Network Cable BlueOptics 470-ABOX DAC QSFP28 SC282801L3M26 3m Blue

The BlueOptics 470-ABOX DAC QSFP28 SC282801L3M26 3m Blue is a direct attach copper (DAC) cable engineered for short-reach, high-bandwidth interconnects. At 3 meters length and conforming to the QSFP28 form factor, this cable supports high-speed connections between switches, routers and server ports that accept QSFP28 interfaces. Its design focuses on signal integrity, low latency and a robust outer jacket suitable for rack and data center environments.

Advantages

The DAC QSFP28 cable delivers reliable electrical performance for 100GbE and similar high-throughput links while avoiding the need for separate transceivers. Its fixed-configuration construction reduces component count and power consumption compared with optical transceiver solutions. The 3 m length provides a practical balance for in-rack and adjacent-rack connections, and the blue jacket enables quick visual identification in complex cabling runs.

Suitable for

• In-rack connections between QSFP28-enabled switches and servers
• Adjacent-rack links in data centers and server rooms
• High-performance computing clusters and storage fabrics
• Enterprise network aggregation and spine-leaf architectures

Key specifications

• Connector type: QSFP28 direct attach copper
• Length: 3 meters
• Typical supported data rate: 100 Gbps class links (QSFP28)
• Cable jacket color: blue
• Designed for short-reach electrical interconnects in rack environments

How to use

Install the DAC QSFP28 cable by aligning each QSFP28 connector with the device port and inserting until the latch engages. Ensure both ends are fully seated and the latch is secured to prevent accidental disconnection. Route the cable with gentle bends only, maintaining the manufacturer’s minimum bend radius for copper assemblies, and avoid tight kinks or sharp edges. For hot-pluggable ports, connect or disconnect while observing the device vendor’s hot-swap guidelines to prevent port or system issues.

Usage recommendations

For best performance, use this DAC cable for links within the same rack or between adjacent racks, avoid exceeding the intended reach for QSFP28 electrical interconnects, and keep cable runs free from mechanical stress and electromagnetic interference sources. Verify compatibility with device QSFP28 ports and firmware acceptance lists where applicable.
