Compatible Cisco QSFP-4SFP10G-CU3M BlueLAN Passive 40GBASE-CR4 QSFP to 4x10GBASE-CR SFP+ Direct Attach Breakout Cable, 3 Meter, AWG30 (QSFP-4SFP10G-CU3M-BL)

The BlueLAN QSFP-4SFP10G-CU3M-BL is a high-performance passive direct attach breakout cable (DAC) designed for 40 Gigabit Ethernet connectivity. It converts a single QSFP+ port into four 10 Gigabit SFP+ ports, providing a cost-effective and low-latency solution for data center and enterprise network environments. This cable is fully compatible with Cisco QSFP-4SFP10G-CU3M equipment and meets IEEE 802.3ba 40GBASE-CR4 and SFF standards.

Advantages

This breakout cable offers significant advantages over traditional fiber transceivers and cabling. It provides a plug-and-play solution with no configuration required, reduces power consumption, and minimizes cable clutter by consolidating four 10G links into a single QSFP+ connection. The passive design ensures zero latency and high reliability, making it ideal for high-density network topologies.

Suitable for

• Data center top-of-rack (ToR) and end-of-row (EoR) switch connectivity
• Connecting servers and storage devices to 40G uplinks
• High-performance computing (HPC) clusters
• Network switches, routers, and SAN infrastructure
