Product information

Description

The BlueOptics Q+BC0003-S+-BL InfiniBand/fibre optic cable is a 3 m direct attach cable (DAC) with a QSFP connector on one end and four SFP+ connectors on the other end. Designed for short-range high-speed links in racks and between adjacent racks, this passive twinax copper-style cable supports aggregated 40 Gbit/s connectivity (4x10 Gbit/s) and is suitable for InfiniBand and Ethernet applications where compatible hardware accepts QSFP-to-4xSFP+ DACs.

Advantages

This 3 m QSFP-to-4xSFP+ cable provides a compact and low-latency connection option for data center and network equipment. As a passive direct attach solution, it consumes minimal power, simplifies installation by avoiding transceivers, and offers predictable performance over short distances. The cable is manufactured to industry MSA guidelines and is intended to be compatible with hardware platforms that support equivalent QSFP-to-4xSFP+ DAC modules.

Suitable for

  • High-speed links between switches inside a rack or between adjacent racks
  • Connecting QSFP ports to multiple SFP+ ports for 4x10G aggregation
  • InfiniBand and Ethernet environments requiring short-range 40G connectivity
  • Storage systems, routers, and servers that accept passive QSFP-to-4xSFP+ DACs

Key specifications

  • Cable length: 3 m
  • Connector types: QSFP (one end) and 4× SFP+ (other end)
  • Aggregate data rate: up to 40 Gbit/s (4×10 Gbit/s)
  • Cable type: passive direct attach twinax-style cable suitable for short-distance electrical signaling
  • Wire gauge: 30 AWG (as a twinax copper implementation)
  • Standards: designed for 40GBase-CR4 / 4x10GBASE-CR applications and MSA-compliant form factor

How to use

Install the cable by plugging the QSFP connector into a compatible QSFP port and connecting the four SFP+ plugs into the target SFP+ ports. Ensure both ends are securely seated and that the host devices support passive QSFP-to-4xSFP+ direct attach cables for the intended protocol (Ethernet, FCoE or InfiniBand). Use the cable for short-distance links within racks or between adjacent racks; avoid routing it over long runs where active transceivers or fiber would be required.

Usage recommendations

Verify compatibility with your switch, router or storage platform before installation. Keep the cable within its 3 m specification, maintain gentle bend radii to avoid strain on the connectors and contacts, and avoid exposure to excessive heat or mechanical stress to preserve long-term reliability.
