Network Cable BlueOptics 980-9I48Z-00W002 QSFP-DD/2xQSFP56 2m Blue

The BlueOptics 980-9I48Z-00W002 QSFP-DD/2xQSFP56 2m Blue network cable is a high-density interconnect designed for short-reach, high-bandwidth links in data centers and enterprise networks. This 2 meter cable provides a direct electrical connection between a QSFP-DD port and two QSFP56 ports, enabling aggregation or breakout configurations where a single high-speed interface is split into two 200/100/50G-capable links depending on the host and module support. The cable’s blue jacket and compact form factor make it easy to identify and route within racks and patch panels while its construction supports reliable signal integrity for multi-lane serial transmission.

Advantages

This QSFP-DD to 2xQSFP56 cable offers a compact, low-latency alternative to optical transceivers and fiber for short interconnects, reducing power consumption and eliminating the need for separate optical modules. Its direct-attached design simplifies installation and lowers overall system cost for compatible switches and servers. The 2 meter length balances flexibility and neat cable management in server racks and network closets, while the robust jacket and connector strain relief improve durability under regular reconfiguration and handling.

Suitable for

• High-speed switch-to-switch or switch-to-server connections within the same rack or adjacent racks
• Breakout configurations where a QSFP-DD port is split into two QSFP56 links
• Top-of-rack aggregation and spine-leaf fabric short-reach links
• Environments requiring reduced power and latency compared with optical transceivers

Key specifications

• Connector type: QSFP-DD (one end) to 2 × QSFP56 (other end)
• Cable length: 2 meters
• Cable color: blue
• Transmission: multi-lane electrical direct attach supporting high-bandwidth lanes
• Typical use: short-reach direct-attach connections in data centers
• Form factor: passive direct-attach copper assembly for low-latency links

How to use

Connect the QSFP-DD end to the host port that supports QSFP-DD breakout functionality and plug the two QSFP56 ends into the target ports on the receiving devices. Ensure that the equipment firmware and port configurations support the required breakout mode and lane speeds before powering traffic. Route the cable to avoid sharp bends and excessive tension; use proper cable management to maintain airflow and ease of access. For population changes, power down or place ports in maintenance mode if the manufacturer recommends it, then reseat the cable as needed.

Usage recommendations

Use this direct-attach cable for short-distance links within the same rack or adjacent racks where optical transceivers are unnecessary. Verify switch and server compatibility with QSFP-DD to QSFP56 breakout connections and confirm supported speeds in device documentation. Avoid installation near strong electromagnetic sources and follow vendor guidelines for maximum insertion cycles and handling to prolong service life.
