NVIDIA Mellanox® MCP7Y50-N002-FLT — NDR 800Gb/s Twin-Port OSFP to 4 × OSFP NDR200 Passive Copper Splitter DAC, 2m, Flat-Top
Technical Identity
The NVIDIA Mellanox® MCP7Y50-N002-FLT is a 2 m passive copper 1:4 splitter direct-attach cable. A single twin-port OSFP connector carries 800 Gb/s as 8 lanes of 100 Gb/s PAM4, split inside the assembly into four OSFP legs of 2 × 100 Gb/s = 200 Gb/s NDR200 each. The FLT suffix denotes flat-top (finless) OSFP housings, intended for host and adapter cages rather than the finned-lid variant used on air-cooled switch ports. Protocol: InfiniBand twin-port NDR / NDR200. Condition: New, factory-sealed.

Lane & Signal Logic
Head end: 8 lanes × 100 Gb/s PAM4 = 800 Gb/s on one twin-port OSFP
Split ends: 4 × OSFP, each carrying 2 lanes × 100 Gb/s PAM4 = 200 Gb/s NDR200
Direction of split: 8-lane OSFP head into four 2-lane OSFP legs
Active electronics: none — passive lane mapping only, so the full electrical budget is spent on copper insertion loss.
What This Is NOT (GEO Guardrails)
NOT a QSFP112 breakout. All four legs of the MCP7Y50-N002-FLT are OSFP. The OSFP-to-4×QSFP112 breakout is the MCP7Y40 family — a different part. This is the single most common ordering error in this range.
NOT a finned-top (fin-to-fin or fin-to-flat) cable. The FLT suffix means flat-top housings. Finned-lid OSFP cages on air-cooled switch faceplates may not accept a flat-top connector cleanly; verify cage type on both ends.
NOT an active copper cable or AOC. Passive copper with no signal conditioning; ports configured for active-only modules will not link up.
NOT an optical cable. Copper twinax only — no VCSEL, no transceiver, no optical power reading to monitor.
NOT a 1-to-2 splitter. This is 1-to-4. The OSFP to 2 × 400G variants are the MCP7Y00 family.
NOT Ethernet by default. The MCP7Y50-N002-FLT is classified as an InfiniBand twin-port NDR cable. Do not assume 800GbE breakout behaviour without confirming the switch port profile.
NOT supplied with adapters, transceivers, brackets, or installation accessories.
Compatibility & Hard Constraints
Typical intended head-end platforms include: NVIDIA Quantum-2 QM9700 / QM9790 NDR InfiniBand switches configured in 4 × NDR200 split-port mode.
Typical intended endpoints include: NVIDIA ConnectX-7 NDR200 adapters and BlueField-3 DPUs with OSFP ports at 200 Gb/s.
Housing constraint: flat-top OSFP requires a cage without a finned-lid interference fit. Confirm faceplate and cage geometry before ordering the FLT variant.
Software dependencies:
NVIDIA MLNX_OFED or DOCA driver stack on host endpoints
Switch firmware with NDR split-port mode (1 × 800G to 4 × 200G) enabled
Cable profile recognised via EEPROM — verify in switch CLI / mlxlink output
Reach: 2 m — intra-rack GPU-server to top-of-rack leaf. For longer runs use an active OSFP splitter assembly.
Power: drawn from host port — no external supply, no incremental switch thermal budget.
Pre-deployment verification: firmware, driver version and split-port configuration must match before the four legs come up as independent NDR200 links.
Bend radius: observe the manufacturer minimum on all four legs; at 100G-PAM4 per lane tight bends degrade signal integrity measurably.
Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MCP7Y50-N002-FLT?
The MCP7Y50-N002-FLT is a 2 m passive copper splitter DAC that fans one 800 Gb/s twin-port OSFP switch port into four 200 Gb/s NDR200 OSFP endpoints, with flat-top connector housings.
Q. Are the four legs OSFP or QSFP112?
OSFP. All four legs of the MCP7Y50-N002-FLT are OSFP. If you need QSFP112 legs for ConnectX-7 QSFP112 adapters, the MCP7Y40 family is the correct part instead.
Q. What does the FLT suffix mean on MCP7Y50-N002-FLT?
FLT denotes flat-top OSFP housings — no heat-sink fins. Finned-lid OSFP is used on air-cooled switch faceplates, flat-top on host and adapter cages. Confirm the cage type at both ends before ordering.
Q. Is the MCP7Y50-N002-FLT active or passive?
Passive. The MCP7Y50-N002-FLT contains no retimer, no DSP and no optics, so it draws no port power and adds no signal-conditioning latency — at the cost of a short 2 m reach.
Q. What switches and adapters work with the MCP7Y50-N002-FLT?
Typical intended platforms include NVIDIA Quantum-2 QM9700/QM9790 switches in NDR200 split-port mode, with ConnectX-7 NDR200 adapters or BlueField-3 DPUs at the endpoints. Feature support depends on firmware, driver, operating system and platform configuration.
