coax cable , but not RG6?

I tried to google this stuff and got nowhere, but I have been given a length of cable that has the name Alcatel on it, and the letters BSW , can't figure out what it is. A friend found this at a yard sale and thought I could use it. There's maybe 75' or so, has yellow ooze coming out of the ends, like flooded rg6, but it isn't that. Has the 'feet' markings on the coax jacket, and I cut into it with a knife to see what I could find. I hit a layer of spiral-wound copper, and quit cutting. Anybody familiar with what this might be? I don't think it will be any use to me at all.
