## Summary description

CBO QSFP28-DAC-1M is a 1 m passive copper DAC cable with QSFP28 connectors at both ends, designed for high-speed 100Gbps direct-attach connections between QSFP28 ports. It provides a low-latency, power-efficient link for switches, routers and servers in data centers and rack-to-rack interconnects, offering a simple plug-and-play solution without the need for optical transceivers.

## Long description

CBO QSFP28-DAC-1M is a 1 m passive copper direct-attach cable with QSFP28 connectors on both ends, engineered for 100 Gbps point-to-point links. Designed for short-reach interconnects, the cable provides a low-latency and power-efficient connection between QSFP28 ports in switches, routers and servers. The passive construction eliminates the need for optical transceivers, offering a compact plug-and-play solution for data center and rack-to-rack connections.
Advantages
The passive copper design delivers reduced latency and lower power consumption compared with active optics or powered modules over the same short distances. A fixed 1 m length simplifies cable management in dense rack environments and minimizes signal loss for short interconnects. QSFP28 connectors at both ends ensure compatibility with standard 100 Gb/s QSFP28 ports and provide a reliable mechanical fit for high-density installation scenarios.
Suitable for
Short-reach 100 Gbps links between QSFP28 ports in switches and routers
Server-to-switch or switch-to-switch interconnects within a rack or adjacent racks
High-density data centre environments where low latency and low power are required
Environments that prefer plug-and-play copper solutions over optical transceivers
Key specifications
Connector type: QSFP28 to QSFP28
Cable type: passive copper direct-attach (DAC)
Nominal data rate: 100 Gbps
Length: 1 m
Form factor: QSFP28 direct-attach cable for short-reach interconnects
Typical applications: data center rack-to-rack and intra-rack connections
How to use
Install the CBO QSFP28-DAC-1M by inserting each QSFP28 connector into the corresponding QSFP28 ports on the devices to be linked. Ensure both ports support 100 Gbps operation and are powered down or follow hot-plug guidance from the equipment vendor if required. Once seated, verify link status in the host devices' management interface and confirm expected data rates and lane configurations. No optical transceivers or additional configuration is typically required for standard direct-attach operation.
Usage recommendations
Use the 1 m passive QSFP28 DAC for short, high-bandwidth connections within racks or between adjacent racks. Avoid bending the cable beyond manufacturer-recommended bend radii, and ensure connectors are kept free of dust and debris when not in use. For longer distances or when isolation from electrical interference is required, consider active optical solutions or fiber-based transceivers instead.
