This paper presents a unsymmetrical wavelength multiplexing system on the basis of concrete conditions to improve the image quality and resolution of fiber optics telescope. Different combinations of prisms and lens are chosen as long as wavelength multiplexing systems have identical line dispersion. Accordingly, if the magnification of the original fiber optics telescope is (Gamma) , only two prisms with 1 : (Gamma) angle dispersion ratio placed before objective and after eyepiece respectively can meet the above demands. In the fiber optics telescope we designed, the system's magnification is 2.8X. The two prisms' angle dispersion are 18'30' and 52'18' respectively. The angle resolution of the telescope is 23', and it is improved by 70 percent compared with that of the original fiber optics telescope.
