In the datasheets for the 16XGE since release Juniper specifically called out 120G due to bus limit with SCB.
Not in the sheet but actual is guaranteed 30G per bank of 4. We used first 4 of each bank in heavy core use and behavior is as specified. With change to SCBE this limit is removed and _all_ 16 ports are line rate capable at same time. The 30Gbit nominal (actual 31.7 or greater) limit per trio applies to the MPC1 and 2 cards but the quad trio interconnect in the 16XGE is wired up diff with additional helpers and can do the full 40G per bank. There is no increase in usable capacity with the MPC1-3D and MPC2-3D cards with the SCBE though, still 30G. I did not have gear for a 16XGE full test, but after SCBE upgrade I did specifically test at full duplex line rate on all 4 ports in a bank on one card to all 4 ports in a bank on a second card in the same chassis.
