Based on the comparison between single-mode and multimode fiber optic cables, it can be concluded that single-mode fiber is ideal for long-distance data transmission and is commonly used in carrier networks, metropolitan area networks (MANs), and passive optical networks (PONs). In contrast, multimode fiber is suited for shorter distancesand is widely deployed in enterprise networks, data centers, and local area networks (LANs). Regardless of the type chosen, selecting the fiber that best meets your network requirements while considering total cost is a crucial decision for any network designer.

Long-distance >500m (or several km) => Single-mode

Short distance <500m => Multi-mode
