Can someone ID this component cable?

I just got this component cable for my original XBOX at a local game store.

It looks like a Monster cable due to it's high quality build and gold connectors, but it has "XBOX" on both ends, and appears to be a genuine Microsoft brand cable. I thought Microsoft only made the High Definition Pack, but I may be wrong. I am looking for a part number or something, because I want another for my brother's Xbox, instead of the cheap kind on ebay

Here it is:

Yes, it is genuine Microsoft product. This component cable is very rare.

Optical audio output on the reverse side of the Xbox connector. It is easy to overlook, it is good find. Low profile, ideal for the boss - so that she can tolerate the Xbox wire tangles under the TV for a few more years to come.

I found one at a local shop for $9

Only one I've seen since.

Ok awesome. I got it for $10, which is cheaper than the HD pack, and I have never seen this before. Goes great with my X3 + X3CP xbox and 2TB drive.
