StarTech.com J9281BST 1m 10G SFP+ to SFP+ Passive Direct Attach Copper Twinax Cable for HPE

The StarTech.com J9281BST is a high-performance 1-meter 10G SFP+ to SFP+ passive direct attach copper (DAC) twinax cable, specifically engineered to be fully compatible with HPE networking equipment. This cable provides a reliable and efficient solution for high-speed data transmission, supporting 10 Gbps Ethernet applications. By utilizing copper twinax technology, it offers a low-latency and low-power alternative to traditional fiber-optic cabling for short-range connectivity needs within data centers and enterprise server rooms.

Advantages

This direct attach cable is designed for seamless integration with HPE switches and routers, ensuring consistent performance that meets or exceeds OEM specifications. Its passive design ensures minimal power consumption and low latency, which is critical for high-speed networking environments. The hot-swappable nature of the cable allows for quick and easy installation or replacement without the need to power down network equipment, thereby reducing downtime. Furthermore, the cable is built with high-quality materials, including a durable PVC jacket and 30 AWG wire, ensuring long-term reliability and signal integrity for your network infrastructure.

Suitable for

• Short-range rack-to-rack network connections
• Switch-to-server data links
• High-speed 10GbE enterprise network environments
• Data center infrastructure upgrades

This cable may not be suitable for long-distance networking applications, as passive DAC cables are limited to short reaches, typically within a single rack or adjacent racks. It is also not intended for use in environments requiring fiber-optic isolation or where cable runs exceed the physical length limitations of copper-based twinax technology.

Key specifications

• Length: 1 meter
• Data rate: 10 Gbps
• Connector type: SFP+ to SFP+
• Cable type: Passive Twinax Copper
• Impedance: 100 Ohm
• Wire gauge: 30 AWG
• Jacket material: Polyvinyl chloride (PVC)
• Compatibility: MSA compliant and HPE compatible

To use this cable, simply insert the SFP+ connector into the corresponding SFP+ port on your network switch, router, or server. The cable is hot-swappable, meaning it can be plugged in while the equipment is running. Ensure that the cable is securely seated in the port until you hear a click or feel it lock into place. No additional configuration is typically required, as the cable is designed to be recognized automatically by compatible hardware.

What to consider before purchase

• Verify that your network equipment supports SFP+ ports
• Ensure the 1-meter length is sufficient for your specific rack layout
• Confirm that your hardware accepts uncoded or MSA-compliant modules

For optimal network performance, ensure that the cable is not bent beyond its minimum bend radius and is kept away from sources of high electromagnetic interference. Regularly inspect the connectors for dust or debris to maintain a clean signal path.
