## Long description

The CBO QSFP-40G-CU1M-BL is a passive direct attach copper (DAC) QSFP cable with a 1 meter length and QSFP+ male connectors on both ends, designed for 40 Gbit/s short-reach links. It provides a low-latency, low-power connection for high-density network environments such as data centers and server racks. The cable is intended for direct QSFP-to-QSFP connections between switches, routers and network interface cards where a reliable, cost-effective 40GbE link is required.
Advantages
This 1 m QSFP Direct Attach Copper Cable delivers predictable performance with negligible signal conversion latency because it is a passive electrical interconnect. It requires no external power or transceivers, reducing power consumption and simplifying deployment. The integrated QSFP+ male connectors ensure a snug fit and easy plug-and-play installation, while the short copper length helps minimize cost compared with active optical alternatives for short links.
Suitable for
 Inter-switch connections in top-of-rack or spine-leaf architectures
 Connecting routers and network interface cards supporting QSFP+
 Short-reach 40GbE uplinks within server racks and appliance clusters
 Temporary or permanent links in test labs and staging environments
Key specifications
 Connector type: QSFP+ male to QSFP+ male
 Length: 1 meter
 Data rate: up to 40 Gbit/s
 Cable type: passive direct attach copper (DAC)
 Typical use: short-reach, high-density rack connections
How to use
Install the QSFP Direct Attach Copper Cable by inserting each QSFP+ male connector into the corresponding QSFP port until the latch engages. Confirm the host devices recognize the link and monitor port status via network management tools. For best reliability, ensure ports are powered down or follow hot-plug guidance from the equipment vendor if required, and avoid sharp bends at the cable ends to maintain signal integrity.
Usage recommendations
Use this cable for short-distance 40GbE connections where low latency and low power consumption are priorities. Verify compatibility with the QSFP ports on both devices before installation, and route the cable to avoid mechanical stress and excessive heat near power-dense equipment.
