OK, seriously. Let's start with

You would get better answers if you started with an assumption that made sense. A higher quality DVD player will potentially produce better sound than a low quality player BUT, only through the ANALOG outs. The DVD player does not process the signal for the optical out, so the quality of a functional DVD player doesn't make a difference with the optical/digital out.

But, reality aside, assume there is an imaginary difference. Then

Rephrased the question is "will different optical cables transmit the exact same signal equally well"

Optical cables in this case transmit a digital signal (they don't transmit sound). The whole point of a digital signal is that it is very very robust. The whole point of making digital connections in the first place is to eliminate cable quality from the equation. It is easy to tell if the signal is a '1' or a '0' even if the signal is weak or degraded. This means that the quality of the cable matters very very little. Cable quality matters far more for an analog signal than a digital one. There are certain kinds of signal errors that theoretically can occur in optical cables; I suppose some people claim they hear them. Modern DAC's are designed to compensate and correct these errors. A coaxial cable for a digital connection doesn't have these problems, is cheaper, and easier but that's my opinion. The answer to your question is 'yes'. But, I'm a non-believer, forgive me.
