400Gb/s Transceivers OSFP, OSFP, QSFP112

400Gb/s Transceivers and Fiber Part Numbers based on 100G-PAM4 Modulation for InfiniBand and Ethernet, Twin-port OSFP, OSFP, QSFP112

The 100G-PAM4 cable and transceiver product line consists of DAC, ACC and AOC cables, multimode and single-mode optics. Both InfiniBand and Ethernet are supported in the same device configured as:

800G-to-800G links for switch-to-switch

800G-to-two 400G links to ConnectX-7 and BlueField-3 DPUs

800G-to-four 200G links to ConnectX-7 and BlueField-3 DPUs

Important notes:Twin-port OSFP finned-top devices are only for Quantum-2 InfiniBand and SN5600 OSFP Ethernet air-cooled switches.

Twin-port OSFP transceivers must use the same fiber type (straight or splitter) and not one of each.

400G OSFP ends are only for ConnectX-7/OSFP.

400G QSFP112 ends are only for ConnectX-7/QSFP112 and BlueField-3/QSFP112 DPUs – not for switches.

100G-PAM4-based transceivers cannot downshift to 50G-PAM4.

400G OSFP and QSFP112 transceivers contain the same electronics and optics and can be both used at the same time on a twin-port OSFP 800G transceiver in a switch.

800G twin-port OSFP finned and flat top transceivers contain the same electronics and optics.

800G to 800G, 400G and 200G DAC, ACC and Transceiver Summary
