## Summary description

CBO QSFP28-DAC-2M is a 2-meter direct-attach copper (DAC) cable compatible with QSFP28 ports and designed for NetApp systems. It provides a low-latency, cost-effective connection for 100GbE short-reach links between switches, servers or storage devices. Ideal for data center top-of-rack and aggregation layers where reliable, high-speed interconnects are required.

## Long description

CBO QSFP28-DAC-2M is a 2-meter direct-attach copper (DAC) cable designed for QSFP28 ports and validated for use with NetApp systems. It delivers a straightforward, low-latency physical link for 100 Gigabit Ethernet short-reach connections between switches, servers and storage devices. The cable's fixed QSFP28-to-QSFP28 connectors and copper construction remove the need for transceivers, making it a compact and cost-effective option for dense rack environments and top-of-rack aggregation.
Advantages
This DAC cable offers predictable electrical performance for 100GbE links with minimal protocol overhead and low latency. As a passive copper twinax assembly, it reduces system power consumption compared with active optics and simplifies installation by eliminating separate SFP/QSFP transceivers. The 2 m length balances flexibility and signal integrity for short interconnects, while compatibility with NetApp QSFP28 ports helps ensure interoperability in mixed-vendor data center deployments.
Suitable for
Short-reach 100GbE connections between top-of-rack switches and aggregation switches
Interconnects between servers and storage arrays in data center racks
High-density patching where low latency and low power are required
Environments preferring direct-attach copper over optical transceivers for cost or power reasons
Key specifications
Connector type: QSFP28 to QSFP28
Cable type: Direct-attach copper (twinax)
Supported link speed: 100 Gigabit Ethernet (100GbE)
Length: 2 meters
Latency: low, suitable for short-reach high-speed links
Power consumption: passive copper (no external power for transceivers)
Construction: fixed assembly optimized for rack density
How to use
Install the CBO QSFP28-DAC-2M by inserting each QSFP28 connector into the corresponding QSFP28 port on the network devices until the latch engages. Ensure both devices are powered and that port settings match the intended 100GbE link configuration. No additional transceivers or fiber patching is required; treat the cable as a direct physical link. For link diagnostics, use the host device firmware or management software to verify link status and speed after connection.
Usage recommendations
Route the cable to avoid sharp bends and maintain the minimum bend radius specified by the manufacturer to preserve signal integrity. Use this 2 m DAC for short interconnect distances inside racks or between adjacent racks; for longer spans or when optical isolation is needed, select appropriate fiber solutions. Verify firmware and port compatibility on NetApp and other vendor equipment before deployment to ensure seamless operation.
