SMU MTx Onet 5 Gb eye diagrams
From Kent I loaded all 20 pieces of VCSELs on to that 10 MTx boards and tested all of them. The results are much better than previous and attached here. When they were biased at 6 mA and modulated at 8 mA, all 20 channels passed the mask. The VCSEL indices in the column B of the Excel file are matched the number on the plastic box as in the picture below
