<Li> Low attenuation loss over long distances: Attenuation loss can be as low as 0.2 dB / km in optical fiber cables, allowing transmission over long distances without the need for repeaters . </Li> <Li> Electrical insulator: Optical fibers do not conduct electricity, preventing problems with ground loops and conduction of lightning . Optical fibers can be strung on poles alongside high voltage power cables . </Li> <Li> Material cost and theft prevention: Conventional cable systems use large amounts of copper . Global copper prices experienced a boom in the 2000s, and copper has been a target of metal theft . </Li> <Li> Security of information passed down the cable: Copper can be tapped with very little chance of detection . </Li>
