The job of the second month to do a simple statement this month mainly did the following work:1, Test Yanshan teaching pass (after the test for teaching pass to each project team, so the original plan to carry out the Dalian Project test not carried out) 2, Learning new EDC baseline on the platform of Yu Beiping (Xining EDC needs not come out before, learning related structure) 3, Qinghai every Wednesday ro

it can use the powerful Electronic Dispersion Compensation (EDC) capability to clear signal distortion at a very low cost. Therefore, through the use of 100 Gbit/s PM-QPSK and EDC, coherent detection technology can be improved by 6 dB (compared with the direct detection of OOK); the use of high encoding gain FEC can be improved by 2 to 3 dB; because the transmission cost of CD and PMD is reduced, 1-2 dB is
