Product Features
Technical Overview
This 40GbE direct attach cable utilizes twinaxial copper construction with 30 AWG wiring and 100 Ohm impedance for optimal signal transmission. The cable features male QSFP+ connectors on one end that split to four male SFP+ connectors, enabling connectivity between 40GbE and 10GbE devices within the same infrastructure.
The passive design requires no external power, reducing complexity and potential points of failure. The cable jacket is constructed from durable PVC material, providing protection against physical damage while maintaining flexibility for routing through racks and cable management systems.
This section brings together practical product details such as Cable Type, Cable Length, Connector Type on First End, Color Family, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
Key Product Advantages
This direct attach cable offers several advantages over traditional fiber optic solutions, including lower cost, reduced power consumption, and simplified deployment. The copper construction eliminates the need for separate transceivers at each end, providing a complete connectivity solution in a single cable assembly.
Compatibility Assurance
Works with MSA compliant switches from major manufacturers including Ubiquiti, D-Link, Netgear, Supermicro, and TP-Link that accept uncoded modules and transceivers.
- MSA uncoded compatible
- Won't void OEM support
- Tested with multiple switch platforms
Reliability & Support
Backed by StarTech.com's lifetime warranty on the cable itself, with access to technical advisors for installation guidance and troubleshooting support.
- Lifetime warranty
- Technical advisor access
- Factory termination quality
Deployment / Use Cases
This breakout cable is specifically designed for server room and data center environments where high-density connectivity between 40GbE and 10GbE devices is required. The 1-meter length makes it ideal for intra-rack connections between top-of-rack switches and servers, or between adjacent racks in the same row.
Common deployment scenarios include connecting 40GbE switch uplink ports to multiple 10GbE server ports, aggregating multiple 10GbE connections into a single 40GbE trunk, or creating high-bandwidth links between storage arrays and compute nodes. The cable's black color and professional finish integrate seamlessly with standard data center aesthetics.
Physical Profile
The cable features a standard black PVC jacket that provides durability and flexibility for routing through cable management systems. With a weight of 8.40 ounces (238 grams), the cable is lightweight enough for easy installation without adding significant load to cable trays or management arms. The compact connector design allows for high-density port utilization in switch and server chassis.

FAQ
What type of devices is this cable compatible with?
This direct attach cable is compatible with MSA compliant network devices, servers, switches, transceivers, and routers that accept uncoded QSFP+ and SFP+ modules. It has been verified to work with switch models from manufacturers including Ubiquiti, D-Link, Netgear, Supermicro, and TP-Link when they are configured to accept uncoded transceivers.
What is the difference between this DAC and fiber optic cabling?
This direct attach cable uses twinaxial copper construction instead of fiber optic strands, making it a more cost-effective solution for short-distance connections (up to several meters). Unlike fiber optic solutions that require separate transceivers at each end, this DAC integrates the connectors directly into the cable assembly, reducing component count and potential points of failure while maintaining 40 Gbps performance.
Can this cable be hot-swapped during operation?
Yes, this cable features hot-swappable connectors that allow for installation, removal, or replacement without powering down the connected equipment. This capability is essential for maintaining network uptime in production environments where scheduled downtime may not be available for maintenance activities.
What does 'MSA uncoded compatible' mean for this cable?
MSA (Multi-Source Agreement) uncoded compatibility means this cable follows the industry-standard specifications for direct attach cables without manufacturer-specific coding. This ensures broad compatibility with networking equipment from multiple vendors that adhere to the same MSA standards, providing flexibility in mixed-vendor environments and avoiding vendor lock-in scenarios.
What warranty coverage does this cable include?
StarTech.com provides a lifetime warranty on this direct attach cable, covering the cable itself for as long as you own it. The warranty is specific to the cable assembly and does not affect your equipment's OEM support. Additionally, technical support is available from StarTech.com's advisor team for installation guidance and troubleshooting assistance.
Is this cable suitable for data center environments?
Yes, this cable is specifically designed for server room and data center deployment. The 1-meter length is ideal for connections within racks or between adjacent racks, the black PVC jacket provides a professional appearance, and the passive copper construction offers reliable performance without the complexity of active components. The cable is RoHS and WEEE compliant for environmental responsibility in regulated environments.
