 Low loss
    Optical fiber features low loss compared either to the metallic,
balanced paired cable or coaxial cable using copper.

 Wideband
    The optical fiber can transmit signals at far higher frequencies than coaxial cable,
although the frequency range depends on the fiber type.

 The short diameter and lightweight
    The optical fiber is narrower and lighter than other transmission media.
Compared to 18-core coaxial cable, for example,
the 18-core optical cable is about 1/10 in sectional area and about 1/30 in weight.
Optical cable, when compared to conventional metallic cable with the same outside diameter,
can accommodate more conductors and is advantageous in terms of installation.

 Non-inductive
    Since glass such as quartz does not conduct electricity, the optical fiber is free of noise resulting from electromagnetic induction from external objects (such as high-tension cables, TV sets, and radios).
