Step index multimode fiber was the first fiber design. The core of step index multimode fiber is made completely of one type of optical material and the cladding is another type with different optical characteristics. It has higher attenuation and is too slow for many uses, due to the dispersion caused by the different path lengths of the various modes traveling in the core. Step index fiber is not widely used - only POF and PCS/HCS (plastic or hard clad silica, plastic cladding on a glass core) use a step index design today. POF is mainly used for consumer audio and TV links.

Optical fiber attenuation is sensitive to stress like encountered when bending fiber too tightly, especially with patchcords and fibers in tight enclosures. Stress causes light to exit the core of the fiber causing loss. A modification to the fiber index profile, adding a low index layer of glass around the core, usually called an optical trench, that guides or reflects light lost from the core back into the core can make fiber much less sensitive to bending losses. This can be done with both multimode and singlemode fibers.
