You will need two ports on your switching device, and two cables to this splitter (the combiner?) then one cable onwards through the walls. In your room you have one cable from the wall to the back of the splitter, then one cable to each device. In contrast, if you put in a switch you would be neater and closer to best practice. These splitters don't carry gigabit at all, and some of them can fail to negotiate 100 Mbit. Also, they won't negotiate POE either.
The WDM or Bi-Directional SFP is a compact optical transceiver module used for both telecommunication and data bidirectional communications applications.iberStore BIDI SFP can be produced either with SC or LC simplex port, that is used both transmission and receiving. By offering a standard, hot swappable electrical interface, it can support a wide range of physical media, from copper to long-wave single-mode optical fiber, at lengths of hundreds of kilometers.
