Why send power as light

Galvanic isolation

No electrical connection between source and load — natural fit for high voltage.

Immune to EMI / RFI

Light is unaffected by electromagnetic fields, unlike copper.

No metal in the path

Suited to corrosive, explosive and cleanroom environments.

Stable over distance

Low fiber loss keeps remote supply stable.

How the system works

1. 808 nm laser source

Converts electrical power into 808 nm light.

2. Multimode fiber

SMA905 interface, 40–400 μm core options.

3. LPC receiver

Converts monochromatic light directly into electricity.

4. Remote electronics

Powers sensors, monitoring and communication nodes.

Applications

Sensors & high-voltage monitoring

Isolated power for sensing, measurement and monitoring nodes in utilities.

RF & electromagnetic environments

Optical delivery removes conductive-path electromagnetic coupling.

Industrial & corrosive sites

Where metal wiring is unsuitable.

Avionics & remote nodes

Where cable weight, EMI and power isolation matter.
