## Summary description

Passive Direct Attach Copper (DAC) cable CBO QSFP28-DAC-1M is a 1-meter QSFP28 copper interconnect supporting 100Gbps links. Designed for short-reach connections between QSFP28 ports in switches, routers and servers, it provides low-latency, power-efficient connectivity without transceivers. Ideal for data centers and rack-to-rack links where a fixed 1 m passive copper solution is required.

## Long description

Passive Direct Attach Copper (DAC) cable CBO QSFP28-DAC-1M is a 1-meter QSFP28 copper interconnect engineered for 100Gbps links. It connects QSFP28 ports directly between switches, routers and servers without optical transceivers, offering a compact, low-latency and power-efficient physical layer solution for short-reach environments such as data center top-of-rack and rack-to-rack connections.
Advantages
This passive copper cable provides a fixed-length, plug-and-play connection that eliminates the need for separate transceivers, reducing component count and simplifying inventory. The QSFP28 form factor supports 100Gbps throughput with minimal latency and low power consumption compared with active or optical solutions for short distances. Its 1 m length is optimized for dense rack layouts, offering reliable electrical performance and straightforward installation.
Suitable for
Short-reach 100Gbps links between switches in the same rack or adjacent racks
Direct server-to-switch connections where QSFP28 ports are available
High-density data center environments requiring low-latency, power-efficient interconnects
Key specifications
Connector type: QSFP28 to QSFP28 copper direct attach
Length: 1 meter
Data rate: up to 100 Gbps
Transmission medium: passive copper twinax cable
Latency: minimal electrical latency suitable for short links
Power: passive design with no additional power draw for transceiver modules
How to use
Insert each QSFP28 connector into the corresponding port on the network devices until the latch clicks into place. Ensure both devices are powered and configured to enable the 100Gbps link; link negotiation typically completes automatically. For best results, route the cable to avoid sharp bends and mechanical strain on connectors. If link status LEDs do not indicate a connection, verify port configuration and compatibility with the device vendor’s QSFP28 specifications.
Usage recommendations
Use this 1 m passive QSFP28 DAC cable for short intra-rack and adjacent-rack connections where a fixed-length, low-power 100Gbps link is required. Avoid exceeding recommended bend radii, keep connectors free of dust, and store unused cables in a clean, dry place to maintain signal integrity and connector reliability.
