## Summary description

CBO DAC Cable QSFP28-DAC-1M is a 1 meter passive copper direct attach cable for 100G connections using QSFP28 interfaces. It provides a fixed, low-latency link between compatible QSFP28 ports for short-reach interconnects in switches, routers and servers. The cable requires no additional transceivers, reduces power consumption compared with optical modules, and is suitable for data center top-of-rack and aggregation links.

## Long description

CBO DAC Cable QSFP28-DAC-1M is a 1 meter passive copper direct attach cable designed for 100G connections between QSFP28 ports. The cable creates a fixed electrical link for short-reach interconnects, enabling low-latency data transfer between switches, routers and servers without the need for separate optical transceivers. Its passive design reduces power consumption compared with active optical modules and simplifies installation in data center top-of-rack and aggregation environments.
Advantages
The passive copper construction provides a reliable, low-latency 100 Gigabit link while eliminating the need for additional transceiver modules. The 1 m length is optimized for short-range connections inside racks and between adjacent equipment, reducing cable clutter and easing airflow management. Because it is a direct attach cable, it lowers both capital and operational costs by removing the power and heat overhead associated with active optical transceivers.
Suitable for
Top-of-rack 100G switch-to-switch links
Server-to-switch high-speed connections within a rack
Aggregation and leaf-spine short-reach interconnects
Environments prioritizing low latency and reduced power consumption
Key specifications
Connector type: QSFP28 to QSFP28
Data rate: 100 Gbit/s (aggregate)
Cable type: Passive copper direct attach
Length: 1 meter
Typical use: Short-reach, within-rack or adjacent-rack interconnects
Latency: Minimal, electrical direct attach link
How to use
Install the CBO DAC Cable by inserting each QSFP28 end into compatible QSFP28 ports on the devices to be connected. Ensure both ports support QSFP28 passive DACs and that devices are powered off or follow hot-plug guidelines provided by the equipment vendor. After seating the connectors, verify the link status through the network equipment management interface and check for expected port speeds and error-free operation.
Usage recommendations
Use the cable for short-distance connections inside racks or between adjacent racks. Avoid routing the cable near sources of electromagnetic interference and do not bend the cable sharply; maintain gentle bends to preserve signal integrity. Confirm compatibility with your network equipment's QSFP28 passive DAC support and monitor port temperature and link status after installation.
