An attenuator for fiber optic cable has a device for receiving a length of the cable. A series of attenuation structures is defined on the device, the attenuation structures being located proximate to each other. Each of the attenuation structures is adapted to bend the cable through a corresponding arc to alter the path of the fiber optic cable so that a signal traveling through the fiber optic cable is attenuated. Additionally, the attenuation structures are individually accessible to select a desired amount of attenuation.
