Fiber optik sistemlerde veri iletiminin vcsel bazlı erbium katkılı fiber amplifikatör (EDFA) ile iyileştirilmesi

The rapid growth of multi-media and data rich applications has driven the bandwidth demand for long-haul fiber optic links at unprecedented rates. At the same time, growing capacity demands also imposes challenges on bandwidth and interconnects in data centers. Optical fibers are continuing improving their performance to meet the bandwidth demand in both long haul and short reach applications. While continuing improvements in conventional fiber optic technologies will increase the system capacity further in a short term, recent studies show that the transmission capacity over single-mode optical fibers is rapidly approaching its fundamental Shannon limit. A Large capacity optical networks require flattened gain spectrum and large gain bandwidth of the optica
