NVIDIA Mellanox MCP4C10 980-9IAL2-00X00A 1.6Tb/s OSFP Passive Copper Cable, 0.5m RHS-to-RHS: This is a 0.5-meter passive direct-attach copper (DAC) cable 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 no active electronics. This is a fixed-length integrated assembly, not a transceiver with a detachable patch cord. This is a new unit.
Engineering Context
The MCP4C10 series carries 200Gb/s per electrical lane PAM4 across eight lanes per OSFP for a 1.6Tb/s aggregate channel. As a passive twinax assembly it adds no signal-conditioning latency and consumes effectively no port power, but the 0.5m length is what keeps insertion loss within the OSFP electrical budget at 200G/lane. RHS-to-RHS orientation means both connector latches face the right side of the rack-facing chassis.
Deployment & Use Cases
Intra-rack server-to-Top-of-Rack uplinks in AI training clusters built on NVIDIA Quantum-X800 InfiniBand and Spectrum-X 800GbE platforms. Short GPU-compute interconnects to OSFP-equipped switches in dense AI cabinets. Latency-critical HPC fabrics where copper is preferred over active optics. Switch-to-switch chassis stacking within a single rack where both ports present RHS receptacles.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: 980-9IAL2-00X00A
Series: MCP4C10
Cable Type: Passive Direct-Attach Copper (DAC)
Form Factor: OSFP to OSFP (Point-to-Point)
Aggregate Data Rate: 1600Gb/s (8x 200Gb/s PAM4)
Connector Orientation: RHS to RHS
Length: 0.5m
Power Draw: Passive — no active electronics
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. Passive cable; the host port must support passive DAC operation at 200G/lane PAM4 — ports configured strictly for active-only modules will not link up. Fixed 0.5m length and fixed 8-lane configuration; does not support breakout.
