DAC-kabel CBO SFP28-DAC-2M 2 m passief koper SFP28 naar SFP28

CBO SFP28-DAC-2M is a 2 meter passive copper DAC cable with SFP28 connectors at both ends. It is engineered for short-reach, high-speed connections between SFP28 ports on switches, servers or storage devices, providing a direct-attach link that eliminates the need for separate transceivers. The cable supports 25 Gigabit Ethernet interconnects and is intended as a compact, power-efficient and cost-effective cabling option for data center and rack-level connectivity.

Advantages

The passive copper design reduces power consumption compared with active optical links and removes the expense of additional transceivers. With integrated SFP28 connectors, the cable delivers low latency and stable electrical performance for short-distance links. Its fixed 2 m length simplifies rack planning and minimizes cable clutter while offering a reliable direct connection between compatible SFP28 ports.

Suitable for

• Direct connections between SFP28 ports on network switches
• Server-to-switch or server-to-storage links within racks
• Short-range 25GbE aggregation and top-of-rack deployments
• Environments where low power and reduced hardware costs are priorities

Key specifications

• Connector type: SFP28 to SFP28
• Cable type: Passive copper direct attach
• Length: 2 meters
• Supported data rate: 25 Gigabit Ethernet
• Form factor: Direct-attach cable for rack-level interconnects
• Typical use: Short-reach electrical link (within a rack or adjacent racks)

How to use

Insert each SFP28 connector into the corresponding SFP28 port until it clicks into place, ensuring the link LEDs on both devices indicate a successful connection. No additional configuration is generally required beyond verifying link speed and port settings on connected devices. For reliable operation, route the cable to avoid sharp bends and mechanical stress near the connector ends, and verify that the connected ports are compatible with passive DAC cables.

Recommendations

Use the cable for short-distance 25GbE links within the same rack or between adjacent racks and avoid exceeding the specified 2 m routing length. Confirm device compatibility with passive SFP28 DACs in device documentation and handle connectors by the housing to prevent damage to the contacts.
