## Summary description

The BlueLAN QSFP-40G-3M-CM is a high-performance network cable designed for 40GBASE-CR4 applications. With a length of 3 meters and a 30AWG construction, it ensures reliable data transmission and minimal signal loss. This direct attach cable is compatible with Ethernet and Infiniband QDR standards, making it ideal for data centers and high-speed networking environments. Its blue color provides easy identification in cable management systems.

## Long description

The BlueLAN QSFP-40G-3M-CM is a 3 meter direct attach cable engineered for 40GBASE-CR4 applications. Constructed with 30AWG conductors and a QSFP form factor, this network cable supports 40 Gigabit Ethernet and Infiniband QDR interconnects. Its blue jacket aids visual identification in dense cabling environments while the twin-ax copper design provides low latency and predictable signal characteristics for short-reach data center links.
Advantages
This QSFP 40GBASE-CR4 cable offers a ready-to-deploy low-power alternative to optical modules for short links, with native compatibility for 40 Gigabit Ethernet and Infiniband QDR systems. The 30AWG construction balances flexibility and electrical performance to reduce insertion loss across the 3 meter length. The fixed-length direct attach design eliminates the need for separate transceivers and simplifies inventory management in rack and switch deployments.
Suitable for
 Short-reach 40GbE connections between switches and blade servers
 High-density data center top-of-rack and end-of-row cabling
 Infiniband QDR interconnects in HPC and storage clusters
 Environments where color-coded cable management improves maintenance
Key specifications
 Length: 3 meters
 Connector type: QSFP (QSFP+ compatible form factor)
 Application: 40GBASE-CR4 (40 Gigabit Ethernet), Infiniband QDR
 Conductor gauge: 30AWG twin-ax copper
 Transmission medium: Passive copper direct attach cable
 Cable color: Blue
 Typical use range: Short-reach interconnects within racks or between adjacent racks
How to use
Connect one QSFP connector to the QSFP port on the first device and the other end to the corresponding QSFP port on the second device. Ensure both devices support 40GBASE-CR4 or compatible Infiniband QDR operation before powering on the link. Route the cable to avoid sharp bends and maintain the manufacturer’s minimum bend radius; secure the cable with cable management hardware to prevent strain on the connectors. No transceivers or additional modules are required for operation, simplifying installation.
Usage recommendations
Use this direct attach cable for intra-rack or adjacent-rack 40GbE and QDR links where distances do not exceed the cable’s intended short-reach range. Verify switch and host compatibility with QSFP passive copper assemblies and follow standard ESD and handling procedures when installing. For longer distances or where optical isolation is required, consider optical transceiver solutions instead.
