This is apparently a network cable of some sort which I couldn't figure out what it is. Here is the damaged end:

damaged end

And here is the other end:

It was chopped off accidentally by the contractor and he wasn't sure what is it exactly. Anyone is aware of such cable and how do I reconnect it back? Appreciate it. I tried asking in the network section. Someone suspect that it's a telephone cable?

  • What is connected to the other end of that cable?

  • @Tyler looks like an ethernet port or some network devices. I'm not too sure myself. but if I stare at the cable hole, directly underneath is an ethernet port. But as you can see, it doesn't look like a ethernet cable

From my point of view, looks like an optical fiber from isp. Not very clear on the core view.

The elaborate connector on the other end probably will explain it, if you took that photo to an electrical supply house.

  • I was think fiber also + could have been part of a surround sound system.

    2nd for also thinking fiber - that also explains why you can't see any metal traces in the cable. Be careful, you do NOT want fiber strands in your finger. Commented Feb 27, 2017 at 4:30
  • I second that portion about glass fragments, @djsmiley2k. Once they work their way in, the only way to get them out is to either just let them fester (the body will expel it) or surgery. Maybe some electrical tape over the cut end would be appropriate.
