## Summary description

CBO QSFP28-DAC-1M is a 1-meter passive copper DAC cable for 100G QSFP28 ports. Designed for short-reach connections between switches, routers or servers, it provides low-latency, cost-effective direct attach linking without transceivers. Suitable for data center top-of-rack and server interconnects where a reliable, fixed 1 m copper connection is required.

## Long description

CBO QSFP28-DAC-1M is a 1 metre passive copper direct attach cable (DAC) designed for 100G QSFP28 ports. It provides a fixed, low-latency electrical link between compatible switches, routers and server NICs without the need for separate optical transceivers, making it suitable for short-reach interconnects in data centre top-of-rack and server environments. The cable is intended for reliable, high-bandwidth connections where a 1 m passive copper solution is appropriate.
Advantages
The DAC cable offers a cost-efficient alternative to optical modules by integrating connector and cable in a single unit, reducing component count and power consumption. Its passive copper design delivers low latency and consistent signal performance over short distances, simplifying deployment and lowering operational overhead. The fixed length and integrated QSFP28 connectors eliminate the need for transceiver compatibility checks and spare optical module management.
Suitable for
Short-reach 100G links between top-of-rack switches
Server-to-switch connections in data centres
High-density patching in network racks where 1 m cable length is required
Low-latency connections for storage and compute clusters
Key specifications
Interface type: QSFP28 to QSFP28 electrical direct attach
Supported data rate: 100 Gigabit Ethernet
Cable type: Passive copper twinax
Length: 1 metre
Usage environment: Short-reach, within-rack or adjacent-rack interconnects
Thermal and mechanical: designed for rack and chassis installations (industrial operating ranges depend on host devices)
How to use
Install the DAC cable by aligning each QSFP28 plug with the corresponding port on the network devices and insert until the connector latches. Ensure both devices support QSFP28 electrical DAC connections and are configured for 100G operation. Avoid sharp bends or excessive strain on the cable; route the cable within the rack using appropriate cable management to prevent mechanical stress. For removal, depress the connector latch and withdraw the plug straight out to avoid damaging the port.
Usage recommendations
Verify switch and NIC compatibility with passive QSFP28 direct attach cables before installation and confirm firmware and speed settings for 100G operation. Use within the intended short-reach environment (within-rack or adjacent racks) and maintain standard ESD precautions during handling and installation.
