## Summary description

CBO QSFP28-DAC-2M is a 2-meter passive copper DAC (Direct Attach Cable) designed for 100G networking. It features QSFP28 connectors at both ends for direct high-speed connections between switches, routers or servers. Suited for short-range interconnects in data centers and server racks, it offers low latency, simple plug-and-play installation and reduced power consumption compared with active optical modules.

## Long description

The CBO QSFP28-DAC-2M 2m passive copper 100G is a 2-meter direct attach cable with QSFP28 connectors on both ends engineered for short-range 100 gigabit Ethernet connections. It provides a straightforward plug-and-play link between QSFP28 ports on switches, routers or servers without the need for transceivers, making it suitable for top-of-rack and adjacent-rack interconnects in data centres and server rooms. As a passive copper DAC, it delivers low latency and minimal additional power draw compared with active optical solutions.
Advantages
This passive copper DAC simplifies cabling by combining connector and cable in a single assembly, eliminating separate transceiver modules and simplifying inventory. The 2 m length supports flexible rack-to-rack or within-rack placement while maintaining signal integrity for 100G links. The QSFP28 interface ensures compatibility with equipment supporting QSFP28 Direct Attach Cabling and provides a low-latency, low-power option for high-bandwidth short-reach connections.
Suitable for
Top-of-rack and adjacent-rack 100G uplinks and switch-to-switch connections
Server to switch interconnects inside the same rack or neighbouring racks
High-density data centre environments where short, reliable 100G links are required
Key specifications
Connector type: QSFP28 to QSFP28
Cable type: Passive copper direct attach cable
Length: 2 meters
Nominal data rate: 100 Gbps
Latency: low, suitable for latency-sensitive applications
Power: passive design with minimal additional power consumption
Typical use range: short-reach interconnects within racks and between adjacent racks
How to use
Insert each QSFP28 plug into the corresponding QSFP28 port on network switches, routers or servers until the latch engages. Confirm link status through device LEDs or management interfaces and ensure both ends are configured for 100G operation if the equipment requires manual port settings. Avoid excessive cable bending and maintain proper bend radius near the connector. For maintenance, disconnect by pressing the connector latch and pulling straight out to avoid stressing the port.
Usage recommendations
Use the 2 m passive QSFP28-DAC for short, fixed interconnects where low latency and low power are priorities; verify equipment compatibility with QSFP28 passive DACs in device documentation before deployment.
