WebApr 1, 2024 · Beginning in the mid-1980s, fiber optic installations expanded rapidly all over the globe, and generations of improved systems followed quickly one after the other. Fiber had enormously higher capacity, which increased even further with each generation, and much cheaper operating costs. Signal loss in optic fiber is measured in decibels (dB). A loss of 3 dB across a link means the light at the far end is only half the intensity of the light that was sent into the fiber. A 6 dB loss means only one quarter of the light made it through the fiber. Once too much light has been lost, the signal is too weak to recover and the link becomes unreliable and eventually ceases to function entirely. The exact point at which this happens depends on the transmitter power and the sensiti…
