What does RHS-to-RHS orientation mean?

RHS (Right Hand Side) orientation means both OSFP connectors have the latch mechanism on the right side. This is specific to certain switch port layouts. Verify your equipment port orientation before ordering.

Is this cable passive or active?

This is an Active Copper Cable (ACC) with internal retimer electronics. Unlike passive DACs, it draws power from the host ports and actively conditions the signal for reliable 1600Gb/s transmission.

What is the difference between this ACC and a passive DAC at 1600Gb/s?

At 1600Gb/s with 16 lanes of 106.25Gb/s PAM4, passive copper cannot maintain signal integrity. The ACC uses active retimer electronics to ensure reliable data transmission, which is why it requires power from the host ports.

NVIDIA Mellanox MCA4K00 (980-9IAM2-00XD01) 1600Gb/s OSFP to OSFP Active Copper Cable, 1.1m, RHS to RHS Orientation: This is a 1.1-meter active copper cable (ACC) delivering 1600Gb/s (1.6Tb/s) aggregate bandwidth between two OSFP ports. The cable uses active signal conditioning electronics to maintain signal integrity over copper at XDR-class data rates. The RHS (Right Hand Side) to RHS connector orientation is specific to certain switch and adapter port layouts. This is a refurbished unit.
Engineering Context
At 1600Gb/s, passive copper cannot maintain signal integrity over any meaningful distance. The MCA4K00 uses internal retimer/redriver electronics to condition the 16 lanes of PAM4 signaling (16x 106.25Gb/s per lane). Unlike passive DACs, this cable consumes power from the host ports. The RHS-to-RHS orientation means both OSFP connectors are oriented with the latch mechanism on the same side, which is critical for correct insertion in certain switch port layouts where all ports face the same direction.
Deployment and Use Cases
Ultra-high-bandwidth interconnects between next-generation NVIDIA switches and DPUs. AI SuperPOD and GB200-class GPU cluster wiring requiring 1.6Tb/s per link. Spine-to-spine or spine-to-leaf connections in XDR-class InfiniBand fabrics. Short-reach in-rack connectivity where optical solutions are not required.

Compatibility and Hard Constraints
OSFP Ports Only: Both ends are OSFP. Not compatible with QSFP-DD, QSFP56, or QSFP28 ports. Orientation Matters: RHS-to-RHS means both connectors have the latch on the right side. Verify your switch port layout before ordering. Incorrect orientation prevents proper insertion. Active Cable: Unlike passive DACs, this cable requires power from the host ports and contains active electronics. Verify port power budget supports ACC cables. 1600Gb/s Class: Designed for next-generation XDR-class platforms. Verify switch and adapter firmware support for 1.6Tb/s signaling.
