Network Cable BlueOptics Mellanox 00KF005 QSFP DAC SC252501K2M30 2m Blue

The BlueOptics Mellanox 00KF005 QSFP DAC SC252501K2M30 2m Blue is a direct attach copper (DAC) cable designed for short-reach, high-speed interconnects in networking and data center environments. Featuring QSFP connectors at both ends and a 2 meter length, this blue cable provides a low-latency, high-bandwidth connection suitable for switch-to-switch, switch-to-server, and server-to-server links where compatible QSFP ports are available. The cable is intended for reliable signal integrity over short distances and offers a compact, passive solution that requires no additional transceivers.

Advantages

This DAC cable provides high data throughput with minimal latency while eliminating the need for separate optical transceivers, reducing component count and power consumption. Its QSFP form factor ensures wide compatibility with devices that support QSFP DAC interconnects. The 2 meter length balances reach and manageability in rack and cabinet installations, and the pre-terminated, factory-tested construction supports consistent electrical performance and easy plug-and-play deployment.

Suitable for

• Short-reach high-speed links between switches and servers in data centers
• Top-of-rack and end-of-row network cabling where QSFP ports are used
• High-performance computing clusters requiring low-latency interconnects
• Environments where reduced power and component count are desired

Key specifications

• Connector type: QSFP to QSFP
• Medium: direct attach copper (DAC), passive
• Length: 2 meters
• Color: blue
• Typical use: short-range, high-bandwidth interconnects
• Latency characteristics: low-latency electrical link

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on network devices until the latch engages. Ensure devices are powered down or follow live hot-plug procedures recommended by the device manufacturer. Verify port compatibility and link negotiation settings in the device management interface. After connection, check link status indicators and system logs to confirm that the link is active and operating at the expected speed.

Usage recommendations

For reliable operation, route the cable to avoid sharp bends and excessive stress on the connectors. Use the 2 meter length for connections within the same rack or adjacent racks to maintain signal integrity. Confirm device compatibility with QSFP passive DACs and consult equipment documentation for supported link speeds and lane configurations before deployment.
