    Abstract - (Show below) - (Hide below)

    Describes the background of encircled flux for the characterisation of multimode launch conditions.

    Scope - (Show below) - (Hide below)

    IEC/TR 61282-11:2012(E) is intended to show the background of encircled flux for the characterisation of multimode launch conditions. This includes the selection of the encircled flux and the definition of the encircled flux requirements in conjunction with the implied variation in attenuation measurements.
