## Summary description

Direct-attach copper (DAC) cable CBO QSFP28-DAC-5M is a 5-meter QSFP28-compatible assembly designed for short-reach 100GbE or InfiniBand connections. Compatible with Infinera QSFP28 ports, it provides a cost-effective, low-latency link for switches, routers and servers in data centers and network racks. Suitable for high-density cabling where power efficiency and reliable electrical performance are required.

## Long description

Direct-attach copper (DAC) cable CBO QSFP28-DAC-5M is a 5-meter QSFP28-compatible assembly for short-reach 100 Gigabit Ethernet or InfiniBand links. Designed to mate with Infinera-compatible QSFP28 ports, this cable offers a low-latency, energy-efficient copper connection for switches, routers and servers in data centers and network racks. The 5 m length supports typical top-of-rack and row-level interconnects where reliable electrical performance and compact cabling are required.
Advantages
This DAC cable delivers predictable electrical characteristics and low latency typical of direct-attach copper solutions while avoiding the complexity of optical transceivers. It reduces power consumption compared with active optical solutions and enables high-density deployments thanks to compact QSFP28 connectors and a flexible jacket. The assembly is suitable for environments that require stable 100GbE or InfiniBand throughput with minimal configuration and straightforward physical installation.
Suitable for
 Short-reach 100GbE connections between switches and leaf/spine devices
 Server-to-switch links in high-density racks
 InfiniBand HDR or EDR links in clustered compute environments
 Top-of-rack and row-level cabling where a 5 m copper link is optimal
Key specifications
 Connector type: QSFP28-compatible twinax copper
 Length: 5 meters
 Supported data rates: up to 100 Gbps line rate
 Cable type: direct-attach copper (passive or active depend on model; verify compatibility)
 Expected latency: low, suitable for latency-sensitive applications
 Form factor: QSFP28 plug-and-play assembly for QSFP28 ports
How to use
Insert each QSFP28 connector into the appropriate QSFP28 port on your network devices until the latch engages. Ensure devices are powered and that port configurations match the intended 100GbE or InfiniBand link settings. Verify link status via your switch or server management interface and confirm correct speed and lane negotiation. For best performance, route the cable to avoid sharp bends and maintain recommended bend radius. If a model with active components is used, verify that connected equipment supports active/passive DAC operation as required.
Usage recommendations
Use this 5 m QSFP28 DAC for short interconnects in data centers where low latency, power efficiency and predictable electrical performance are priorities. Confirm compatibility with your Infinera-compatible QSFP28 ports and verify device firmware or vendor compatibility lists when deploying at scale.
