PbO contained multicomponent glass and fibers have been obtained by melting process and double crucible method. PbO containing glass is most promising for fabrication of high-numerical aperture optical fiber. In this study, main composition is $SiO_2$, PbO and glass composition mix component oxide such as $K_2O$, $Na_2O$, $B_2O_3$, $A1_2O_3$. Also, the optical, mechanical and structural properties of manufactured fibers by double crucible method are investigated.
