4- High bandwidth over long distances.

The Advantages

Fiber-optic systems have a large number of advantages over copper wire cables. Among the most important are the following:

• Because fiber-optic cables are both lighter and smaller in diameter than copper lines, they can be more easily produced and installed.
• Fiber-optic systems use significantly less energy than copper lines and are thus immune to many dangers associated with the electrical current used in copper lines.
• Fiber-optic communication systems can be used to transmit more information than copper cables and are well-suited for use with digital communications.
• When compared to copper cables, fiber-optic cables are both immune to electromagnetic interference and produce no interference when operating.
• Finally, fiber-optic lines are less expensive than copper cables, which can drastically reduce the cost of installing new lines or maintaining older ones.

Primary Uses of Fiber-Optic Communication Systems

Currently, the most important use of fiber-optic communication systems is to provide a low-cost medium to carry an ever-increasing amount of commercial and private data. Where once a slow data connection over a copper line was acceptable, business owners and homeowners alike now demand the ability to stream data requiring several thousand kilobytes per second (Kbps). In addition, the increasing demand for extensive physical cable and internet networks has resulted in a need to drastically reduce the cost and physical space required for installation. In both cases, fiber-optic communication systems are far superior to copper lines. This has resulted in fiber-optic systems becoming dominant in the home and business broadband sector, whether for conventional internet or media streaming services.

The low cost and high efficiency of fiber-optic cables has also resulted in the large-scale replacement of copper undersea and land trunk lines, and has dramatically improved the quality of  long – distance phone and data transmissions. In addition, these systems are far easier to repair or replace as needed, and are not subject to the same data transmission limitations their predecessors faced.

Because of their wide range of advantages when compared to other systems, the use of fiber-optic communication systems is certain to continue to grow at a rapid place. Although most homes currently use fiber to the home (FTTH) technologies, it is almost certain that fiber-optic systems will continue to displace copper lines, eventually replacing them in newly built homes   . Fiber-optic communication systems will continue to be the dominant communication technology of the future.

 

Used for secure traveling  of data and high speed data and no one can iterrupt.

 

fiber optics also -is not like broadband where its in a shared loop system -unlimited broadband speeds ie..
in the US google fiber is as fast as 1GB/sec -very thin cables as thin as a persons hair -less maintenance required -uses light signals -does not erode or get affected by weather -using fiber optics allows you to have each service run independently not like coax and so much more

fiber optics also: - secure.
- transmission long distance (especially marine cables)

Reliability, long –haul transmission and the capacity of optical fiber cannot be compared with any other transmission medium.
