Raman amplification /ˈrɑːmən/ is a way of increasing the signal strength in an optical fiber. It is often used in a fiber that carries a signal for a long distance (such as in an undersea cable). Technically, it works by stimulating Raman scattering, in which a lower frequency 'signal' photon induces inelastic scattering of a higher-frequency 'pump' photon in an optical medium in the nonlinear regi.

For fiber optic connectors to mate between each other they need couplers, also called adapters, these elements come in many versions allowing to connect simplex or duplex cables. However, setting up a fiber optic connection to your router can seem daunting if you're unfamiliar with the process. Unlike active devices like switches or transceivers, couplers require no electrical power to function. These can behave like a typical Ethernet switch.
