## Summary description

Direct attach copper QSFP+ DAC from Extralink for 40Gbps links split to 4×10Gbps. Fixed 3 m cable length, 30AWG conductor, QSFP+ connectors on both ends (male/male) and full duplex operation. Designed for high-speed server, switch and NIC interconnects in data centers or aggregation racks where short-reach, low-latency copper connections are required.

## Long description

Extralink QSFP+ DAC cable is a fixed-length direct-attach copper assembly that provides a 40Gbps QSFP+ connection split into four independent 10Gbps lanes. The cable features QSFP+ male connectors on both ends, a 3 m nominal length and 30AWG conductors, and supports full-duplex operation for short-reach, low-latency interconnects in data center and aggregation rack environments.
Advantages
The passive copper design delivers low latency and consistent signal integrity for high-bandwidth links without requiring optical transceivers. A fixed 3 m length simplifies rack planning and cabling management while the QSFP+ to 4×10Gbps logical split enables flexible connectivity to switches, servers and network interface cards with 10Gbps lanes. The 30AWG conductor size balances flexibility and electrical performance for reliable short-reach links.
Suitable for
Server-to-switch direct connections in data center top-of-rack and end-of-row deployments
High-density switch-to-switch aggregation within the same rack or adjacent racks
Connecting multi-lane NICs to QSFP+ ports that require 4×10Gbps breakout
Key specifications
Data rate: 40 Gbps aggregated, split into 4×10 Gbps lanes
Connector type: QSFP+ male to QSFP+ male
Cable length: 3 meters
Conductor gauge: 30 AWG
Operation: Full duplex
Cable type: Direct attach copper (DAC), passive
How to use
Install the DAC by seating the QSFP+ connectors into compatible QSFP+ ports on both devices until the connectors latch. Ensure ports on both ends are configured for matching speed and lane mapping and that device firmware or switch settings support passive DAC connections. Route the cable to avoid sharp bends and maintain the recommended bend radius for 30AWG copper assemblies; avoid excessive strain on the connector ends. No additional power or optical modules are required.
Usage recommendations
Verify compatibility with the specific switch or NIC vendor documentation for passive QSFP+ DAC support and any required port settings. Use the 3 m length for short-reach top-of-rack or adjacent-rack connections; for longer distances, consider active copper or optical alternatives. Inspect connectors for debris and ensure proper seating during installation to maintain link reliability.
