Network Cable BlueOptics Mellanox ARZC compatible BlueLAN DAC QSFP SC252501K1M30 ARZC-BL 1m Blue

The BlueOptics Mellanox ARZC compatible BlueLAN DAC QSFP SC252501K1M30 ARZC-BL 1m Blue is a direct-attach copper (DAC) network cable designed for short-reach, high-bandwidth connections in server rooms and data centers. This 1 metre cable provides a factory-terminated QSFP connector interface for use with compatible Mellanox and other QSFP ports, enabling low-latency, energy-efficient links between switches, routers and network interface cards. The blue jacket gives a clear visual identifier for cabling runs and rack organisation.

Advantages

The cable offers a compact, low-power alternative to optical transceivers with minimal signal loss over short distances. Its pre-terminated QSFP connections reduce installation time and help ensure reliable mating with QSFP ports. The robust jacket and strain relief protect internal conductors from mechanical stress, while the fixed-length design eliminates the need for separate transceivers and patch cords for compatible equipment.

Suitable for

• Short-reach interconnects between switches and top-of-rack devices
• High-density data center environments where low latency is required
• Server-to-switch connections in rack-mounted installations
• Environments where power efficiency and reduced heat are important

Key specifications

• Connector type: QSFP direct-attach copper (factory-terminated)
• Length: 1 metre
• Color: blue jacket for easy identification
• Application: short-reach, high-bandwidth interconnects
• Performance: designed for low latency and energy-efficient operation over short distances
• Construction: molded connector housings with strain relief and durable outer jacket

How to use

Confirm that both endpoints support QSFP direct-attach copper connections and that the port specifications match the cable performance. Power down equipment if recommended by the hardware vendor, insert each QSFP connector into the corresponding port until it latches, and route the cable to avoid sharp bends and excessive tension. After connection, verify link status via the host device indicators or management interface and monitor traffic to confirm expected throughput.

Usage recommendations

For optimal performance, use the cable for short-distance links within racks or between adjacent racks, avoid tight bend radii, and keep the cable clear of heat sources. When installing in high-density environments, label both ends to simplify maintenance and ensure compatibility with the port vendor's QSFP specifications before deployment.
