Product Description
Mellanox MCP1600-E003E26 100Gb/s QSFP28 Passive DAC Cable
3m Passive Copper Cable • 26 AWG • EDR InfiniBand • 100Gbps
Reliable, cost-effective short-reach interconnect for 100Gb/s EDR InfiniBand and Ethernet applications. Hot-pluggable QSFP28 form factor, low power (<0.1W), and robust signal integrity for data center and high-performance computing environments.
Product Overview
The Mellanox MCP1600-E003E26 is a 100Gb/s QSFP28 passive direct attach copper (DAC) cable designed for high-density, low-latency interconnects. It features four high-speed copper pairs operating at 25Gb/s per lane, delivering aggregate 100Gb/s bandwidth. This 3-meter cable uses 26 AWG gauge and is terminated with industry-standard QSFP28 connectors. It is fully compliant with SFF-8665 and SFF-8636, ensuring seamless interoperability with Mellanox switches, adapters, and other QSFP28-enabled systems. The LSZH (Low Smoke Zero Halogen) jacket and RoHS compliance make it suitable for enterprise and green data center deployments.
Key Features
- 100Gb/s aggregate data rate (4 × 25Gb/s)
- QSFP28 form factor, SFF-8665 compliant
- Passive copper - zero power consumption for signal conditioning
- 3.3V single supply voltage (Vcc 3.135-3.465V)
- Operating case temperature 0°C to 70°C
- Bit Error Rate (BER) < 1E-15 with Mellanox systems
- Hot-pluggable, I²C management via SFF-8636
- LSZH jacket, RoHS compliant, lead-free & halogen-free PCB
- Rigorous production testing for out-of-box reliability
- 1-year limited hardware warranty
Technology & Signal Integrity
Mellanox passive copper cables utilize precision twin-ax copper construction with optimized impedance control (100Ω nominal) to minimize signal reflection and crosstalk. Each lane is independently shielded, and the overall cable is jacketed with LSZH material to reduce smoke and toxic emissions in case of fire. The MCP1600 series is characterized for propagation delay (4.5 ns/m typical) and maintains excellent return loss and insertion loss performance across the 0-70°C operating range. The integrated EEPROM stores cable attributes and product information, enabling host systems to automatically configure parameters for optimal link performance.
Typical Deployments
- High-Performance Computing (HPC): Connect InfiniBand EDR switches to compute nodes, storage systems, and GPU clusters.
- Data Center Leaf-Spine: Short reach top-of-rack (ToR) to spine switch interconnects in 100G Ethernet fabrics.
- Enterprise Core Networking: Reliable backbone links within or between adjacent racks in enterprise data centers.
- Test & Development Labs: Cost-effective, low-power links for prototyping and performance validation.
Compatibility
The MCP1600-E003E26 is compatible with any QSFP28/100G port that adheres to SFF-8665 and SFF-8636 standards. It is validated with Mellanox Spectrum™ and Quantum™ switches, ConnectX® adapters, and BlueField® DPUs. It also works with third-party switches and servers equipped with QSFP28 cages, provided the host supports passive copper DACs. For optimum BER performance, Mellanox recommends using this cable within Mellanox end-to-end systems.
