I have fiber internet through my provider. I honestly have no idea how it works, but in my basement near my foundation I have a cluster F of spliced together, tied together ethernet cables. Long story short, one ethernet cable runs the length of my house through the basement and up through the floor to my office where my wireless router sits. Along the run, there is another splice where the cables are wired together. I've done quite a bit of cabling and punching down ethernet in the past, but I've never seen ethernet wires tied together like this before.
Anyway, what I'd like to do is have a gigiabit router/switch right where the ethernet starts in my basement, then use the existing run to continue to feed the office, and run additional cables from the switch up to my bedroom and my living room. Here's my floorplan:
I'm sorry it's crappy and small. The red dot on the right labeled "1" is where the first mess of ethernet starts. Here's a picture of the various cables spliced together:
That runs the length of my basement to the red dot labeled "2", where I'm guessing the installer just ran out of cable and manually spliced more cables together? This is where I'm thinking about disconnecting it and bringing the cable back to red dot #1 to connect to a gigabit router. Here's a picture of the splice:
Then from the router in the basement, I would run another ethernet cable to splice back into the run that goes up into the office (blue dot #3) that I just disconnected. I would run additional cables to blue dots 4 and 5 in my bedroom and living room.
The question is, I'm scared of those splices... I guess I would feel more comfortable terminating them with with male connectors and tying them together with a female-female connector. Is it safe to assume that it's just a standard ethernet cable and the installer just bypassed terminating the cable by "twisting" the wires together? Is it safe to undo?
