Earlier this month, communications expert HUBER + SUHNER unveiled a Global Navigation Satellite System (GNSS) that uses fiber optics to power active antennas rather than traditional copper wires. -Fiber (PoF), almost 10 years.
That way, data and power can be transmitted over just one cable. Copper wires have been used for analog communications for over a century now, but the demand for vast amounts of data coupled with advances in photonics has until recently been limited to very niche applications. means
Although copper is ubiquitous, it has some inherent drawbacks. It cannot be installed where high voltage is generated, can generate electrical sparks, is sensitive to strong magnetic fields, and is relatively thicker/heavier than optical fiber.
how does that work? A light source (usually a laser diode) emits light, usually monochromatic, at one end and a photocell collects the light at the other end. This process is called a light power beam and is basically a smaller, more focused version of how solar panels installed on the roof work.
The latter has an efficiency of around 25%, while Power-over-Fibre can reach up to 70%, but overall, power conversion efficiency is higher when other factors are considered, according to photonics experts. . RP photonics , up to 30%.not enough portable power station For example, or Laptop .
Clearly, we’re not looking to replace wholesale copper across power equipment. It still requires many discrete components and is much more costly than a copper implementation. However, with improvements in technology and mass production, we can expect power over fiber to have a much greater impact in many scenarios.
For H+S, this means that the distance between the source and receiving system can be extended by several kilometers, an order of magnitude compared to copper wire. In the long run, Fiber to the Room could help simplify the deployment of the final frontier, his FTx (Fiber Anywhere). Number of low-power antenna units and nano/pico/femtocells.
There is a great impetus for research in a field that has the potential to thrive: more than 20 conference papers IEEE is the world’s largest technical professional organization dedicated to advancing technology from the beginning of 2022.
