If your apartment is already connected to the fiber network, it is also equipped with an OTO plug (OTO = Optical Telecommunications Outlet). In general, there is only one OTO plug per apartment. Usually this OTO plug is located next to the main telephone plug. Each OTO plug carries a unique identification number, e.g. B.012.345.678.9. Older models may carry a number in a different format like WP1234567.

The optical connector is a hard wired device on which the optical fiber ends. This optical socket is the optical interface between the connected equipment and connection to the Internet.

The following illustrations show you the different types of OTO plugs used in Switzerland:
