Multimode fiber is the frequent choice. Slower than singlemode, but much more cost effective on both the equipment and cable side. Multimode is also more than sufficient for LAN traffic.

Multimode Fiber. This is because its core diameter is larger than single mode fiber, therefore permiting photonic pulses (light rays) to travel in multiple paths, which correspond to different modes, within the fiber. Each of these multiple paths has a slightly different length, depending upon how often the light bounces off the reflective boundary of the core. Once emitted, individual photons within the same pulse traverse the fiber using these different paths, and so do not all arrive at the end of the fiber at the same time.
In transmission systems using multimode fiber, this spreading out of photons, or dispersion, within a pulse effectively smears what would have been a clear pulse representing a data bit, and thus limits the number of bits which can be received per second without successive pulses overlapping and interfering with one another.

Multimode fiber systems are able to use LEDs to generate light pulses (which are inexpensive compared to the lasers used in single mode systems), and PIN (or APD) detectors. Because of its lower cost, and the fiber's lesser sensitivity to damage from bending, it is a popular choice for customer premises.
