How to split fiber into 2 Ethernet ports?

Hello,
I need your help regarding my Orange fiber wiring; I’m keeping my fingers crossed that you have a solution!

My fiber outlet arriving in my electrical closet next to my front door is preventing me from connecting my fiber cable directly to my box. That's why I needed a fiber box that converts my fiber output to an Ethernet cable, as there’s a whole Ethernet network in the living room, bedroom 1, and bedroom 2. So, with 3 Ethernet inputs available in the closet, I obviously used the living room input.
However, this box only has one Ethernet output (so for the living room), and I would like to send the fiber to bedroom 2 as well.
Is there an Ethernet splitter (1 male turning into 2 males)? If so, would that be dangerous for the fiber box?
I'm counting on you, thank you in advance everyone!

    Hello,
    yes, it's called an Ethernet Switch:
    it can also function as a modem at the same time, but it’s not mandatory.

      Thank you for this quick response!
      However, I see that there is this solution and another one with just a simple splitter, which one would be better and will I have a lot of loss when splitting the fiber?

    Hi,
    forget the splitter, it's not a switch, it will divide your bandwidth by 10 (100 Mbit/s instead of 1000) at best and in this case it won't work for the gigabit signal between the ONT (the powered fiber box) and the router.
    however, it was a mistake to install the router in the living room, it should have been located in the mentioned closet where the fiber arrives and where the patching is done.
    because right now, since you only have one ethernet cable to the living room, not only do you need a switch at the patch panel, but ideally, you would need 2 manageable switches to configure two VLANs for the single cable, one for the fiber and one for the local network, although eventually, both could coexist in two unmanaged switches, in the same VLAN, but that's not very clean :-(
    The only good idea would be to bring the router back to the arrival point and put a basic switch in its place in the living room.

      Thank you, I will indeed forget about the splitter...
      I hadn't put the box in the cupboard because it is connected to the TV decoder and the femtocell, but now that I want to connect a second TV decoder in the bedroom, I will put the box in the cupboard with the femtocell, connecting an Ethernet cable from one of the 5 or 6 available ports on my box to the living room, one to the bedroom, and one for the femtocell.
      Is that how you would see a nice installation?
      And with the femtocell being in the cupboard with my box, won't the Wi-Fi be too negatively affected?
      Thank you in advance.
