1. an assay method for large core fiber Transmission loss, is characterized in that described assay method step is as follows:

  • One, preparing a length is 100m ~ 1000m large core fiber standard wire jumper;

    Two, wire jumper two ends are accessed common communication fibre optic multimeter source ends and light power meter end respectively, first the output power of 100m ~ 1000m optical fiber is measured, when keeping injection condition constant, output power is measured, using this output power as power input at the position from injection side being 2m;

    Three, output power step 2 measured and power input bring loss A (λ

    ) and the Transmission loss α



    ) that following update equation obtains optical fiber into;
