@devopscats if you're pushing that much light, that's concerning

@xssfox guess its for measuring flux inductors rather than capacitors?

@devopscats anything can be a conductor is the voltage is high enough

@jpm @devopscats

If you're putting such a high voltage across a length of optic fibre that 4A (let alone 200A!) current flows… I do NOT want to be near it.

Edit: seems glass dielectric strength starts at 9.8MV/m… so in excess of 39.2MW of power dissipation for every metre of fibre. Yikes!

@devopscats Wasn’t looking closely and I thought those were shielded conductors.

This is much worse.

@devopscats Huh, the new power-over-fiber standard seems to be a huge upgrade ​:blobcat_googly_trash:​

@devopscats I'm extremely sorry to report mdpi.com/2304-6732/8/8/335 Power-Over-Fibre. Some tech can do 40W optical, and that's uhhh 470 gigawatts per m^2 of fibre core (hope you have low loss!)

@devopscats Well I wouldn't touch such cables if there was a significant amount of current going through them.

@devopscats so this one above is obviously funnily wrong, BUT, I was surprised to find out the other day there are actually tools to check if there's light going through fibers and in which direction without unplugging them, they cost a fortune though

Blue and black Optical Fiber Identifier tool that clamps onto a fiber to check if there's light going through it. On the screen on the right it reads "-17.78dBm, 1000hz", on the screen on the left it reads "850nm, -50dBm"

@devopscats Super easy to build that product, it always says zero!

@devopscats alt text: promo image for a current clamp meter, with the meter being held next to some cables, but the cables aren't connected to anything and they're also fibre optic.
