Can fiber optic cables be used for single-mode to multimode connections
Single mode and multimode fiber cables are quite different when it comes to size, light source, signal, and so on. So, they definitely are not interchangeable, and compatibility issues can occur when you try to connect a single mode fiber optic connector to a multimode network. It receives the optical signal on one port, converts it into an electrical signal, and then retransmits it as an optical. These differences determine which transceivers work with which fiber and how far signals can travel.
