Product Description
NVIDIA MCP4Y10-N002 800Gb/s Twin-Port OSFP Passive DAC Cable
Cost-effective, near-zero power, 2-meter passive copper cable for 800Gb/s InfiniBand NDR and 400G Ethernet—delivering twin-port OSFP to 2x OSFP breakout connectivity with ultra-low latency.
- 800Gb/s twin-port OSFP to 2x400Gb/s OSFP passive direct attach copper (DAC)
- Based on 8 channels of 100G-PAM4 modulation per end
- 2-meter length using 26AWG conductors for optimal signal integrity
- Near-zero power consumption (<0.1W) | Operating case temperature 0°C to +70°C
- Hot-pluggable, RoHS compliant, LSZH jacket, SFF-8636 CMIS 5.0 compliant
Characteristics
- 800Gb/s Throughput: Twin-port OSFP design supporting full NDR InfiniBand or 400G Ethernet (2x400G breakout).
- Passive Copper Simplicity: No active components—lowest cost, zero latency, and virtually zero power draw.
- Protocol Agnostic: Firmware auto-detects InfiniBand or Ethernet; works with Quantum-2 and Spectrum-4 switches.
- Tuned Signal Integrity: Engineered for 100G-PAM4 with internal noise and reflection optimization.
- Rigorous Production Testing: Ensures out-of-box reliability and performance.
Technology & Standards
The MCP4Y10-N002 is compliant with OSFP MSA Rev. 1.12 and uses 8 channels of 100G-PAM4 modulation. It meets SFF-8665 and CMIS 5.0 specifications. The EEPROM provides product identification via I²C (SFF-8636). Supports both InfiniBand NDR and 400GbE with auto-protocol detection. Compliant with RoHS, LSZH, and HF (halogen-free) PCB requirements.
Working Principle: Passive Copper Transmission
As a passive direct attach copper cable, the MCP4Y10-N002 relies on high-quality 26AWG twisted pairs and precision impedance matching (100Ω differential) to transmit 100G-PAM4 signals up to 2 meters without active amplification. The cable's construction minimizes skew and crosstalk, while the EEPROM provides host devices with configuration data (length, vendor, equalization hints). The result is a zero-latency, zero-power link ideal for short-reach intra-rack connections.
Applications & Deployment
- Quantum-2 Switch to Switch: Connect two 800Gb/s InfiniBand switches up to 2m apart.
- Switch to DGX H100: Ideal for linking Quantum-2 ToR switches to NVIDIA DGX H100 systems (flat-top variants available).
- Ethernet Data Centers: Spectrum-4 400G switch interconnection or server-to-leaf.
- High-Density Racks: Short-reach intra-rack cabling with minimal power and cost.
Technical Specifications & Ordering Options
| Model | Length | AWG | Data Rate | Power per End | Cable Diameter | Min Bend Radius (single) |
|---|---|---|---|---|---|---|
| MCP4Y10-N002 | 2 m | 26 AWG | 800Gb/s (2x400G) | < 0.1 W | 8.9 ±0.3 mm | 44.5 mm (5x dia) |
| MCP4Y10-N00A | 0.5 m | 30 AWG | 800Gb/s (2x400G) | < 0.1 W | 7.2 ±0.3 mm | 36.0 mm |
| MCP4Y10-N001 | 1 m | 30 AWG | 800Gb/s (2x400G) | < 0.1 W | 7.2 ±0.3 mm | 36.0 mm |
Note: Flat-top variants available for DGX H100 (MCP4Y10-N00A-FLT, MCP4Y10-N001-FLT). All cables support operating temperature 0°C to +70°C, 3.3V supply, and include I²C serial interface with CMIS 5.0 memory map.
Advantages & Differentiators
- vs. Active Copper (ACC): Lower cost and zero power consumption (no equalizer IC). Ideal for very short reaches ≤2m.
- vs. Active Optical (AOC): Dramatically lower cost, zero latency, and no cleaning or optical alignment.
- Protocol Flexibility: Single SKU works for both InfiniBand and Ethernet; auto-detects protocol.
- Tuned Signal Integrity: Engineered for NDR’s demanding 100G-PAM4 with minimal reflections.

Frequently Asked Questions (FAQ)
Q: Can I use MCP4Y10-N002 with 400G Ethernet switches?
A: Yes. The cable auto-detects the protocol; when connected to a Spectrum-4 400G switch, it operates as 2x400GbE breakout. For InfiniBand Quantum-2, it runs as 800Gb/s twin-port NDR.
Q: What is the difference between passive DAC and ACC?
A: Passive DAC (like MCP4Y10) has no active components—lowest cost and zero power. ACC includes an equalizer IC to extend reach to 5m but consumes ~1.5W per end. For ≤2m, passive is optimal.
Q: Does this cable require any configuration?
A: No. It is plug-and-play. The EEPROM provides identification, and the host automatically sets up the link according to the protocol.
Q: What is the minimum bend radius for installation?
A: For the 2m model (26AWG), the single bend radius is 44.5 mm (5x diameter). For repeated bending, maintain 89 mm (10x diameter). Avoid sharp bends near the connector (assembly bend radius 10x diameter).
Q: Is this cable compatible with DGX H100 systems?
A: Yes. For DGX H100, we recommend the flat-top variants (MCP4Y10-N00A-FLT / -N001-FLT) which are designed for the specific chassis interface. The standard N002 works for switch-to-switch connections.
Precautions & Handling Guidelines
- ESD Sensitivity: Use grounded wrist straps when inserting into OSFP cages. Connectors are shipped with protective caps—remove only immediately before installation.
- Bend Radius: Never bend the cable tighter than 5x outer diameter (44.5mm for N002) during installation; maintain 10x for repeated flex.
- Operating Temperature: Ensure ambient temperature within 0°C–70°C.
- Compliance: This is a Class A device. In residential areas it may cause interference—install in shielded commercial environments.
- Storage: Store in clean, dry environment between -40°C and 85°C. Avoid crushing or heavy loads on cable.
