What is Power over Fiber?

Power over fiber is a technology that transmits power to electronic devices through light in optical fibers. The birth background of this technology is mainly to solve the problems existing in traditional power transmission methods, such as electromagnetic interference, electrical noise, electrical safety and other problems. The emergence of this technology allows data and power to be transmitted through the same optical fiber, greatly improving transmission efficiency and safety.

1. Related theories

The working principle of power fiber mainly includes two parts: photoelectric conversion and electro-optical conversion. Photoelectric conversion is the conversion of optical signals into electrical signals, while electro-optical conversion is the conversion of electrical signals into optical signals. In power fiber, the light source (such as a laser) converts electrical energy into light energy, transmits it to the target device through optical fiber, and then converts the light energy back to electrical energy through the photoelectric converter for use by electronic devices.

2. Important parameter indicators

The important parameter indicators of power fiber mainly include the power of the light source, the transmission loss of the optical fiber, the conversion efficiency of the photoelectric converter, etc. Among them, the power of the light source directly determines the transmission power of the power fiber, the transmission loss of the optical fiber affects the transmission distance of the light energy, and the conversion efficiency of the photoelectric converter affects the overall efficiency of the power fiber.

3. Applications

The application of power optical fiber is very extensive, mainly including communications, medical, military, aerospace and other fields. In the field of communications, power optical fiber can be used for remote power supply and data transmission; in the medical field, power optical fiber can be used for power supply of medical equipment; in the military field, power optical fiber can be used for power supply of radar, missiles and other equipment; in the field of aerospace, power optical fiber can be used for power supply of spacecraft.
