The Security of Fiber Internet


The advantages of fiber Internet compared to copper have already been discussed in previous weeks. To name a few:

  • Fiber requires less energy and, therefore, is more eco-friendly.
  • Fiber’s advanced technology has a longer lifespan.
  • Fiber has the bandwidth to support multiple devices at once, as well as heavy Internet tasks

Fiber-optic technology is also very secure. If someone attempts to tap a fiber-optic cable, there is a high chance the glass will break. This will probably alarm maintenance professionals, and the attempt is likely to fail.

Additionally, electromagnetic signals are not radiated by fiber-optic cables because they are dielectric, meaning they do not transmit electricity. Therefore, data is nearly impossible to be intercepted by sensitive antennas.

Copper cables, on the other hand, can be picked up by a sensitive antenna. The cable’s radiated energy can be intercepted and eavesdropping can occur. Additionally, the electromagnetic signals can be tapped without any indication.
