Optical Port in CPU

There probably is some in research and development somewhere to see if all the added work is worth the effort but I suspect that there will never be a commercial version made available. I say this because all tiny field effect transistors are photosensitive. So getting the optical port transistors to respond to the incoming light is relatively easy. Getting the rest of the transistors in the CPU logic and local memory to not randomly change state from light reflecting around the cavity is rather difficult.

so we must use only media converters for this purpose?

Of course not. Depending on how much of a budget you have, you can get almost anything fabricated today. If you can conceive, design, redesign and most importantly pay for everything then nearly anything can be done. If it were my money, I'd go with an established single board computer that already has the complete infrastructure of CPU, memory, firmware, operating system, I/O interrupt and human to machine programing already established. But I do not know the complexity of your project nor the size of your budget to say anything further.

I'm going to assume you're asking about connecting to a fiber optic lan and you don't want to convert from fiber to copper? If that's the case, search for a fiber optic network card. Not saying that this is the best for what you're doing but I would imagine you're looking for something similar to this.

I vaguely remember that old SUN Micro-systems (now Oracle) used to have optical motherboards as far back as 10 years ago, but the average guy would have had to take out a 2nd mortgage on his house to buy one! Maybe you could find an old Sun Workstation, which might be simiaffordable now.
