Cabo Direct Attach CBO SFP+ SFP-10G-DAC-0.5M-ZY 0,5 m SFP+ DAC passivo

Direct Attach Cable CBO SFP+ SFP-10G-DAC-0.5M-ZY is a 0.5 metre passive SFP+ twinax cable designed for 10 Gigabit Ethernet connections. The fixed cable assembly features SFP+ form-factor connectors on both ends for direct attachment between compatible SFP+ ports on switches, servers and storage devices. As a copper direct attach solution, it provides low latency and reduced power consumption compared with optical transceivers and separate fiber patch cords, making it suitable for short-reach interconnects inside racks or between adjacent racks.

Advantages

The passive SFP+ DAC offers a compact, ready-to-use connection without the need for separate transceivers, reducing component count and simplifying installation. Its short 0.5 m length minimises cable slack and improves airflow in dense rack environments. The copper twinax construction delivers low latency and energy-efficient operation for 10GbE links, and the standardized SFP+ connectors ensure compatibility with a wide range of network equipment that supports direct-attach SFP+ modules.

Suitable for

• Short-reach 10 Gigabit Ethernet links inside server racks
• Direct connections between adjacent switches and top-of-rack devices
• High-density rack deployments where compact cabling is required
• Storage network interconnects and server-to-switch links

Key specifications

• Connector type: SFP+ on both ends
• Cable type: passive twinax copper
• Length: 0.5 m
• Supported data rate: 10 Gigabit Ethernet
• Application: short-reach, direct-attach interconnects within racks

How to use

Insert each SFP+ connector into compatible SFP+ ports on the devices you intend to connect, ensuring the latch engages and the module is fully seated. No additional transceivers or optical modules are required. Verify link status on both devices and configure network settings as needed for 10GbE operation. For best performance, avoid sharp bends and excessive pulling on the cable during installation.

Recommendations

Use the cable for short-distance connections (within the same rack or adjacent racks) and avoid deploying it for runs exceeding the recommended length. Ensure both endpoints support passive SFP+ DAC modules and check device compatibility lists when available. For higher port-to-port distances or where isolation is required, consider optical transceivers and fiber cabling instead.
