## Summary description

The BlueOptics CPAC-TR-40SPLIT-QSFP-3M-BL is a 3-meter InfiniBand/fibre optic cable featuring QSFP to 4xSFP+ connectors. Designed for high-speed data transfer, it ensures reliable connectivity in data centers and networking environments. The male/male connectors provide versatility for various applications, making it an essential component for efficient data communication.

## Long description

The BlueOptics CPAC-TR-40SPLIT-QSFP-3M-BL is a 3-meter QSFP to 4xSFP+ direct attach cable (DAC) designed for short-reach, high-speed connections in data centers and network racks. As a passive twinax copper solution with QSFP male to four SFP+ male ends, it supports aggregated 40GBase-CR4 links or four independent 10GBase-CR channels over a 3 m span. The cable follows industry MSA guidelines and is intended for use where low latency, low power draw and reliable electrical signal transfer are required between compatible switches, routers, storage systems and network interface cards.
Advantages
This 3 m QSFP to 4xSFP+ DAC provides a cost-effective and energy-efficient method to establish high-throughput rack and adjacent-rack connections. The passive twinax construction eliminates the need for active components, reducing power consumption and improving reliability for short distance interconnects. Compliance with MSA form-factors ensures mechanical and electrical compatibility with a wide range of hardware platforms that support QSFP to SFP+ split configurations.
Suitable for
 High-speed server-to-switch connections inside racks
 Inter-switch links between adjacent racks or top-of-rack (ToR) deployments
 Consolidation of four 10G links into a single 40G QSFP port
 Short-reach Fibre Channel, FCoE or InfiniBand compatible setups where passive DACs are supported
Key specifications
 Length: 3 meters
 Connector type: QSFP male to 4 × SFP+ male
 Data rate support: up to 40 Gbps aggregated or 4 × 10 Gbps channels
 Cable type: passive twinax copper (30 AWG conductors)
 Form-factor compliance: MSA-compliant QSFP and SFP+ mechanical interfaces
 Typical applications: Ethernet, FCoE, Fibre Channel and InfiniBand (when host hardware supports passive DAC)
How to use
Connect the QSFP end to a compatible 40G QSFP port on a switch or NIC and plug the four SFP+ ends into the target SFP+ ports on the receiving device, or use the reverse orientation as required by your hardware. Ensure both devices support passive QSFP-to-4×SFP+ split operation and the intended protocol (e.g., 40GBase-CR4 or 4×10GBase-CR). Avoid sharp bends and secure cable routing inside racks to prevent strain on the connectors. If a device requires breaking out the 40G port in software or BIOS settings, configure the port according to the vendor instructions prior to traffic activation.
Usage recommendations
Use this passive DAC for short-distance links within racks or between adjacent racks where passive twinax is supported by your hardware. Verify vendor compatibility with QSFP-to-SFP+ split cables and confirm firmware or port mode settings if necessary. For longer distances or where electrical isolation is required, consider optical transceivers and fiber cables instead.
