    I was looking around weird stuff and found this 4 cable wrapped in flame proof techflex with BNC connectors. 15' bundles were $10. I figured... $20 for 30' of techflex seemed like a bargain, the cable might be worthwhile. There are 4 lines, R-G-B and a fouth.

    The cable is Belden but after that I'm not sure, it looks like switching cable.

    The cable is labeled:
    BELDEN YR23028 AWM STYLE 1354 E12683 VW-1

    After searching on google I came up with this being a switching cable.

    BELDEN E12683 TR SWITCH CABLE ASSEMBLY LJ98
    Cabletron 9380141

    Does anyone know what this cable is, what it's specs are and if it would be good as component video cable? I've hooked it up and it looks good. I just want to know what this cable is best suited for.

    Well, I watched a bit of DVD material using the cables and they look good. I'm not sure what that means, because just about any ok cable should at least look good.

    The belden site is back up, but I'm getting no where searching there. Maybe I'll just call them Monday.

    Kewl, Belden is great! I called and the info and specs are being faxed to me. I'll know shortly what this is exactly. I know it was custom made for some company called Quintech maybe these guys, http://www.qecinc.com/ ? Seems like this is a good match and the cable might be good.

    I have to ask one more time.... does anyone know if these specs look fine for component video? The cable doesn't look quite as good as Canare L-5CFB or Belden 1694A, but is it good enought?

    How long does cable last? When do you know to replace it?

    It has a few strikees against it. It is RG59, it is a steel core conductor rather than all copper, FEP insulation is slightly better than PE. It is probably intended to be video cable, but not premium stuff.

    If your happy with it, use it until you aren't anymore, then buy/make something better out of either the Belden or the Canare you mention above. You will likely see an improvement.
