## Summary description

Passive copper Direct Attach Cable (DAC) CBO QSFP28-DAC-2M is a 2-metre QSFP28-to-QSFP28 assembly for short-reach 100GbE or compatible QSFP28 applications. It provides a fixed, low-latency connection without SFP modules, suitable for switches, routers and servers in data centers, offering simplified cabling and reduced power consumption.

## Long description

The BlueOptics DAC cable CBO QSFP28-DAC-2M is a 2-metre passive copper assembly that connects QSFP28 ports directly for short-reach 100GbE and compatible QSFP28 applications. Designed for use in high-density data center environments, this fixed copper cable eliminates the need for separate optical transceivers, providing a low-latency, power-efficient link between switches, routers and servers. The cable supports a straightforward plug-and-play installation and is intended for top-of-rack and adjacent-rack connections where cable length and signal integrity requirements are met.
Advantages
This passive DAC offers reduced power consumption compared with optical transceiver solutions because no active conversion is required. The fixed QSFP28-to-QSFP28 design simplifies cabling by providing a single integrated assembly that ensures consistent electrical performance and low latency. The short 2 m length is suitable for dense rack-to-rack or server-to-switch connections, helping to reduce clutter and improve airflow in racks. The cable is compatible with standard QSFP28 interfaces and is built to industry signal integrity expectations for 100GbE links.
Suitable for
Short-reach 100 Gigabit Ethernet connections in data centers
Direct QSFP28 port interconnects between switches, routers and servers
Top-of-rack and adjacent-rack cabling where a 2 m passive cable meets distance needs
Power-sensitive environments seeking lower link power consumption
Key specifications
Connector type: QSFP28 to QSFP28
Cable length: 2 metres
Type: Passive copper Direct Attach Cable (DAC)
Supported link: Up to 100GbE and compatible QSFP28 protocols
Latency: Low, fixed electrical connection without transceiver conversion
Usage environment: Data center short-reach interconnects
How to use
Install the cable by inserting each QSFP28 connector into the corresponding port on the devices until the latch engages. Ensure both ports support passive DAC connections and that the connected equipment is configured for the intended 100GbE or compatible link speed. Avoid sharp bends and maintain recommended bend radius for copper assemblies. If hot-plugging, follow device vendor guidelines; verify link status and interface settings in the host equipment after connection.
Usage recommendations
For reliable operation, use the 2 m passive DAC for short, direct interconnects inside racks or between adjacent racks. Confirm compatibility with your switch or server vendor and consult equipment documentation for supported passive QSFP28 assemblies. Avoid exceeding the cable’s intended distance and protect connectors from dust and mechanical stress when not in use.
