Product information

Description

The BlueOptics 49Y7889-BL is a 5 m InfiniBand/fibre optic direct attach cable with a QSFP connector on one end and four SFP+ interfaces on the other. Designed for short-range high-speed connections in racks and between adjacent racks, this passive DAC (Direct Attach Cable) supports aggregated 40 Gbit/s links via a 4x10G configuration and is compatible with systems that accept QSFP-to-4xSFP+ passive twinax connections.

Advantages

This 5 m QSFP to 4xSFP+ cable provides a compact solution for high-throughput interconnects with low latency and low power consumption. Its passive twinax design requires no active electronics for 10G lanes when used with compatible ports, resulting in reduced failure points and lower operational power draw. Manufactured to MSA-compliant dimensions and assembled from established component vendors, the cable is intended to offer reliable year-round operation and simplified rack-level cabling.

Suitable for

  • Connecting QSFP-enabled switches or adapters to multiple SFP+ ports within the same rack or adjacent racks
  • 40GBase-CR4 and 4x10GBase-CR short-reach interconnects
  • High-throughput links for Ethernet, FCoE and InfiniBand within data centre topologies

Key specifications

  • Cable length: 5 m
  • Connector type: QSFP (one end) to 4 × SFP+ (other end)
  • Data rate: aggregate up to 40 Gbit/s (4 × 10 Gbit/s lanes)
  • Cable type: passive twinax copper
  • Gauge: 26 AWG
  • Standard compliance: MSA-compliant QSFP/SFP+ mechanical interface dimensions

How to use

Install the cable by inserting the QSFP plug into the QSFP port of the source device and the four SFP+ plugs into the corresponding SFP+ ports of the destination device, ensuring proper orientation and full seating of each connector. Use this passive DAC where the hardware and firmware explicitly support passive QSFP-to-4xSFP+ direct attach cables and the intended transmission protocol. Avoid sharp bends near the connector ends, secure any strain relief, and confirm link status via the connected devices' interface indicators or management system.

Usage recommendations

For reliable operation, verify compatibility with the target switch, router or storage platform before deployment and test a single cable in your environment if possible. Install within racks or between adjacent racks to remain within the recommended short-reach distance and keep the cable route free from excessive mechanical stress or sources of electromagnetic interference.
