Advantages of fiber optics over Copper

The optical fiber has advantages in compared to copper:
- The spread signal undergoes low relief and has no need to be frequently reamplified;
- You can perform data transmission to very high speeds (currently up to 160 Gbit/s laboratory);
- The signals are insensitive to electromagnetic perturbations ;
- It is possible to multiplex several spectrally data types on a single fiber, it transmits multiple channels, each with its own "Color" (or wavelength, or "lambda");
- The optical fiber cables are easier to handle, they can stand ups are important and lighter and more flexible than copper
