Due to much lower attenuation and interference, optical fiber has large advantages over existing copper wire in long-distance and high-demand applications.

However due of the low attenuation of ELF waves this tiny radiated power was able to communicate with submarines over about half the Earth's surface.

Such low attenuation ushered in optical fiber telecommunication.

Due to low attenuation of 0.2dB/km in optical fiber cables, it is possible to achieve long distance communication efficiently over information capacity rate of 1 Tbit/s.

Shielded plugs are more expensive and require shielded cable, but have a lower attenuation and can reduce signal noise.

Such low attenuations made fiber optics practical for telecommunications and networking.

For maximum throughput scheduling, links that are affected by low attenuation should be considered as inexpensive, and should be given scheduling priority.

Dispersion-shifted fiber (DSF) is a type of optical fiber made to optimize both low dispersion and low attenuation.

This is advantageous because it allows a communication system to possess both low dispersion and low attenuation.

A higher quality factor implies a lower attenuation, and so high Q systems oscillate for long times.
