Transferring power is nice, but 1 Watt, is it even enough to run the fiber to electrical signals conversion in the receiver or even enough for a halfway point repeater? Also loosing 1 wavelenghts on 4 fibers to do so, I am not able to find a definitive fiber transfer rate but fairly cheap 48Gbit HDMI can run over fiber, so roughly guessing 1 watts of powertransfer uses the same bandwidth as 4X channels of 48Gbit = 192Gbit data (internet for a small town). They should probably keep running normal cheap power cables in the fiber cable for many years still.

This isn't loosing how many fibers can be used cause it's a standard size fiber with 4 within it. This also isn't for power transfer say like, powering a town. This is more to power whatever devices are on the end to keep the system on. Also good for powering remote sensors.

This is a proof of concept and not meant to be deployed. As this technology matures it could provide a number of applications including direct power and data sourcing to extremely delicate technology such as high tech and military grade sensors and is also resistant to electrical magnetic fields, metal based power cables create electrical magnetic fields that disturb data transmission and require constant signal verification and error correction. This is certainly not meant to be used as an alternative means of powering our neighborhood. Also, you can not run HDMI 2.1 over fiber at 48Gbit for long distances, not to mention 14 kilometers, HDMI 2.1 is intended for short distances and the HDMI over cable still require copper, gold or silver end connectors and to extend the data transmission length length you would need receivers and transceivers. True optical fiber can run up to over a 1.5 Pbit at 20 + kilometers and 10's to 100's of Tbit for dozens to hundreds of kilometers depending on the number of channels and wavelength used.

The power transfer light is full on in 4 fibers, no other data can be transferred on that wavelength, making it impossible to access that bandwidth blocked by power transferring. Switching the power light in any way to claim back space for data traffic, will cut into the 1W power transfer capability.

A super slow 2 fiber 10Gbit simple fiber converter from fiber to electrical signals use 1W, so the power budget is already gone, before there is anything left over to power any form of thinking processor or memory or sensor. They would need to improve the system massively to be usable or use a supercap and run everything in small bursts to have enough power. Metal based power cables do not disturb data transmission if the data is fiber, no error correction is needed. Transatlantic cables for example are already shielded and armored with multiple layers of metal around the fibers, putting in a power cable next to the fibers would be easy and is already shielded very well with the armored cable. There is no such thing as "true optical fiber" there are only multiple different standards to follow, not true or false fibers. The world record for fiber transfer on one fiber is 1.8 Petabits/sec and the record holder themselves write that they split one color to hundreds of colors to manage those kinds of speeds, my example was one color only, to keep the power down on the receiving end.

if its efficiency is decent , then you potentially have something interesting on your hands, scaled up, would have a number of advantages , such as emf and arc free operation and fewer transformers, cost savings at scale at scale, resistance to interference. infact it may be necessary period , since the electrical grid is extremely vulnerable to CME and EMP events , a carrington class event today would simply fry everything , if the grid were optical, the damage would be greatly reduced.

Fiber laser cutters and cinema laser projectors needs a water chiller to cool the light source, for example 10,000 watts laser needs a 5,000W waterchiller to cool the light source. The light receiver would likely also need a waterchiller to not burn up. Hope that gives you an idea of how efficient power transfer via light is at this point in time. Personally i think Microwave power transfer in a waveguide is more efficient then light in a fiber if we are talking 1,000+ Watts power transfer. But all this is unneeded with local power plants like solar, wind, mini reactors or other power generation, if EMP vulnerability solving really was a priority. Underground or underwater cables are much more shielded then wires above ground, so digging cables down deeper would be a more practical solution, if more shielding really was a priority, metal shielding above the powerlines in the ground could be used to soak up the EMP power.

I think that's a bit hyperbolic, lasers diodes can be pretty efficient, and if you need cooling , full submersion,reservoirs or seawater are relevant options, and waste heat can be recovered to an extent. EMP vulnerability hasn't been addressed merely because the powers that be be don't really care or worry about anything more than 5 years in future to be frank. One can only hope that People planning future infrastructure upgrades, will replace above ground lines, and find other means of shielding above ground infrastructure.

Laser diodes are generally around 50% efficient in turning power into light, but they can be upto 80% under ideal situations. Lets be nice and say 75% efficient for something like this and that is only to get light into the fiber, extracting the light again is atleast 25% loss again. Charging 1 electrical car would be enough waste heat to heat up a home in the winter just from the fiber conversion and would require 100.000 fibers if 1 Watt lasers are used.

you can recover waste heat, in an application like high power transmission lines , this is less of an issue, i dont think anyone is suggesting to replace charging cables with optics, transmission losses today can be up to 50% in some places

Look it up please. Transformer loose 1-2% High voltage power lines loose 2-6% depending on the distance. Transformer again looses 1-2% Total loss is less then 10% for an average high voltage transmission line.

as i said depends on where you live, not everywhere has efficient infrastructure. https://electrical-engineering-portal.com/total-losses-in-power-distribution-and-transmission-lines-1 The 50% figure as I recall comes from developing countries, where infrastructure is inefficient, and availability of power is poor. in such places simply " building more power plants" is not really a viable solution, unless are you building fuel powered plants. And since this is getting derailed .I should reiterate my position is not that optical is superior or equal to copper lines, merely that it maybe viable as an alternative or comparable/preferrable in some situations, that is all. I will also add that All of this is purely hypothetical, Isn't meant to be super serious.
