This paper presents the measurement of the dispersion spectrum of the gaseous Rubidium 85 at room temperature in the presence of electromagnetically induced transparency (EIT). We consider the system of the V-type configuration in which D2 line transition is simultaneously targeted by two counter-propagating laser fields - a strong coupling laser field and a weak probing laser field. Under the EIT effect, the anomalous dispersion in the resonant region is split into six “normal-anomalous” dispersion giving rise to six EIT-windows. Our experimental result suggested that the positions, as well as the slope of the curve at the dispersion domains, are controllable through both frequency and intensity of the coupling laser field. This insight is important for applications in high-resolution dispersion management
