Assignment 1: Copper vs Fiber




Copper vs Fiber
 
Benefits of  Copper
 
- cheaper and easier to terminate
- availability of copper cables
- tighter bend radius
- common spares and patch panels
- no danger from infra red radiation (laser hazard)
- not prone to poor signal due to dirt and dust
 
Benefits of Fiber Optics
 
- interference immunity from RF and electrical signals (EMI)
- lightweight
- driving distance (thought not a benefit for cabling between switches in the same rack)
- although fiber is not as resilient against mechanical stress, this can be counteracted by using rigid loose sleeved fiber
 
As you can see each technology has its own set of advantages. I would say that the greatest advantage of fiber in any situation is the immunity to electrical interference, which is especially critical at the high data rates such as GE. A few organizations with real world use for Fiber would be in the Military. Time, speed and security is of essence when dealing with real world situations. With the use of Fiber, high-performance fiber optic links that natively transport radio frequency (RF) signals over a wide range of bands including 1 kHz, L-band, S-band, C-band, Ku-band, and Ka-band. Analog microwave signals can be carried over long distances due to fiber’s low insertion loss link distances range from a few hundred meters to fifty kilometers. Applications for RF-over-Fiber include signal transport from remote satellite antennas, military and commercial communication links on ships and airplanes, distribution of timing signals, surveillance analysis systems, delay lines, and secure links between buildings.
