## Summary description

Direct Attach Copper (DAC) cable CBO QSFP28-DAC-2M is a 2-meter passive copper interconnect compatible with Nokia QSFP28 ports. Designed for short-range high-speed links between switches, routers or servers, it provides a reliable physical connection for 100GbE QSFP28 interfaces. Suitable for data center top-of-rack, aggregation and server connectivity where a fixed, low-latency cable is needed.

## Long description

Direct Attach Copper (DAC) cable CBO QSFP28-DAC-2M is a 2-meter passive copper interconnect compatible with Nokia QSFP28 ports. It is engineered for short-range 100GbE links between switches, routers and servers, delivering a fixed, low-latency physical connection for QSFP28 interfaces in data center top-of-rack, aggregation and server environments. The cable supports the electrical signaling and form factor requirements of QSFP28 ports, enabling straightforward deployment without the need for separate transceivers.
Advantages
This 2 m passive DAC cable provides predictable performance for short-reach 100GbE connections, with low power consumption since no active optics or separate transceivers are required. Its direct-attach design reduces component count and simplifies cabling between compatible QSFP28 ports while offering low latency and stable link characteristics. The cable is designed to meet mechanical and electrical requirements of QSFP28 interfaces, ensuring reliable mating and signal integrity for typical data center topologies.
Suitable for
 Short-range 100GbE connections between QSFP28-equipped switches
 Server to switch links in top-of-rack deployments
 Aggregation and spine-leaf links within data center racks
 Temporary or permanent high-speed interconnects where low latency and fixed cabling are preferred
Key specifications
 Length: 2 meters
 Interface: QSFP28 electrical connector on both ends
 Data rate: designed for 100 Gigabit Ethernet (100GbE)
 Cable type: passive copper direct attach
 Typical use range: short-reach, within same rack or adjacent racks
 Power: passive (no additional power required for the cable itself)
How to use
Ensure both devices have compatible QSFP28 ports and that the link speed and configuration support direct attach copper cables. With devices powered off or following hot-plug guidelines from the equipment vendor, align the QSFP28 connectors and insert the cable until the latch engages. Configure the network interfaces according to your switch or server documentation, verify link status in the management interface, and test throughput and error counters to confirm proper operation. For removal, disengage the latch and withdraw the connector following vendor procedures.
Usage recommendations
Install the DAC cable in environments within recommended temperature and airflow limits of your networking equipment, keep cable bends above the minimum bend radius to preserve signal integrity, and avoid routing next to high-power electrical sources to reduce potential interference. Use this 2 m passive DAC for short, fixed links where low latency and minimal power draw are priorities.
