The short answer is no - RJ45 connectors are designed for electrical Ethernet signals, while fiber optics transmit light pulses through glass or plastic. However, modern networks often combine both technologies. Fiber optic cables and Ethernet cables are two of the most important data transfer cable standards there are, but with their use cases often crossing paths, and colloquialisms even meaning each name is used interchangeably at times, it's important to know the differences with Fiber Optic Cables vs. Another advantage of fiber optic technology is its immunity to electromagnetic interference (EMI). As we enter 2024, understanding the key differences between these two technologies, their recent advancements, and their ideal use cases. While fiber optic cables have advantages in transmission speed and distance, LAN cables still have their place in various applications due to their low cost, ease of use, and ability to transmit both data and power.
