Macroreer 400G QSFP-DD Transceiver Modules includes QSFP-DD SR8, QSFP-DD LR4 and QSFP-DD DR4.
The 400G QSFP-DD Transceiver Modules follows the same port densities system as the QSFP and QSFP28, but the QSFP-DD will support eight lanes instead of four lanes for the QSFP and QSFP28, which double the density.
Each of the eight lanes will operate a data rate up to 50Gb/s providing a 400Gb/s data speed and increasing the capacity of the QSFP28 by four. The 400G QSFP-DD MSA published that the size of the optical transceivers enables to put 36 ports in one switch slot, accumulating 14.4 Tbp/s in one slot.
