In this article, we study the influence of external parameters such as magnetic field, temperature, and concentration of magnetic atoms, on the optical properties of a cylindrical quantum wire dilute magnetic semiconductor (DMS). We assume that the height of the cylindrical quantum wire is much greater than the radius of its base. The quantum system is also affected by a constant magnetic field directed parallel to the height of the cylinder. We define the type of confining potential as parabolic and inverse parabolic. Solving the one-electron Schrödinger equation within the framework of the effective mass approximation, we find the energy spectrum and the wave function of an electron. Further, considering these expressions, we arrive at a relation describing the absorption coefficient for interband optical transitions. From the expression for the absorption coefficient, it follows that interband optical transitions are performed under the condition m e = m h . Numerical results are presented Cd1-xMnxTe. According to the obtained results, it was found that the magnetic field, temperature, and concentration of magnetic atoms affect the maximum absorption coefficient for interband optical transitions. Namely, the increase in magnetic field as well as the concentration of Mn atoms shifts the maximum of the absorption coefficient to the blue side, and the increase in temperature shifts the maximum of the absorption coefficient to the red side.
