Which type of optical fiber is typically used for campus or building applications due to cost-effective transceivers?

For campus or building networks, links are short enough that we can use inexpensive light sources and receivers. Multimode fiber has a larger core, which makes coupling light from LEDs or VCSELs easier and cheaper than the precision lasers required for single-mode fiber. Because the distances involved are relatively short, the higher modal dispersion of multimode fiber doesn’t prevent achieving good bandwidth, so you get a cost-effective solution with simpler transceivers. Graded-index is a subtype of multimode designed to reduce dispersion, but the overall cost advantage for campus links comes from using multimode fiber with affordable transceivers.
