavelength signal sources may be provided, and a second test instrument for use at a second end of the link under test may be provided, to effect testing of the optical link.
