Network Cable BlueOptics 470-ABPW DAC QSFP28 SC282801L0.5M30 470-ABPW-BL BlueLAN

The BlueOptics 470-ABPW DAC QSFP28 SC282801L0.5M30 is a 0.5 metre direct attach copper (DAC) cable designed for high-speed short-reach connections in data centers and enterprise networks. It supports QSFP28 interfaces to deliver multi-gigabit throughput with low latency and stable signal integrity. The cable's compact length and rugged construction make it suitable for top-of-rack and adjacent-rack connections where space and performance are priorities.

Advantages

This DAC QSFP28 cable provides high bandwidth and low latency for server-to-switch and switch-to-switch links, while its short 0.5 m length reduces signal loss and crosstalk. The BlueOptics construction ensures mechanical robustness and consistent electrical performance under continuous operation. Its ready-made connector assembly simplifies installation without the need for additional transceivers, supporting straightforward, cost-effective deployment in dense network environments.

Suitable for

• Short-reach connections between servers and switches in racks
• High-density top-of-rack and spine-leaf network setups
• Data centre links requiring QSFP28-compatible multi-gigabit connectivity

Key specifications

• Interface type: QSFP28 direct attach copper (DAC)
• Cable length: 0.5 metres
• Data rate: supports multi-gigabit QSFP28-class throughput
• Connector form factor: QSFP28 on both ends for plug-and-play connectivity
• Cable construction: shielded copper assembly for reduced interference
• Intended use: short-reach interconnects in rack environments

How to use

Connect one QSFP28 end to the QSFP28 port on the network switch or transceiver-equipped device and the other end to the corresponding QSFP28 port on the server or adjacent switch. Ensure ports are powered down or follow hot-plug guidelines of the equipment vendor if required. Confirm link status in device management interfaces and verify negotiated data rates. Route the 0.5 m cable to avoid sharp bends and maintain proper airflow within the rack.

Usage recommendations

For reliable operation, install the cable in short, unobstructed paths within rack rows, avoid exceeding recommended bend radii, and verify compatibility with device QSFP28 ports before deployment. Regularly inspect connectors for dust and debris and follow equipment vendor guidelines for hot-plugging and firmware-supported link settings.
