## Summary description

The BlueOptics BN-QS-SP-CBL-1M-IB-BL is a 1 meter InfiniBand/fibre optic cable featuring a QSFP connector on one end and four SFP+ connectors on the other. This male-to-male cable is designed for high-speed data transmission in data centers and networking environments, ensuring reliable connectivity and performance.

## Long description

The BlueOptics BN-QS-SP-CBL-1M-IB is a 1 metre InfiniBand/fibre optic direct attach cable (DAC) with a QSFP plug on one end and four SFP+ plugs on the other. This male-to-male cable is designed for short-reach, high-speed interconnects in rack and adjacent-rack environments and supports 40GBase-CR4 and 4x10GBase-CR electrical signal transmission over twinax copper. The construction follows MSA conventions and is intended for use with hardware platforms that officially support the same form factor and transmission protocols.
Advantages
The cable provides a compact, single-cable solution to split a 40 Gbps QSFP connection into four 10 Gbps SFP+ links while avoiding active transceivers. As a passive twinax direct attach cable with 30 AWG conductors, it offers low latency and very low power consumption. Manufacturing according to MSA-compatible standards and the use of high-quality components aim to deliver consistent connectivity and long operational life suitable for dense data centre or network rack deployments.
Suitable for
Short-range connections between switches, routers and storage within the same rack or adjacent racks
Breaking out a 40G QSFP port into four 10G SFP+ ports for server or appliance connections
InfiniBand, 40G Ethernet, 4x10G Ethernet and compatible data centre interconnects
Key specifications
Cable type: passive twinax direct attach cable (DAC)
Length: 1 metre
Connector types: QSFP (male) to 4 × SFP+ (male)
Supported protocols: 40GBase-CR4 and 4×10GBase-CR (electrical)
Conductor gauge: 30 AWG
Design: MSA-compatible form factor for QSFP and SFP+ interfaces
How to use
Install the QSFP end into a compatible 40G QSFP port and plug the four SFP+ ends into the corresponding SFP+ ports of target devices. Confirm that the connected hardware supports passive twinax DACs and the intended protocols (40GBase-CR4 or 4×10GBase-CR). No external power or additional transceivers are required for passive operation; configuration and link negotiation are performed by the connected devices according to their firmware and operating system settings.
Usage recommendations
For reliable operation, use the cable for short-distance links within racks or between adjacent racks only, verify device compatibility with passive QSFP-to-4×SFP+ DACs, and avoid sharp bends or mechanical stress on the cable and connectors. Regularly inspect connectors for contamination and ensure firmware and hardware settings on network devices support the intended breakout configuration.
