Stupid builder - need suggestions / help

A few years back had an extension built onto my house and as it was going to be the location of my new study I decided to move into the 21st century and get some ethernet cables put in from my office to a couple of adjoining rooms. I watched the cables being layed down and they are under the plaster in slim metal trunking. Not too sure if they are nailed to the brickwork underneath - but i doubt it. The time came to put the faceplates on the sockets but my electrician said he had no faceplates in his van and would have to come back tomorrow. I told him not to worry as I had a few spare from a previous job and would do it myself. Recently, I finally got around to doing this job few days later when I came to do the job I realised to my horror that the installed cable was not cat6 as I had wanted. In fact it was nothing like cat6. So now I am a bit stuck. The installed cable has "CEAM CAV1 SPECIAL1 SPA - Y09538 - 8xAWG24/7" written on it. I am wondering if this will be anygood at all for running a gigabit network on. The cable runs are not very long, 10m at the very most I would say, and do not cross any power lines in the walls. Or should I just go and buy some cat6, tape one end to this CAV1 and yank the other end of the CAV1? If anyone has any information or tips about what I should do please reply.

I'm trying to google this cable, but I keep getting links to Italian sites about some dude named Cavi... lol.

Um, so long as you make sure you crimp those cables the same at each end, there shouldn't be a problem using those for networking...

You should at least try that before ripping your wall apart!

Generally the cable will list its category further along the cable. I would try putting on an end and seeing if you can in fact reach 1GB speeds.

If you need to or want to repull cables, the best thing to do it use black electrical tape and heavily tape a new wire onto the existing pulled cable. When you pull the old cable out from the other end, it will fish your new cable through. Alternatively, you could run circular line through and use it as a pulley revolving around 2 wheels, one at each end. This way you would just tape the cable onto the line, wheel it through and you can run as much as you would like.
