Cable Types: OSFP-1.6T-CU1FH

Brand: NVIDIA/Mellanox (InfiniBand)

Cable : 1m (3ft) NVIDIA/Mellanox Compatible 1.6T DAC OSFP224 RHS/Flat Top 8x200G PAM4 to OSFP224 RHS/Flat Top 8x200G PAM4 InfiniBand XDR Passive Direct Attach Copper Cable for 1.6T RHS NVL5 Switch and ConnectX-8 NICs

The NVIDIA/Mellanox compatible 1.6T OSFP224 RHS/Flat Top Passive Direct Attach Copper Cable (DAC) is a high-performance 1m (3ft) interconnect solution engineered specifically for next-generation InfiniBand XDR and 1.6T Ethernet networking. Supporting 1.6Tb/s (8x200Gb/s PAM4) ultra-high-speed transmission, this passive cable features a Riding Heat Sink (RHS / Flat Top) connector shell design that maximizes thermal efficiency and ensures optimal space compatibility in high-density switch cages and liquid-cooled data center environments.

100% verified and tested on original systems to guarantee seamless compatibility with NVIDIA XDR infrastructure, passive DAC technology delivers near-zero power consumption (<0.1W) and ultra-low latency without digital signal processing delays. Featuring a high-shielded copper structure with ultra-low insertion loss, it provides an ideal, highly reliable interconnect for short-reach, rack-scale deployments such as 1.6T RHS NVL5 switch-to-switch links, 800G ConnectX-8 OSFP SuperNIC connections, and high-density GPU server clusters.
