Nested optical fiber MZI is an essential part for achieving hiegh data rate network system.In Lne Double Cladding Multimode Nested Mach-Zehnder(DC MMF-NMZI)was designed for rapid pregnancy test using urine as abilogical material .Three different cladding of MMF were inpelemented to constract nested MZI has capability to distinguish between many subscriber signals (sensing signals).Compression factor was figure of merite of this wor; that indicate also to the maximum excitation to hiegher order modes in the cladding region in other words obtained maximum ratio of power to power core , FC=1.1 At fiber diameter is 112.392μm, and maximum peak power is 3.49μW at central wavelength was 1564.9nm and number of excitation to the hiegher order modes is 10874 also RIU/nm was obtained.
