There is a nice datasheet. That three rows of SFP connectors will fit into a 1 RU panel seems extraordinary. Hence the work here to show the detail in a line diagram. Perhaps only 32 SFP28 connections will be needed and the center row can be left empty. If more ports will be needed cable routing will require care.
The switch ASIC is a Tomahawk BCM56960. It has 128 SERDES not all of which are used in this switch.
