Attenuation in these objects can be measured using either the cut-back method or a technique known as OTDR, in which sudden spectral peaks indicate a splice loss. The performance of these devices is theoretically limited by the Rayleigh scattering limit, which is why exotic materials like fluoride are being developed for their manufacture. Depending on whether a discontinuity in the index of refraction is present between the core and the cladding, these devices are classified as step-index or gradient-index types. Like waveguides in general, variants of these devices which allow for more than one bound solution for each polarization are known as the multimode type. For 10 points, identify these optical waveguides which allow light to propag

For 10 points, identify these optical waveguides which allow light to propagate through a core, frequently made of glass, by means of total internal reflection.
