In this paper, a practical 40Gb/s 12:16 converter is implemented for VSR parallel optical transmission.
The converter realizes the functions of mapping OC-768 frame to/from parallel optics. Using two chips
of Altera FPGA and Agilent81250, a complete simplex communication experiment system is built.
Detailed design such as frame synchronization, deskew algorithm and converter are presented. In
addition, we design a SFI-5 interface verifying board to verify the deskew function. Testing results are
also given illustrating that the converter works well.
