## Summary description

3-meter CBO DAC cable QSFP28-DAC-3M is a Direct Attach Copper (DAC) passive twinax cable compatible with F5 Networks QSFP28 ports. Designed for short-reach connections in data centers and network racks, it provides a cost-effective, low-latency link for high-speed 100GbE or other QSFP28-capable equipment. Ideal for server-to-switch or switch-to-switch connections where a fixed, reliable copper link is required.

## Long description

The CBO DAC Cable QSFP28-DAC-3M is a 3-meter passive Direct Attach Copper (DAC) twinax cable designed for QSFP28 ports and compatible with F5 Networks equipment. It provides a fixed copper connection for short-reach links in data centers, server rooms, and network racks. Engineered for 100GbE and other QSFP28-capable interfaces, the cable offers a straightforward, low-latency connection without the need for optical transceivers.
Advantages
This 3 m DAC cable delivers low latency and reliable signal integrity for short-distance, high-speed links. As a passive twinax solution, it reduces overall power consumption compared with active optical solutions and eliminates the need to manage separate transceivers. The integrated QSFP28 connectors ensure compatibility with standard QSFP28 ports, simplifying installation and reducing points of failure.
Suitable for
 Short-reach 100GbE connections between servers and top-of-rack switches
 Switch-to-switch interconnects within the same rack or adjacent racks
 High-density data center topologies requiring fixed, low-latency links
Key specifications
 Length: 3 meters
 Connector type: QSFP28 to QSFP28 twinax
 Cable type: Passive Direct Attach Copper (DAC), twinax
 Supported data rates: up to 100 Gigabit Ethernet (QSFP28)
 Typical use: short-reach, rack-level interconnects
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring the latch engages securely. Verify that both devices support passive DAC connections and that port settings (speed/auto-negotiation) are configured for 100GbE or the appropriate QSFP28 mode. No separate transceivers or additional power sources are required; the cable is ready for immediate use once seated correctly in both ports.
Usage recommendations
Route the cable to avoid sharp bends and maintain bend radius recommended for twinax cabling. Use cable management within racks to prevent strain on the QSFP28 connectors and ensure adequate airflow around networking equipment. Confirm compatibility with the specific F5 Networks models in your deployment and test link status and performance after installation.
