Product information

Description

The BlueOptics QSFP-4SFP10G-CU4M-BL is a 5 m InfiniBand/fibre optic direct attach cable with a QSFP connector on one end and four SFP+ connectors on the other, wired male-to-male. Designed for short-reach, high-speed interconnects, this 40G-to-4x10G passive twinax cable supports multi-protocol environments including Ethernet, FCoE, Fibre Channel and InfiniBand, and is suitable for linking devices inside racks or between adjacent racks.

Advantages

This cable implements a passive 40GBase-CR4 / 4x10GBASE-CR twinax copper design with 26 AWG conductors and MSA-compliant connectors, offering low latency and low power consumption. It provides tested compatibility with major hardware platforms that accept QSFP-to-4xSFP+ direct attach assemblies. Built from industry-standard components, the product provides stable electrical signal transfer over the 5 metre distance and is intended for long service life and low maintenance.

Suitable for

  • High-density switch-to-switch connections within and between adjacent rack units
  • Aggregation links and top-of-rack switch uplinks requiring 40G to 4×10G breakout
  • Short-reach server, storage and network equipment interconnects
  • Environments using Ethernet, FCoE, Fibre Channel or InfiniBand protocols at up to 40G

Key specifications

  • Cable length: 5 metres
  • Connector types: 1×QSFP male to 4×SFP+ male
  • Transmission type: passive twinax copper (DAC), 40GBase-CR4 / 4×10GBASE-CR
  • Conductor size: 26 AWG
  • Standards: MSA-compliant QSFP and SFP+ interfaces
  • Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand (up to 40G aggregate)

How to use

Install the cable by inserting the QSFP plug into a QSFP port on a switch or adapter and the SFP+ plugs into the corresponding SFP+ ports on target devices, observing port orientation and retaining latches. Ensure connected devices support passive QSFP-to-4xSFP+ breakout cables and the chosen transport protocol. No external power or configuration is required for the cable itself; any required link negotiation or speed settings are handled by the connected hardware.

Usage recommendations

Use this direct attach cable for short-distance fixed links inside racks or between adjacent racks. Verify hardware compatibility and firmware support for passive DAC breakout cables before deployment. Avoid sharp bends, excessive tensile strain and exposure to sources of EMI. For longer distances or optical isolation requirements, consider active optical modules or fibre transceivers instead.
