Really shit ethernet splicing / coupling. Unless you don’t have ethernet jacks anywhere, then the cables go to phone jacks that can be converted to ethernet jacks. If you convert them or already have ethernet jacks, I’d get these connections redone properly. The easiest way to do this would be to terminate them with an RJ45 connector and use cable couplers to connect them together.
