optical microphone cables

Forgive my mistake,

Do you know more about fiber optic cables in microphones? Is the construction of such a cable the same as with other fiber optic cables, What is its construction, what are the known types and manufacturers?

I have never heard of optical microphone cables, so thats probably why you are not getting any search results.

optical microphones and their cables

Do you know anything about optical microphones and their cables? Unfortunately, I didn't find much information from Google and I need it for a written work. What are the most famous types, their construction, the most famous manufacturers, etc.

Thanks in advance

There's a Japanese company that makes or made optical microphones. Used by Japanese broadcast and by industry in places where conventional microphones can't be used. I just can't remember the name of the company. And, no, it's not Kenwood, even if they held one of the many patents. The Kenwood patent seems to have ended up with an Israeli defense company that's only interested in cyber defense these days.

There's also Optoacoustics:

And even Sennheiser has one these days:

The cables used are diverse, as some optical microphones use a LED as light source, while others use a laser diode. There's very little info about the membrane and some even claim not to have a membrane. Of course, there's even a MEMS variant, but again, I forgot who makes it.

The microphones are very expensive but very promising. Cables can be kilometers long without any interference. Frequency range extends into the ultrasonic easily. They are also insensitive to heat, water, chemicals, radiation...
