## Long description

The BlueOptics ET6402-10DAC-2M-BL InfiniBand and Fibre Optic Cable is a breakout direct attach cable engineered for high-speed networking environments. Featuring a passive 40 Gigabit to 4x10 Gigabit twinaxial copper configuration, this 2-meter black cable provides a reliable physical link for networking hardware. It is equipped with a QSFP connector on one end and four SFP+ connectors on the other, facilitating efficient data transmission within server racks and adjacent data center infrastructure.
Advantages
This direct attach copper cable offers a cost-effective and energy-efficient solution for short-range interconnects, eliminating the need for separate optical transceivers and patch cables. The passive copper design ensures low power consumption and minimal latency for high-performance computing applications. Its sturdy construction and factory-terminated connectors guarantee stable signal integrity and straightforward plug-and-play installation in professional data center deployments.
Suitable for
Connecting 40GbE switches to multiple 10GbE servers
Data center rack and inter-rack hardware connections
High-performance computing and InfiniBand environments
Short-range network switch and router uplinks
When it may not be suitable
This passive copper breakout cable is not suitable for long-distance runs exceeding its 2-meter length limitation. It cannot be used to connect equipment requiring optical fiber media or environments that demand galvanic isolation between interconnected networking devices.
Key specifications
Cable length: 2 m
Connector 1: QSFP
Connector 2: 4xSFP+
Data transfer rate: Up to 40 Gbps on QSFP and 10 Gbps per SFP+ channel
Media type: Twinaxial copper
Color: Black
How to use
Ensure that your networking equipment is powered down or supports hot-swapping before installation. Take the QSFP end of the cable and firmly plug it into the 40G port of your source switch or router until the retention latch clicks into place. Take the four SFP+ ends and insert them into the corresponding 10G ports on your receiving network hardware or servers. Route the 2-meter cable carefully through the rack cable management channels to avoid sharp bends or excessive strain on the connectors.
What to consider before purchase
Verify that your network hardware is compatible with BlueOptics direct attach cables
Measure the physical distance between devices to ensure the 2-meter length is sufficient
Check the port configuration on your switches to confirm the need for a QSFP to 4xSFP+ breakout layout
Always inspect the connectors for dust or damage prior to insertion and avoid bending the twinaxial copper cable beyond its minimum bend radius to maintain optimal signal performance.
