BlueOptics QSFP56 Direct Attach Cable (DAC) BL070701W2M30, compatible with 980-9I54I-00V01A, 2 m

BlueOptics QSFP56 Direct Attach Cable (DAC) BL070701W2M30 is a 2 m passive copper cable designed for short-reach 100G interconnects. It provides a direct electrical connection between QSFP56 ports on network equipment and is commonly used in data center and rack environments for server-to-switch and switch-to-switch links where low latency and reliable throughput are required. This DAC eliminates the need for separate optical transceivers, simplifying installation and reducing power consumption for dense, high-speed topologies.

Advantages

The BlueOptics QSFP56 DAC offers low latency and consistent signal integrity over its 2 m length, making it suitable for high-performance networking. Passive design means no additional power draw for transceiver modules, and the direct attach form factor reduces component count and simplifies rack cabling. Its QSFP56 interface ensures compatibility with equipment that supports 100G electrical connections and allows straightforward hot-plug installation for maintenance or upgrades.

Suitable for

• 100G server-to-switch connections in data centers
• Switch-to-switch uplinks within racks or across adjacent racks
• High-throughput, low-latency applications such as storage and compute clusters
• Environments where optical transceivers are unnecessary or unwanted

Key specifications

• Connector type: QSFP56 to QSFP56 direct attach copper
• Length: 2 meters
• Data rate: Designed for 100 Gbit/s links (QSFP56 electrical)
• Cable type: Passive copper twinax
• Typical use: Short-reach interconnects within racks and adjacent racks

How to use

Insert each QSFP56 connector into the corresponding port on your network devices until the latch engages. Ensure both ends are fully seated and device interfaces are enabled and configured for 100G operation. Check link status on connected equipment and verify correct speed and lanes in the device management interface. For replacement or hot-swap, gently depress the latch and pull straight out to avoid damaging the port.

Usage recommendations

Use the cable for short-distance links inside racks or between adjacent racks; avoid routing through sharp bends or areas with excessive mechanical stress. Keep connectors clean and handle by the module housing to prevent contamination. Confirm device compatibility with QSFP56 passive DACs before deployment and verify link settings after installation.
