Ideal for connecting switches and servers in data centers, this cable offers durability and flexibility, making it a perfect choice for high-speed networking environments.

## Long description

The BlueLAN LSWM1QSTK5 QSFP 40GBASE-CR4 5 Meter Blue is a direct attach copper (DAC) cable engineered for short-reach, high-bandwidth connections in data center and enterprise network environments. Built with 28AWG conductors and a 5 m length, this cable supports 40 Gigabit Ethernet and InfiniBand QDR link speeds, providing low latency and predictable signal integrity for switch-to-switch and switch-to-server interconnects.
Advantages
This direct attach cable delivers a cost-effective alternative to optical transceivers for short-distance links, offering low power consumption and minimal latency. The 28AWG construction balances flexibility and mechanical robustness, while the QSFP form-factor ensures compatibility with standard 40GBASE-CR4 QSFP ports. The assembled cable is designed for consistent impedance and reduced crosstalk, enabling stable 40 Gbps connections for high-throughput applications.
Suitable for
 40 Gigabit Ethernet switch-to-switch connections
 Switch-to-server links in rack and row topologies
 Short-reach InfiniBand QDR interconnects
 High-density patching in data center equipment racks
Key specifications
 Supported data rate: 40 Gbps
 Interface type: QSFP to QSFP (direct attach copper)
 Cable length: 5 meters
 Conductor size: 28 AWG
 Cable type: Twinax / Direct Attach Copper
 Typical use: Short-reach, high-bandwidth interconnects
How to use
Connect each QSFP connector to the corresponding QSFP port on your switches, servers or adapters. Ensure that both devices support 40GBASE-CR4 or InfiniBand QDR over DAC connections and that ports are powered down or in a safe state during installation if required by your equipment vendor. Route the 5 m cable to avoid sharp bends and mechanical stress; maintain the minimum bend radius recommended by your rack or cable management guidelines. Once connected, verify link status and correct speed/duplex settings in the device management interface.
Usage recommendations
Use the cable for short interconnects inside racks or between adjacent racks. For links longer than 5 meters or for extended reach requirements, consider using active optical solutions. Keep the cable free from tight bends and heavy compression, and match QSFP port compatibility from both ends to ensure reliable 40 Gbps operation.
