NVIDIA Mellanox MCP1600-E003E26 100Gb/s QSFP28 Passive Direct Attach Copper Cable – 3m, EDR InfiniBand, Low Latency, Near-Zero Power for Data Center Interconnects

Cost-effective 3-meter passive copper cable delivering 100Gb/s throughput for EDR InfiniBand and 100GbE applications—featuring near-zero power consumption, ultra-low latency, and robust signal integrity for short-reach data center interconnects.

• 100Gb/s aggregate bandwidth over 4x 25Gb/s NRZ lanes per direction
• 3-meter length with 26AWG conductors, black LSZH jacket
• Supports InfiniBand EDR (100Gb/s) and 100 Gigabit Ethernet
• Near-zero power consumption (<0.1W) | Bit Error Rate better than 1E-15
• Hot-pluggable QSFP28 form factor, SFF-8665 compliant, RoHS compliant

• 100Gb/s Throughput: Four 25Gb/s NRZ channels per direction, aggregate 100Gb/s full duplex.
• Passive Copper Design: No active components—lowest cost, zero latency, and virtually zero power draw.
• 26AWG Conductors: Optimized for 3-meter reach with excellent signal integrity.
• Protocol Agnostic: Supports InfiniBand EDR and 100GbE with auto-negotiation.
• Rigorous Testing: 100% production tested for BER <1E-15 with Mellanox systems.

The MCP1600-E003E26 complies with SFF-8665 (QSFP28 electrical) and SFF-8636 (management interface). It uses 4x 25Gb/s NRZ modulation over twinax copper pairs. Supports InfiniBand EDR (IBTA 1.3) and 100GBASE-CR4 Ethernet. Integrated EEPROM provides product identification via I²C. RoHS compliant with LSZH jacket.

As a passive direct attach copper cable, the MCP1600-E003E26 relies on high-quality 26AWG twisted pairs and precision impedance matching (100Ω differential) to transmit 25Gb/s NRZ signals up to 3 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, near-zero power link ideal for short-reach intra-rack connections.

• InfiniBand EDR Fabrics: Connect QM8700/QM8790 switches to ConnectX-5/6 adapters within racks.
• 100GbE Networks: Link Spectrum switches to servers or storage nodes up to 3m apart.
• Top-of-Rack to Server: Short-reach intra-rack connections with minimal power and cost.
• Storage Clusters: RDMA over Converged Ethernet (RoCE) and NVMe-oF deployments.

Note: Operating temperature 0°C to 70°C, storage -40°C to 85°C. Minimum single bend radius: 47mm (5x diameter). Repetitive/assembly bend radius: 94mm (10x diameter).

• vs. Active Optical Cables (AOC): Significantly lower cost, zero power consumption, and no cleaning required.
• vs. Active Copper (ACC): Lower cost and zero power—ideal for very short reaches ≤3m.
• Proven Reliability: BER better than 1E-15 with Mellanox systems ensures error-free transmission.
• Thicker 26AWG: Better signal integrity at 3m compared to 30AWG cables.

We offer 24/7 technical consultation, RMA services, and cabling infrastructure design support. Each MCP1600-E003E26 is backed by a 1-year limited hardware warranty and 100% factory testing. Our inventory ensures same-day dispatch for in-stock items. Pre-sales support for compatibility verification with ConnectX adapters and Quantum switches is available.

A: Yes, it is fully compatible with ConnectX-5 (EDR) and ConnectX-6 (EDR/HDR100) adapters.

A: Yes, it supports 100GBASE-CR4 Ethernet as well as InfiniBand EDR.

A: For single bend (far from connector), minimum is 47mm (5x diameter). For repeated or assembly bend near connector, maintain 94mm (10x diameter).

A: No, it is plug-and-play. The EEPROM provides identification, and the host automatically sets up the link.

A: Near-zero (<0.1W) as there are no active components.

• ESD Sensitivity: Use grounded wrist straps when inserting into QSFP cages. Connectors are shipped with protective caps—remove only immediately before installation.
• Bend Radius: Do not exceed minimum bend radius (47mm single, 94mm repetitive). Avoid sharp bends near connectors.
• Operating Temperature: Ensure ambient temperature within 0°C–70°C.
• Storage: Store in clean, dry environment between -40°C and 85°C.
• Compatibility: Verify connector type (QSFP28) matches your equipment.
