## Long description

CBO QSFP28-DAC-3M is a 3-meter QSFP28 direct-attach copper (DAC) cable compatible with Nokia equipment. It is designed to provide a reliable, low-latency 100GbE wired connection between QSFP28 ports for short-reach links in data centers and enterprise networks. The cable offers a plug-and-play copper solution for rack-to-rack or intra-rack connections, supporting high-throughput traffic between switches, routers and servers while keeping power consumption and heat generation low.
Advantages
The QSFP28 direct-attach copper design delivers stable 100GbE performance with minimal latency and reduced power draw compared with active optical options at short distances. Its 3 m length is suitable for common rack and aisle layouts, eliminating the need for transceivers and minimizing installation time. The cable is built for compatibility with Nokia QSFP28 ports and provides a durable, low-maintenance physical link that simplifies cabling and reduces total cost of ownership for short-range interconnects.
Suitable for
 100 Gigabit Ethernet links between QSFP28 ports in switches and routers
 Rack-to-rack or intra-rack connectivity in data centers
 Short-reach server-to-switch connections
 High-density top-of-rack deployments requiring cost-effective copper links
Key specifications
 Connector type: QSFP28 direct-attach copper
 Supported data rate: 100GbE
 Cable length: 3 m
 Media: passive copper twinax
 Application: short-reach intra-rack and rack-to-rack interconnects
 Latency: low, suitable for high-throughput environments
How to use
Plug the QSFP28 connectors into the corresponding QSFP28 ports on compatible Nokia switches, routers or servers. Ensure the ports are powered down or follow the host equipment hot-plug guidelines where applicable before insertion or removal. Verify the link status via the host device management interface to confirm a successful 100GbE connection. For best results, route the cable to avoid sharp bends and mechanical strain, and secure it to prevent movement in high-traffic rack environments.
Usage recommendations
Use this 3 m QSFP28 DAC for short-distance connections within racks or between adjacent racks to achieve cost-effective, low-latency 100GbE links. Avoid exceeding bend radius limits and protect connectors from contamination; store unused cables in protective packaging to maintain connector integrity.
