Product information

Description

The BlueOptics 25GB-4-C05-QSFP28 InfiniBand fibre optic cable 5 m 4xSFP28 is a high-speed breakout cable designed for data center interconnects and high-performance computing environments. With a QSFP28 connector at one end and four SFP28 connectors at the other, this 5-metre multimode fibre assembly enables aggregation and distribution of four 25 Gbps lanes from a single QSFP28 port to four independent SFP28 ports, enabling flexible cabling for switches, servers and storage equipment while limiting signal loss over short to medium distances.

Advantages

This BlueOptics cable provides a compact, factory-terminated solution that reduces the need for separate transceivers and simplifies rack cabling. The breakout design offers predictable lane mapping and stable optical performance across all four channels. Constructed for data center use, the cable delivers low insertion loss and consistent transmission characteristics to support InfiniBand networking and other 25 Gbps applications.

Suitable for

  • Connecting QSFP28 ports to multiple SFP28 ports for server and switch interconnects
  • High-performance computing clusters and InfiniBand fabrics
  • Top-of-rack and end-of-row cabling in data centers
  • Short- to medium-reach 25 Gbps links where compact breakout cabling is required

Key specifications

  • Cable type: Multimode fibre breakout cable
  • Connector configuration: 1 × QSFP28 to 4 × SFP28
  • Length: 5 metres
  • Supported lane speed: 25 Gbps per SFP28 channel
  • Application: InfiniBand and 25 Gbps Ethernet-compatible interconnects
  • Typical characteristics: Low insertion loss, factory-terminated connectors

How to use

Identify the QSFP28 port on the source device and align the QSFP28 connector carefully before inserting to avoid damaging the transceiver ports. Route the cable to the target device(s) and connect the four SFP28 connectors to the corresponding SFP28 ports on switches, servers or NICs, ensuring correct lane mapping if required by your equipment. Secure cable runs to avoid excessive bending radii and mechanical strain; verify link status in your network equipment management interface after installation to confirm proper operation.

Usage recommendations

Maintain recommended bend radius for multimode fibre, avoid tight bends and kinks, and keep connector end faces clean using appropriate fibre cleaning tools. Use this cable for short- to medium-reach connections within racks and between adjacent racks; confirm compatibility with device port specifications and lane mapping requirements before deployment.
