Network Cable BlueOptics 980-9I35O-00W001 QSFP-DD BlueLAN DAC 1m Black

The BlueOptics 980-9I35O-00W001 QSFP-DD BlueLAN DAC 1m Black is a 1‑metre direct attach copper (DAC) cable with QSFP‑DD connectors, designed for short‑reach high‑speed interconnects in data centers and enterprise network racks. Its fixed 1 m length and robust construction provide low latency, high bandwidth interconnection between QSFP‑DD ports without the need for transceivers, enabling straightforward rack‑to‑rack or switch‑to‑switch links where optical conversion is unnecessary.

Advantages

This QSFP‑DD DAC cable offers reliable electrical signal integrity for multi‑terabit links while maintaining low power consumption compared with active optic solutions. The pre‑terminated copper design simplifies installation and reduces component count, and the cable’s shielded assembly helps to minimize electromagnetic interference in dense rack environments. The 1 m length balances flexibility and signal performance for short‑distance cabling within equipment cabinets and adjacent racks.

Suitable for

• High‑density switch interconnects in data centers
• Top‑of‑rack and end‑of‑row connections between networking devices
• Low‑latency links for storage arrays and compute clusters
• Environments where optical transceivers are not required or cost‑effective

Key specifications

• Connector type: QSFP‑DD to QSFP‑DD
• Cable type: Direct attach copper (DAC), passive
• Length: 1 metre
• Form factor: Quad small form‑factor, double density (QSFP‑DD)
• Suitable for multi‑lane high‑speed links (e.g., 100G/200G/400G implementations where supported)
• Shielding: Fully shielded assembly to reduce EMI
• Operating environment: Intended for use in rack and cabinet wiring within data center ambient conditions

How to use

Install the cable by aligning each QSFP‑DD connector with the corresponding port on network switches, routers, or NICs and insert until the connector latches. Ensure both devices are powered down or support hot‑plugging according to vendor guidance before insertion or removal. Route the 1 m cable to avoid sharp bends and maintain manufacturer‑recommended minimum bend radius. Verify link status through device LEDs or management interfaces once connections are made.

Usage recommendations

Use this passive QSFP‑DD DAC for short‑reach connections inside racks or between adjacent racks; do not exceed the recommended reach for passive copper to ensure signal integrity. Confirm compatibility with your networking equipment and firmware, and avoid excessive bending or mechanical stress to preserve performance.
