## Summary description

The BlueOptics 40G-QSFP-4SFP-C-5M-BL is a high-performance InfiniBand/fibre optic cable designed for efficient data transmission. It features a length of 5 meters and connectors including one QSFP and four SFP+. This cable is ideal for connecting high-speed devices in data centers and networking environments, ensuring reliable performance and minimal signal loss.

## Long description

The BlueOptics 40G-QSFP-4SFP-C-5M-BL is a 5 metre direct attach twinax cable designed for short-range high‑speed connections in rack and adjacent‑rack environments. It features a QSFP connector on one end and four SFP+ connectors on the other, enabling a single 40G QSFP port to break out into four 10G SFP+ links. The cable follows MSA‑compliant electrical specifications and is intended for InfiniBand, 40G Ethernet and related 4x10G applications where passive twinax cabling is supported by hardware.
Advantages
This 5 m BlueOptics twinax DAC offers low latency, low power consumption and a compact physical profile suitable for dense cabling in data centres. As a passive 40GBase‑CR4 / 4x10GBASE‑CR cable it requires no active electronics for standard 10G links, which reduces failure points and energy draw. The cable is manufactured to MSA standards and built using industry‑grade components to provide consistent signal integrity and an extended operational lifetime for short‑reach connectivity.
Suitable for
Breaking out a 40G QSFP port into four 10G SFP+ ports in switches and routers
High‑speed server to switch connections inside racks and between adjacent racks
InfiniBand and Fibre Channel short‑reach links where passive twinax is supported
Storage arrays and network equipment requiring reliable 10G aggregation from a 40G port
Key specifications
Cable type: passive twinax / direct attach copper
Length: 5 metres
Connector configuration: 1×QSFP to 4×SFP+
Supported protocols: 40GBase‑CR4 and 4×10GBase‑CR electrical lanes; compatible with InfiniBand, 40G Ethernet, FCoE and Fibre Channel up to supported link rates
Wire gauge: 26 AWG
MSA compliant electrical and mechanical dimensions
How to use
Insert the QSFP plug into the 40G QSFP port and the four SFP+ plugs into the corresponding SFP+ ports on target devices. Ensure both ends are inserted fully and that the connected hardware supports passive twinax DAC breakout cables and the chosen transmission protocol. Use vendor documentation to verify port breakout and lane mapping settings where applicable. Avoid sharp bends or kinks and maintain recommended bend radii to preserve signal integrity.
Usage recommendations
For optimal reliability, use this cable for short‑range connections inside racks or between adjacent racks and confirm compatibility with your switch, router or storage system firmware. Keep the cable away from high‑EMI sources and follow data centre cable management practices to prevent undue stress on connectors. If your equipment requires active cables or optical transceivers, select those alternatives accordingly.
