Can single-mode fiber be used for multiple locations

Signal Transmission: Single-mode fiber transmits light in a single path. This increases the risk of signal weakening and errors over long distances. Single-mode. Choosing between single mode and multimode fiber is a common decision when designing, deploying, or upgrading fiber optic networks. Although both carry data through light signals, they differ significantly in transmission mechanism, bandwidth-distance capability, deployment cost, and typical. Single-mode and multi-mode are not just cable colors. Although they can do the same job in some instances, the different construction methods make each of them better suited to certain tasks and budgets. [pdf]
