DAC cable CBO QSFP28-DAC-5M 5m compatible with NetApp QSFP28 direct-attach copper

CBO QSFP28-DAC-5M is a 5-meter direct-attach copper (DAC) cable designed for short-reach 100GbE connections and compatible with NetApp QSFP28 ports. The cable links QSFP28 devices such as switches, servers and storage within racks or between adjacent racks to enable high-throughput, low-latency communication. Its passive copper construction supports energy-efficient operation and plug-and-play installation, making it suitable for constrained data center topologies and enterprise environments that require reliable, high-speed intra-rack or top-of-rack connectivity.

Advantages

The CBO QSFP28-DAC-5M delivers high bandwidth for 100 Gigabit Ethernet connections while keeping latency and power consumption low compared to active optical or longer copper solutions. Its fixed 5 m length simplifies cable management for short interconnects, and the direct-attach QSFP28-to-QSFP28 form factor eliminates the need for separate transceivers, reducing component count and simplifying replacement. Compatibility with NetApp QSFP28 ports ensures straightforward interoperability in systems that use that interface standard.

Suitable for

• Short-reach 100GbE connections inside server racks
• Interconnects between adjacent switches or top-of-rack switching
• Direct server-to-storage links in data center environments
• Environments that prioritize low latency and low power usage

Key specifications

• Connector type: QSFP28 to QSFP28 direct-attach copper
• Length: 5 meters
• Supported data rate: 100 Gigabit Ethernet
• Cable type: Twinax / copper DAC, passive
• Typical use case: Short-reach intra-rack or adjacent-rack interconnects
• Form factor: Quad Small Form-factor Pluggable (QSFP28)

How to use

Install the cable by inserting each QSFP28 connector into the corresponding port on compatible devices until the latch engages. Ensure both endpoints support QSFP28 100GbE operation and that network ports are powered and configured according to your switch or server firmware requirements. No separate transceiver or external power source is required for passive operation. For best results, route the cable to avoid tight bends and excessive strain on the connectors.

Usage recommendations

Verify compatibility with the specific firmware and hardware revision of your NetApp or other QSFP28-enabled devices before deployment. Maintain bend radius and connector cleanliness to ensure signal integrity; avoid kinking or crushing the cable and use proper cable management to minimize electromagnetic interference and mechanical stress.
