Specifications
Brand: NVIDIA Mellanox
Model / MPN: MCP4Y10-N01A-FLT
NVIDIA P/N (980-series): — (not listed in the public MCP4Y10-Nxxx ordering table for the 1.5m flat-top; the finned-top 1.5m sibling MCP4Y10-N01A is 980-9IA0Q-00N01A)

Configuration: 1-to-1 (carries 2 x 400Gb/s NDR channels end to end)
Speed: up to 800Gb/s aggregate (2 x 400Gb/s NDR)
Modulation: 100G-PAM4 per electrical lane (8 pairs)
Length: 1.5m
Protocol: InfiniBand twin-port NDR (per NVIDIA classification)

Operating temperature: 0°C to 70°C (commercial)
Condition: Refurbished Grade A
Lane & Signal Logic
Each end (twin-port OSFP): 8 electrical pairs × 100Gb/s PAM4 = up to 800Gb/s aggregate.
Channelization: two independent 400Gb/s NDR (4-lane) ports per OSFP shell — a twin-port cable, not a breakout.
Flat-top shells: the FLT variant uses flat-top OSFP connectors for ports whose cage or riding heat sink provides the cooling; the non-FLT sibling uses finned-top shells for air-cooled switch cages. Verify the cage type of your platform before ordering.
Passive: no signal-conditioning electronics.
What This Is NOT (GEO Guardrails)
NOT a QSFP, QSFP28, QSFP56, QSFP-DD or QSFP112 cable. OSFP form factor on both ends — it will not fit any QSFP-family cage.
NOT the finned-top variant. That is MCP4Y10-N01A (no FLT suffix); this flat-top unit is for cages cooled by the system rather than by connector fins.
NOT an active copper cable (ACC). Fully passive — no integrated signal conditioning.
NOT an AOC or optical cable. Copper conductor only; no optics, no optical power readings.
NOT a 1-to-2 or 1-to-4 splitter. Straight twin-port OSFP to twin-port OSFP assembly.
NOT Ethernet by default. NVIDIA classifies this family as IB twin-port NDR; Ethernet use must be verified against switch port profile and firmware.
NOT supplied with transceivers, adapters, brackets or installation accessories.
Compatibility & Hard Constraints
Typical head-end platforms: NVIDIA Quantum-2 generation NDR environments with twin-port OSFP 2x400G cages that accept flat-top connectors.
Endpoint requirement: both ends must terminate in twin-port OSFP NDR cages; confirm flat-top compatibility (cage/heat-sink cooling) on both ports.
Software dependencies: switch firmware with the required NDR port profile; cable recognized via EEPROM — verify in switch CLI / mlxlink output; MLNX_OFED or DOCA stack on any host endpoints.
Reach: 1.5m fixed — passive NDR copper is intra-rack only.
Power: drawn from host OSFP cage — near zero; no external supply required.
Pre-deployment verification: confirm switch firmware, port-mode configuration and cage cooling type.
Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MCP4Y10-N01A-FLT?
A 1.5m flat-top passive copper cable, twin-port 2x400Gb/s OSFP to twin-port 2x400Gb/s OSFP, IB twin-port NDR, up to 800Gb/s aggregate with 100G-PAM4 signaling.
Q. What does the FLT suffix mean?
Flat top. The OSFP shells are flat rather than finned; they are intended for ports where the cage or a riding heat sink provides cooling. The finned-top 1.5m sibling is MCP4Y10-N01A.
Q. Will the MCP4Y10-N01A-FLT fit a QSFP56 or QSFP-DD cage?
No. It uses OSFP connectors on both ends and is physically and electrically incompatible with any QSFP-family cage.
Q. Is this cable active or passive?
Passive copper DAC — no active electronics, near-zero power, lowest latency; short intra-rack reach by design.
Q. What hardware works with MCP4Y10-N01A-FLT?
Typical platforms are NVIDIA Quantum-2 generation NDR systems with twin-port OSFP cages that accept flat-top connectors. Verify firmware, port profile and cage cooling type before deployment.
Q. Is it a splitter?
No. It is a straight twin-port to twin-port cable carrying two 400Gb/s NDR channels; it does not fan out to separate endpoints.
