## Long description

The BlueOptics FN-CABLE-QSFP+3 QSFP DAC 3m Black is a direct attach copper (DAC) cable designed for short-reach, high-speed interconnects in networking equipment. At 3 meters length, this QSFP+ passive cable supports multi-lane 40GbE links between switches, routers, network interface cards and other compatible QSFP+ ports. The black jacket and robust construction provide a compact, low-profile connection suitable for rack-mounted and chassis-based installations where predictable latency and bandwidth are required.
Advantages
This QSFP DAC cable offers a low-latency, low-power connection with minimal setup — no separate transceivers or fiber patching are needed. Its fixed 3 m length reduces signal loss for short runs while maintaining high bandwidth capacity. The cable’s compatibility with common QSFP+ ports and its sturdy external sheath contribute to a reliable physical link in dense cabling environments.
Suitable for
40 Gigabit Ethernet switch-to-switch connections
Server-to-switch uplinks in data centers
High-performance computing clusters and storage arrays
Short-reach interconnects inside racks and network cabinets
Key specifications
Connector type: QSFP+ direct attach copper (DAC)
Length: 3 meters
Supported link speed: up to 40 Gbps (multi-lane)
Cable jacket color: black
Form factor: passive, low-power, low-latency copper cable
How to use
Install the cable by firmly inserting each QSFP+ connector into the corresponding QSFP+ port on the devices to be linked, ensuring proper orientation and that retention latches engage. Verify link status and speed on both endpoints using the equipment management interface. For best results, route the cable to avoid sharp bends and excessive strain; use cable management panels or ties to maintain proper bend radius and prevent mechanical damage.
Usage recommendations
Use this QSFP+ DAC cable for short-distance, high-speed connections inside racks and chassis. Avoid running the cable through areas with high electromagnetic interference and do not exceed the specified 3 m length for reliable signal integrity. Store and handle the cable to prevent repeated flexing near the connector ends.
