| Abstract: | The article pointed that market demand for 40 Gbit/s is clear now, relevant technologies are mature, cost is approaching the threshold of taking off and mass deployment will start soon. Then, the article analyzed and investigated a couple of key technical issues such as chromatic dispersion, PMD, non-linear impairments, requirement of optical signal to noise ratio, selection of modulation formats, super FEC, selection of color and colorless interfaces, etc.. Finally, the article discussed the status and pro... |
