Product Features
Technical Overview
This direct attach cable operates at a full 40 Gbit/s data transfer rate, supporting 40GBase-CR4 and 4x10G Base-CU standards for seamless integration with compatible networking equipment. The passive design eliminates active electronics, reducing power consumption and potential points of failure while maintaining signal quality over short distances.
The QSFP+ connector on one end interfaces with 40GbE switches or adapters, while the four SFP+ connectors on the opposite end distribute the bandwidth across multiple 10GbE devices. This configuration is ideal for aggregating server connections or expanding switch port capacity without additional transceiver modules.
This section brings together practical product details such as Cable Type, Cable Length, Connector Type on First End, Product Material, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

User Manual
FAQ
What is the purpose of a QSFP+ to 4xSFP+ direct attach cable?
This cable allows a single 40GbE QSFP+ port to connect to four 10GbE SFP+ devices, enabling efficient breakout configurations. It's commonly used in data centers to aggregate server connections, expand switch capacity, or create high-density network links without requiring separate transceivers for each connection.
What does 'passive twinax' mean for this cable?
Passive twinax indicates the cable uses copper conductors without active signal amplification electronics. This design reduces power consumption, minimizes potential failure points, and maintains signal quality over short distances like the 1-meter length of this cable. It's ideal for reliable, low-latency connections within racks or adjacent equipment.
Is this cable compatible with non-Cisco networking equipment?
While designed for Cisco compatibility, this cable works with any networking device that supports the 40GBase-CR4 or 4x10G Base-CU standards and accepts QSFP+ and SFP+ connections. Always verify compatibility with your specific equipment model, as some systems may require vendor-coded modules for full functionality.
What are the advantages of TAA compliance for this product?
TAA compliance ensures the cable meets the Trade Agreements Act requirements for U.S. government procurement, confirming it's substantially manufactured in the United States or designated countries. This makes it suitable for federal, state, and educational institutions with strict sourcing regulations, while also indicating quality manufacturing standards.
How does the 1-meter length affect deployment scenarios?
The 1-meter length is optimized for within-rack connections, such as linking a top-of-rack switch to servers directly below it. This short distance maintains signal integrity in passive twinax designs while minimizing cable clutter. For longer runs beyond 3-5 meters, active optical cables or fiber transceivers would typically be recommended instead.
What warranty coverage does this direct attach cable include?
The cable comes with a 3-year lifetime warranty that covers manufacturing defects and ensures reliable performance throughout its service life. This warranty provides assurance for critical network infrastructure deployments where cable failures could disrupt operations, supporting long-term investment protection in data center environments.
