## Summary description

CBO QSFP28 DAC Cable BlueLAN SC282801L2M30 is a 2-meter direct attach copper cable (DAC) with QSFP28 connectors for high-speed server, switch and storage interconnects. Designed for short-reach 100Gbps links, it provides a low-latency, cost-effective connection for data center top-of-rack and aggregation deployments where active optics are unnecessary.

## Long description

BlueOptics Direct Attach Cable CBO QSFP28 DAC Cable BlueLAN SC282801L2M30 2 m is a 2-meter passive copper twinax assembly with QSFP28 connectors, engineered for short-reach 100Gbps links between servers, switches and storage systems. The cable supports direct attach connectivity for top-of-rack and aggregation layers in data centers where a low-latency, energy-efficient and cost-effective link is required. Intended for environments that do not require active optical transceivers, this DAC provides a compact physical connection for high-density racks.
Advantages
The QSFP28 DAC offers low latency and minimal signal conversion overhead by using direct copper interconnects. As a passive twinax solution it reduces power consumption compared with active optical modules and eliminates the need for separate transceivers, simplifying inventory and lowering per-link cost. Its 2 m length is suitable for most within-rack and adjacent-rack connections while the QSFP28 interface ensures compatibility with 100GbE ports supporting DAC connectivity.
Suitable for
 Short-reach 100Gbps interconnects between servers and switches within the same rack
 Top-of-rack (ToR) and aggregation layer links in data centers
 High-density rack deployments where cost and power efficiency are priorities
 Environments that prefer passive copper connections over active optics
Key specifications
 Connector type: QSFP28 to QSFP28
 Nominal link speed: 100 Gbps
 Cable type: Passive twinax copper
 Length: 2 meters
 Typical use: Short-reach, within-rack and adjacent-rack connections
 Suitable for: 100 Gigabit Ethernet ports supporting DAC
How to use
Insert each QSFP28 connector into the matching 100GbE QSFP28 port on your networking equipment until the latch engages. Ensure both devices are powered down or that hot-swap procedures recommended by the equipment vendor are followed if inserting into live systems. After physical connection, verify link status in the switch or server management interface and confirm negotiated speed and link integrity. For reliable operation, route the cable to avoid sharp bends and mechanical strain on connector ends.
Usage recommendations
Use this 2 m passive QSFP28 DAC for within-rack or adjacent-rack connections where short, high-bandwidth links are needed. Avoid installing in runs longer than the specified length and prevent repeated flexing near the connector to maintain signal integrity and connector lifetime.
