A novel seven-core multicore tellurite fiber is proposed and fabricated in the paper. Each core with high index is made of 70TeO(2) - 8Li(2)O - 19WO(3) - 1MoO(3) - 2Nb(2)O(5) (mol%) glass. The background with low index is made of 70TeO(2) - 20ZnO - 5Na(2)O - 5La(2)O(3) (mol%) glass. Compared with the single- core tellurite fiber, this fiber has novel chromatic dispersion with two zero- dispersion wavelengths at 1.86 mu m and 2.16 mu m. The spatial interference fringes generated in the different cores of the fiber are obvious.
