To connect multiple Ethernet switches, the best way is to use a multi-strand fiber cable. The 4-strand pre-terminated fiber optic cable consists of four individual strands or fibers of glass or plastic fibers enclosed in a protective sheath. On each floor each ethernet cable will be connected to a router, which will then distribute the internet. Fiber-optic cabling is widely used for high-speed Ethernet links over relatively long distances. The fiber-optic cable itself has several layers made from different materials and having. On the end of the fiber can there be multiple routers? or it's only one router that should route the traffic to corresponding networks A single fiber link (usually two fibers: one for transmit, and one for receive) will have one router on each end, but a router can have links to other routers, so. At some point, the LAN has a switch that connects to a router (R) or routers that connect to the Internet, providing an Internet connection to users and allowing other networks like this one to communicate with each other. Commonly used on LANs with a distance of a few hundred meters but can be up to 2 km.
