NVIDIA Mellanox MCP7Y70-H002 HDR Splitter Passive Copper Cable, OSFP Twin-Port to 4x QSFP56, 2m LSZH: This is a 2-meter passive copper splitter (DAC) designed for InfiniBand HDR fabrics that connect Quantum-2 OSFP twin-port switches to ConnectX-6 HDR/HDR100 endpoints (NVIDIA P/N 980-9I93O-00H002). The OSFP twin-port end carries two 200Gb/s HDR ports aggregated through a single OSFP cage; the four QSFP56 legs each terminate one 100Gb/s HDR100 link. This is a refurbished unit tested by T.E.S IT-SOLUTIONS.
Engineering Context
The MCP7Y70-H002 splits 2x 200Gb/s HDR signaling into 4x 100Gb/s HDR100 lanes, each carried over 2x 50Gb/s PAM4. The cable uses 28 AWG twinaxial conductors with a Low Smoke Zero Halogen jacket. As a passive DAC, it requires no external power and adds negligible latency compared to active optical alternatives. The 2-meter length is the sweet spot for in-rack and adjacent-rack splitting where the OSFP twin-port host switch is densely populated and reach is short.
Deployment & Use Cases
Connecting Quantum-2 OSFP twin-port switches operating in HDR mode to four ConnectX-6 HDR100 HCAs in adjacent compute nodes. Doubling effective HDR100 port density on Quantum-2 switches deployed in HDR-only clusters. In-rack HDR/HDR100 fan-out for HPC and AI training pods where the host endpoint count exceeds switch port count. Storage interconnect to NVMe-oF arrays equipped with HDR100 ConnectX HCAs.

Compatibility & Constraints
Compatible with NVIDIA Quantum-2 switches in OSFP twin-port HDR mode and ConnectX-6 VPI HCAs operating at HDR100. Requires the host OSFP cage to be configured for HDR twin-port operation, not NDR. Not compatible with NDR-only Quantum-2 ports, NDR200 OSFP cages, or single-port OSFP NDR connectors — the lane structure and port assignment differ. Not compatible with Ethernet QSFP-DD or 400GbE host platforms. As a passive DAC, reach is fixed at 2m.
Why T.E.S IT-SOLUTIONS
Every refurbished DAC is electrically tested for lane integrity and connector seating before shipment. T.E.S IT-SOLUTIONS ships globally with 1-3 day handling and provides expert consultation on InfiniBand HDR splitter topologies and warranty support.
Frequently Asked Questions
What aggregate data rate does the MCP7Y70-H002 have?
The MCP7Y70-H002 aggregate data rate is 2x 200Gb/s HDR (400Gb/s aggregate), as listed in the specifications for MCP7Y70-H002.
What is the MCP7Y70-H002 NOT compatible with?
Not compatible with NDR-only Quantum-2 ports, NDR200 OSFP cages, or single-port OSFP NDR connectors — the lane structure and port assignment differ. Confirm fitment against your platform before ordering MCP7Y70-H002.
