## Summary description

CBO QSFP28-DAC-2M is a 2 meter direct-attach copper (DAC) cable compatible with QSFP28 ports and designed for 100Gbps short-range connectivity. It provides a low-latency, energy-efficient connection between switches, routers or servers in data centers and rack environments. Ideal for cost-effective, high-bandwidth interconnects where fiber is unnecessary.

## Long description

CBO QSFP28-DAC-2M is a 2 meter direct-attach copper (DAC) cable engineered for QSFP28 ports to deliver reliable 100Gbps short-range connectivity. Designed for use in data centre topologies and rack-to-rack links, the cable offers a compact, low-latency connection between switches, routers and servers where fibre optics are not required. The construction balances signal integrity and power efficiency for demanding high-bandwidth interconnects over short distances.
Advantages
The DAC cable provides a cost-effective alternative to optical transceivers and fibre assemblies for short reach connections, with low power consumption and minimal signal latency. Its pre-terminated QSFP28 connectors simplify installation and eliminate the need for separate transceivers, while the 2 m length fits typical rack and cabinet layouts. The copper assembly offers mechanical robustness and consistent electrical performance suitable for dense networking environments.
Suitable for
 100Gbps switch-to-switch connections within the same rack or adjacent racks
 Server-to-switch links in data centres requiring short, high-bandwidth interconnects
 Router interconnects in wiring closets and equipment rooms where fibre is unnecessary
 High-density top-of-rack deployments with QSFP28 ports
Key specifications
 Connector type: QSFP28 direct-attach copper (pre-terminated)
 Rated data rate: 100 Gbps
 Cable length: 2 metres
 Media: copper twinax cable for short-reach links
 Typical use case: short-range, rack-to-rack or intra-rack connectivity
 Latency: low, hardware-level direct connection
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on network equipment, ensuring proper orientation and secure latch engagement. No separate optical transceivers or patch panels are required; the cable is pre-terminated for plug-and-play installation. Verify port settings and link status on connected devices and confirm 100Gbps link negotiation. For best results, route the cable to avoid sharp bends, excessive tension, and sources of electromagnetic interference.
Usage recommendations
Use this direct-attach copper cable for short-distance connections up to 2 m inside racks or between adjacent racks. Avoid running the cable near high-power electrical equipment and maintain minimum bend radius specified by the vendor to preserve signal integrity and mechanical life.
