400Gbps Qsfp-Dd Sr8

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. 400G QSFP-DD SR8 The 400G QSFP-DD SR8 transceiver supports connections of up to 100 meters over multi-mode fiber and uses MPO connectors. The wavelength is 850nm. It is compliant with the QSFP-DD MSA. Single-mode Transceivers Single-Mode transceivers are more expensive than multi-mode transceivers but they allow to reach longer distance. 400G QSFP-DD DR4 The 400G QSFP-DD DR4 transceiver supports connections of up to 500 meters over single-mode fiber and uses MPO connector. The wavelengths is 1310nm. It is compliant with the QSFP-DD MSA. 400G QSFP-DD DR4+ The 400G QSFP-DD DR4+ supports connections of up to 2 kilometers over single-mode fiber and uses MPO connector. The wavelengths is 1310nm. It is compliant with the QSFP-DD MSA. 400G QSFP-DD LR4 The 400G QSFP-DD LR4 transceiver supports connections of up to 10 kilometers over single-mode fiber and uses LC connectors. The wavelengths are 1296 to 1309nm. It is compliant with the QSFP-DD MSA. 400G QSFP-DD Loopback The 400G QSFP-DD Loopback is a cost effective and high quality solutions to test 400G QSFP-DD transceivers ports.

Product overview The 400G QSFP-DD module (400GBASE Quad Small Form-Factor Pluggable Double Density) is a new generation of 400G transceiver module based on the QSFP-DD form factor.
