TIA-455-47 Revision B, August 1, 1992 FOTP-47 Output Far-Field Radiation Pattern Measurement
More info
Description / Abstract: General
This procedure describes three methods by which the angular radiant intensity (far field) distribution from an optical fiber can be measured. Methods A and B are angular scans of the far field pattern; Method C is a scan of the spatial transform of the angular intensity pattern.
Numerical Aperture
This measurement method can be used to collect data that may be used in conjunction with FOTP-177 to determine the numerical aperture of graded-index multimode optical fibers.
Hazards
This method may employ laser sources and requires fiber alignment. Conform the design and operation of test equipment to the requirements of ANSI Z136.1 and/or Z136.2.
