## Summary description

The BlueLAN QSFP-40G-1M-CM is a high-performance direct attach cable designed for 40G Ethernet and Infiniband QDR applications. With a length of 1 meter and a 30AWG construction, it ensures reliable data transmission with minimal latency. The cable features QSFP connectors for easy plug-and-play installation, making it ideal for data centers and high-speed networking environments.

## Long description

The BlueLAN QSFP-40G-1M-CM is a 1-meter direct attach cable designed for 40G Ethernet and InfiniBand QDR environments. Constructed with 30AWG conductors and QSFP connectors on both ends, the cable provides a low-latency, high-bandwidth physical link for short-reach connections inside racks and between adjacent network equipment. Its plug-and-play QSFP interface enables simple installation without additional transceivers, supporting standard 40GBASE-CR4 signaling for compatible switches, routers and host adapters.
Advantages
This direct attach cable delivers predictable electrical performance for 40G links while reducing system cost and power compared to optical transceivers. The 1 m length minimizes excess cable slack in dense rack deployments and helps maintain signal integrity. QSFP connectors provide a secure mechanical fit and straightforward hot-pluggable operation. The 30AWG construction balances flexibility and shielding to support reliable short-range data transfer with low latency and consistent throughput.
Suitable for
 Top-of-rack and middle-of-row switch-to-switch connections
 Server to network adapter links in data centers
 High-performance computing clusters using InfiniBand QDR
 Short-reach interconnects where 40GBASE-CR4 is supported
Key specifications
 Connector type: QSFP on both ends
 Nominal length: 1 meter
 Cable gauge: 30 AWG
 Protocol support: 40G Ethernet, InfiniBand QDR
 Signaling standard: 40GBASE-CR4
 Typical use: Short-reach direct attach copper
How to use
Install the BlueLAN QSFP direct attach cable by aligning the QSFP connectors with the corresponding QSFP ports on your network equipment and inserting until the latch engages. No external transceivers or additional configuration are required for native 40GBASE-CR4 or InfiniBand QDR links when the connected devices support direct attach copper. Route the cable within the rack to avoid sharp bends and maintain bend radius consistent with datasheet guidance. For hot-plug operations, ensure the host equipment supports hot-pluggable QSFP modules and follow standard electrostatic discharge precautions during handling.
Usage recommendations
Use this cable for short-reach, high-bandwidth connections where cost, power consumption, and latency are priorities. Avoid using beyond its intended 1 m reach and verify compatibility with equipment QSFP port firmware and vendor support lists when deploying in production environments.
