It supports link distances up to 2 km over single-mode fiber (SMF) using dual MTP/MPO-12 connectors
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
This extended reach jumper is ideal for connecting high-speed multi-mode equipment across large data center footprints
The ACC contains eight high-speed electrical copper pairs
The SN4700 spine/super-spine offers 32 ports of 400GbE in a compact 1U form factor
NVIDIA/Mellanox Compatible DAC 1m (3ft) 400G OSFP Flat Top to OSFP Flat Top InfiniBand NDR Passive Copper Cable NVIDIA Ethernet Switches (RoCE) It supports link distances upDescription The OSFP 400G DAC Flat Top is a high performance, low latency passive direct attach copper cable designed for 400G InfiniBand networking, AI clusters, and high performance computing (HPC) interconnects. Utilizing an OSFP form factor, it supports four lanes of 100G PAM4 signaling, delivering up to 400Gbps per link. Its flat top design offers improved mechanical compatibility and space efficiency, enabling easy deployment in high density GPU
