Product Overview
The Mellanox ® MCP1600-E003E26 is a high-performance, cost-effective QSFP28 direct attach copper (DAC) cable designed for 100Gb/s InfiniBand EDR and Ethernet applications. It provides a reliable, power-efficient alternative to optical fiber for short-reach interconnects within data centers and high-performance computing (HPC) environments.
This passive copper cable assembly integrates four high-speed copper pairs, each operating at up to 25 Gb/s, to deliver an aggregate data rate of 100 Gb/s. With no active components, it offers the lowest possible latency and near-zero power consumption, making it ideal for top-of-rack (ToR) and adjacent-rack connectivity.
Each QSFP28 connector includes an EEPROM that stores product identification and configuration data, which the host system can read via the SFF-8636 compliant I²C management interface. The cable is hot-pluggable, RoHS compliant, and features a durable LSZH (Low Smoke Zero Halogen) jacket.
Key Features
- Up to 100 Gb/s aggregate data rate
- SFF-8665 compliant QSFP28 form factor
- Passive design - no active components, zero additional power draw
- Single 3.3 V supply voltage
- Operating case temperature: 0°C to 70°C
- Hot-pluggable for easy installation and replacement
- RoHS compliant and LSZH jacket for safety
- SFF-8636 compliant I²C management interface
Technology & Construction
The MCP1600-E003E26 is a passive twinaxial copper cable assembly. It directly transmits electrical signals between QSFP28 ports without any signal conditioning, retiming, or amplification. This passive approach delivers several key advantages:
- Ultra-low latency: Sub-100 ns typical, critical for HPC and financial trading.
- Negligible power consumption: Consumes less than 0.1 W, reducing data center thermal load.
- High signal integrity: 100 Ω differential impedance and optimized shielding minimize crosstalk and insertion loss.
The cable construction uses 26 AWG copper conductors with a durable LSZH jacket. The thicker 26 AWG gauge supports longer reaches while maintaining signal integrity. Each cable is rigorously tested during production to ensure out-of-the-box performance and long-term durability, with a Bit Error Rate (BER) better than 1E-15 when used with Mellanox systems.
Compatibility
The MCP1600-E003E26 is fully compliant with industry standards and is interoperable with a wide range of networking equipment:
- Standards: SFF-8665 (QSFP28), SFF-8636 (management interface), IEEE 802.3bj (100GBASE-CR4), InfiniBand EDR
- Compatible with: NVIDIA® / Mellanox® switches, adapters, and systems; also interoperable with other MSA-compliant QSFP28 ports
- EEPROM: Programmed with product information per SFF-8636; vendor name: NVIDIA, OUI: 00-02-C9
Note: For best performance and compatibility, we recommend verifying compatibility with your specific switch or server model before ordering.

Frequently Asked Questions
Q: What is the maximum distance for a passive DAC cable?
A: Passive DACs are typically recommended for distances up to 5 meters. The MCP1600-E003E26 is 3 meters and provides optimal signal integrity within that range.
Q: Is this cable compatible with 100GbE switches from other vendors?
A: Yes, it is MSA-compliant and interoperates with most standard QSFP28 ports. However, we recommend verifying compatibility with your specific switch model.
Q: What does "passive" mean for this cable?
A: Passive means the cable has no active electronic components (amplifiers, retimers). It relies solely on copper conductors to transmit signals, offering the lowest possible latency and power consumption.
Q: What is the difference between 30 AWG and 26 AWG versions?
A: Lower AWG numbers indicate thicker conductors, which allow for longer cable lengths. The 30 AWG version is used for shorter cables (up to 2m), while 26 AWG supports longer reaches (up to 5m). The MCP1600-E003E26 uses 26 AWG for reliable 3-meter performance.
Precautions
- Bending radius: Minimum single bend radius is 5× the cable outer diameter (approx. 47 mm for 26 AWG); repetitive bending radius is 10× the outer diameter (approx. 94 mm).
- Connector handling: Avoid pulling on the connector housing; use the pull tab to disconnect.
- Operating temperature: Do not operate outside the 0°C to 70°C case temperature range.
- ESD precautions: Follow standard ESD handling procedures to prevent damage to sensitive components.
