NVIDIA Mellanox® MCP7H60-C02A — 200GbE QSFP-DD to 2× QSFP28 Passive Copper Splitter, 2.5m
Technical Identity
The NVIDIA Mellanox® MCP7H60-C02A is a 2.5-metre passive copper DAC splitter cable that breaks one QSFP-DD switch-side port (200GbE, 8× 25G NRZ) into two QSFP28 adapter-side ports (100GbE each, 4× 25G NRZ). The MCP7H60-C series is Ethernet only — there is no InfiniBand mode on this part. The assembly is fully passive (no ICs, no power draw) and presents EEPROM identification on every connector for host-side DDM and topology discovery.

What This Is NOT
- NOT an AOC. This is passive copper; reach is limited by twin-axial signal integrity (typically ≤3m at 200GbE NRZ).
- NOT a transceiver. Fixed-length cable assembly with permanently attached connectors — ends are not field-replaceable.
- NOT a 1-to-1 cable. Hybrid switch end / adapter ends: one QSFP-DD on the switch side fans out to two QSFP28 on the adapter side.
- NOT InfiniBand. The MCP7H60-C series is Ethernet only. For HDR/HDR100 InfiniBand 200→2×100 splitters use the MCP7H50-V series (QSFP56 family).
- NOT 400GbE. The MCP7H60-W series is the 400GbE QSFP-DD → 2× QSFP56 part; the -C suffix denotes the 200GbE Ethernet variant.
- NOT bundled with adapters, transceivers, or rail kits — sold standalone.
Compatibility
- Switch side (QSFP-DD): NVIDIA Spectrum-2 (SN3000-series), Spectrum-3 (SN4000-series), Spectrum-4 (SN5000-series), and third-party 200GbE QSFP-DD switches (Cisco Nexus 9300-GX, Arista 7060X4, Dell Z9332F-ON, HPE / Aruba 200G QSFP-DD platforms) configured for the 1×200G → 2×100G breakout port profile.
- Adapter side (QSFP28): ConnectX-5 EN, ConnectX-6 Dx / Lx, ConnectX-7 in 100GbE QSFP28 mode, BlueField-2 DPU 100GbE ports, or any standards-compliant 100GbE QSFP28 NIC or switch port.
- Reach: 2.5m fixed — intra-rack runs (top-of-rack to server within the same cabinet).
- Power: none required; host SerDes drives the link directly.
- Cage requirement: the QSFP-DD end will not seat in a QSFP28 / QSFP56 cage; the QSFP28 ends will not seat in a QSFP-DD cage. Cage type must match exactly.
Deployment & Use Cases
- Port density doubling: turn a 32-port 200GbE QSFP-DD leaf switch into 64× 100GbE access ports.
- ToR to dual 100GbE servers: a single uplink ASIC port feeds two ConnectX-5 / ConnectX-6 hosts.
- 100GbE storage fabric: QSFP28-equipped NVMe-oF, Ceph, or VAST nodes hanging off a Spectrum-2 / Spectrum-3 leaf.
- AI / HPC east-west: RoCE v2 east-west traffic where the leaf is 200GbE-native and the compute nodes are 100GbE-native.
FAQ
Q: What is the NVIDIA Mellanox MCP7H60-C02A?
A: A 2.5m passive copper DAC splitter that breaks one 200GbE QSFP-DD port into two 100GbE QSFP28 ports. Ethernet only.
Q: Will this work on InfiniBand HDR fabrics?
A: No. The MCP7H60-C series is Ethernet only. For HDR/HDR100 InfiniBand 200→2×100 splitters use MCP7H50-V series (QSFP56) cables instead.
Q: Which switches accept the QSFP-DD end?
A: NVIDIA Spectrum-2 / Spectrum-3 / Spectrum-4 (SN3000 / SN4000 / SN5000 series) configured for 1×200G → 2×100G breakout, plus third-party 200GbE QSFP-DD switches from Cisco, Arista, Dell, and HPE with matching breakout port profile.
Q: Can I plug both QSFP28 ends into different servers?
A: Yes — that is the intended fan-out. Each QSFP28 end is an independent 100GbE link; they can land in separate hosts, different cards in the same host, or two switch ports.
Q: What is the condition?
A: Refurbished Grade A. Link-up validated, cosmetically inspected, EEPROM read verified, and bench-tested by T.E.S IT-SOLUTIONS before shipment.
