Network Cable BlueOptics Mellanox ARZE compatible BlueLAN DAC QSFP SC252501K2M30 30m Black

The BlueOptics Mellanox ARZE compatible BlueLAN DAC QSFP SC252501K2M30 30m Black is a direct-attach copper (DAC) network cable engineered for short-range, high-speed interconnects in data centers and enterprise network environments. Built with QSFP connectors on each end, this 30-metre cable supports high-throughput links between switches, routers and servers while maintaining low latency and reliable signal integrity. The cable’s black jacket and robust construction are designed for professional installations where consistent performance and physical durability are required.

Advantages

This BlueLAN DAC cable provides a cost-effective solution for high-bandwidth connections with minimal configuration. Native QSFP terminations ensure compatibility with equipment that accepts QSFP form-factor cables, facilitating straightforward, plug-and-play deployment. The 30 m length allows flexible rack-to-rack and aisle-to-aisle connections without additional transceivers or fiber, and the cable’s shielding and build quality help reduce electromagnetic interference while supporting stable data transmission under continuous load.

Suitable for

• Interconnecting top-of-rack and spine switches in data centers
• Connecting high-performance servers to network switches
• Short-distance, high-bandwidth links in enterprise LAN and campus networks
• Environments requiring durable, low-latency copper connections

Key specifications

• Connector type: QSFP to QSFP
• Cable type: Direct-attach copper (DAC)
• Length: 30 metres
• Jacket color: Black
• Bandwidth: Designed for high-speed, multi-lane QSFP links (suitable for aggregated 40/56/100 Gbps class deployments depending on supported transceiver modes)
• Construction: Shielded assembly for reduced interference and improved signal integrity

How to use

Install the cable by inserting each QSFP connector into compatible ports on the devices to be linked, ensuring the connectors are oriented and seated correctly until the latch engages. Route the cable to avoid sharp bends and excessive stress on the connectors; maintain recommended bend radius for DAC assemblies. No additional configuration is typically required at the physical layer—verify link status through connected equipment management interfaces and confirm negotiated speeds and lanes in the switch or server firmware if necessary.

Usage recommendations

For reliable operation, use this DAC cable within short-reach scenarios up to 30 m and in equipment that supports QSFP direct-attach copper connections. Avoid prolonged exposure to temperatures or mechanical strain outside the equipment manufacturer’s guidelines. When installing in dense racks, label both ends for easier maintenance and verify link parameters after installation to ensure expected throughput and lane configuration.
