## Summary description

The BlueOptics CPAC-TR-40SPLIT-QSFP-5M-BL is a high-quality InfiniBand/fibre optic cable designed for efficient data transmission. With a length of 5 meters, it features a QSFP connector on one end and four SFP+ connectors on the other, allowing for versatile connectivity options. The male/male configuration ensures compatibility with various devices, making it ideal for data centers and networking applications.

## Long description

The BlueOptics CPAC-TR-40SPLIT-QSFP-5M-BL is a 5 m InfiniBand / fibre optic direct attach cable with a QSFP plug on one end and four SFP+ plugs on the other, male-to-male configuration. Designed for short-reach, high-speed links in racks and between adjacent racks, this MSA-compliant direct attach cable supports 40GBase-CR4 and 4x10GBase-CR electrical transmission profiles. The cable is intended for environments where consolidated 40 Gbps connectivity needs to be split into four 10 Gbps channels for switches, routers, storage systems and other networking equipment that accept QSFP-to-4xSFP+ split connections.
Advantages
This 5 m QSFP-to-4xSFP+ cable provides a compact, passive twinax solution for high-speed short-distance links with low latency and low power consumption. MSA compliance and the use of industry-standard connector formats ensure broad hardware compatibility with systems that support the respective 40GBase-CR4 / 4x10GBase-CR profiles. The split QSFP to four SFP+ arrangement allows flexible port aggregation or migration paths without additional transceivers, while the passive design reduces points of failure and simplifies installation in dense rack environments.
Suitable for
 Linking switches and top-of-rack hardware within the same rack or adjacent racks
 Breaking out a 40 Gbps QSFP link into four 10 Gbps SFP+ ports for servers or storage
 Short-reach connections in data centers using InfiniBand, Ethernet, FCoE or Fibre Channel protocols where passive DACs are supported
 Fast, low-latency interconnects in high-density network deployments
Key specifications
 Cable type: passive direct attach (twinax) with QSFP to 4×SFP+ split
 Length: 5 metres
 Supported link profiles: 40GBase-CR4 and 4×10GBase-CR (electrical DAC signalling)
 Wire gauge: 26 AWG (typical for this cable type)
 Connector configuration: male QSFP connector to four male SFP+ connectors
 Typical applications: InfiniBand, Ethernet, FCoE and Fibre Channel short-distance connections
How to use
Confirm that both endpoints support passive QSFP-to-4xSFP+ DACs and the intended 40G/10G electrical profiles. Power down or follow hot-plug procedures recommended by your hardware vendor before insertion if required. Insert the QSFP plug into the 40G QSFP port and place each SFP+ plug into the respective 10G SFP+ ports, ensuring secure latch engagement. Verify link negotiation and speed on connected devices and monitor for expected channel aggregation or split behaviour according to the host device documentation.
Usage recommendations
Use this cable for short-distance interconnects inside racks or between adjacent racks where passive DACs are supported. Avoid routing the cable across long distances, bending beyond the manufacturer’s minimum bend radius, or exposing the connectors to dust and mechanical stress. For environments requiring active signal conditioning or runs longer than 5 m, select an appropriate active DAC or optical transceiver solution.
