#Fiber Networks Ready for a Revamp, Engineers Unveil Method to Dispel Noise Effects The fiber optic data transmission will soon be enhanced significantly as electrical engineers at the UC San diego Qualcomm Institute have divulged a method to increase the capacity limit of high-bandwidth fiber optic cables. The engineers assert to have broken the apacity limitfor fiber optic transmission which will increase the data transmission rates through the cables. The researchers from the Qualcomm Institute claim that they were able to increase the signal power in a fiber cable by 20 fold which enabled them to send data to a record-breaking 12, 000 kilometres with standard amplifiers and no repeaters. Nikola Alic, researcher at the Qualcomm Institute explained that the current optic fiber cables have limited a capacity to withstand power for signals. Upon crossing the threshold limit, the performance may get poor as noise, distortion and signal attenuation increases. This degradation in signal quality due to increased load is called Kerr effect that necessitates the use of signal repeaters when the data is transmitted along longer cables. Therefore, the new discovery marks a milestone in data transmission as it does not have any limitation with regards to power. The engineers have advocated the use of requency combsto condition signals as this will increase the capacity limit of high-bandwidth fiber optic cables and will eliminate the need of electronic regenerators. Thus, the use of frequency combs will not only radically raise the amount of power that can be sent through a fiber optic cable but will also significantly reduce the cost of fiber networks by doing away with the repeaters r
