Definition of 400G QSFP-DD Transceivers
QSFP-DD stands for Quad Small Form Factor Pluggable Double Density. 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.
Multi-mode Transceivers
Multi-mode transceivers are the low cost transceivers. QSFP-DD SR8 use more expensive non-standard MPO connectors which cancel out some of the cost savings of the multi-mode transceiver.
