The coherent 100G transmission systems from network equipment vendors are showing an amazing robustness and tolerance for high PMD and CD. Some are reporting a PMD tolerance of up to 100ps DGD and above, while the CD tolerance can be in the range of up to 50.000ps/nm. Therefore the ideal network for deploying…(Read More)
There are a number of challenges to achieving 100Gb/s optical transmission rates using the technologies that have been deployed at 10Gb/s and even 40Gb/s. Using traditional transmission technologies such as NRZ modulation on the line will result in very poor spectral efficiency and a 100G signal using NRZ would not fit into…(Read More)
