A fiber coupler is an optical device that connects one or more fiber ends to allow light to travel along multiple paths. It can combine two or more inputs into one output or divide one input into two or more outputs. Compared with splices or connectors, a fiber coupler can attenuate a signal more effectively because the input signal can be divided among the output ports.
