Cisco QDD-2Q200-CU2M Compatible 2m (7ft) 400G QSFP-DD to 2X200G QSFP56 Passive Direct Attach Copper Breakout Cable for DGX Spark AI Clusters NVIDIA Ethernet Switches (RoCE) the OSFP-800G-2xLR4 enables stable 10

the OSFP-800G-2xLR4 enables stable 10 km optical links for 800G Ethernet deployments

Main use is linking an 800Gb/s Spectrum-4 switch to OSFP-based 200Gb/s ConnectX-7 PCIe network adapter cards and BlueField-3 DPUs

It is also suitable for use in end-to-end InfiniBand EDR systems and compliant with the QSFP28 MSA and the IEEE 802

The Short Reach 4-channel (SR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 50-meters using OM4 multimode fiber and assumes two optical patch panels in the link
