Optech’s 400G QSFP-DD Transceivers includes QSFP-DD SR8, QSFP-DD LR4 and
QSFP-DD DR4.

The 400G QSFP-DD Transceiver 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.
