NVIDIA Mellanox MCA4K00 980-9IAM2-00XD01 1.6Tb/s OSFP Active Copper Cable, 1m RHS-to-RHS: This is a 1-meter active copper cable (ACC) engineered for 1600Gb/s aggregate (2x 800Gb/s) point-to-point interconnect using the OSFP form factor with Right-Hand-Side connector orientation on both ends. The cable contains integrated signal-conditioning electronics for extended copper reach. This is a fixed-length integrated assembly, not a transceiver with a detachable patch cord. This is a new unit.
Engineering Context
The MCA4K00 series uses active copper technology with on-cable retimer/equalizer ICs to extend the usable distance of copper interconnect at 200Gb/s per lane PAM4 signaling. Eight electrical lanes per OSFP carry the full 1.6Tb/s aggregate bandwidth. Compared to passive DAC, ACC tolerates signal loss inherent in copper at these bit rates while preserving the deterministic latency advantage of copper over optics. Cable orientation is RHS to RHS, meaning both connector latches face the right side of the rack-facing chassis.
Deployment & Use Cases
Intra-rack and short cross-rack interconnects in AI training clusters built on NVIDIA Quantum-X800 InfiniBand and Spectrum-X 800GbE platforms. Server-to-Top-of-Rack uplinks where passive copper would not maintain signal margin. GPU compute node interconnects to OSFP-equipped switches in dense AI racks. Latency-sensitive HPC fabrics where copper is preferred over active optical cables.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: 980-9IAM2-00XD01
Series: MCA4K00
Cable Type: Active Copper Cable (ACC) with integrated equalizers
Form Factor: OSFP to OSFP (Point-to-Point)
Aggregate Data Rate: 1600Gb/s (8x 200Gb/s PAM4)
Connector Orientation: RHS to RHS
Length: 1m
Condition: New — Tested by T.E.S IT-SOLUTIONS
Compatibility & Hard Constraints
Designed for NVIDIA Quantum-X800 InfiniBand switches and ConnectX-8 family adapters supporting 200Gb/s per lane OSFP ports, and for NVIDIA Spectrum-X 800GbE platforms with OSFP receptacles. Both ends require ports that physically accept RHS connector orientation. Not compatible with QSFP-DD, QSFP56, or earlier QSFP receptacles without an approved mechanical adapter. Active copper requires the host port to provide the standard OSFP power budget for the on-cable retimers; ports configured strictly for passive-only operation will not function. Fixed 1m length and fixed 8-lane configuration; does not support breakout.
