  • Abstract
    The authors propose an improved near-field scanning system for measuring the mode distribution exiting a multimode fibre (MMF), notably for evaluating conformity to the encircled flux (EF) standard of a measurement source used for MMF loss/attenuation characterisation. This system offers advantages over both charge coupled device (CCD)-based and traditional scanning approaches. EF measurements taken with this new system are in excellent agreement with CCD-based measurements.
