The following table and diagrams show the main features of the different 400G transceivers that Arista’s platforms support. All of these transceivers have the same electrical connector interface, which is 8 x 50Gb/s PAM-4 (for a total of 400Gb/s). However, the optical signals can vary depending on the module type. Some modules have 8 x 50Gb/s PAM-4 optical lanes, while others have 4 x 100Gb/s PAM-4 optical lanes. For the latter, a gearbox chip inside the module converts the 8 x 50Gb/s PAM-4 electrical signals (from the board) to the 4 x 100Gb/s PAM-4 signals that the optical signals need.
Block diagrams of each optic listed above are shown below.
