Product information

Description

The BlueOptics QFX-Q-S-DAC-5M InfiniBand fibre optic cable QSFP28 4xSFP28 5m is a 5‑metre direct attach cable with a QSFP28 plug on one end and four SFP28 plugs on the other. Designed for high‑density networking environments, it supports high‑speed data transmission between switches, servers and host adapters. The cable’s male‑to‑male configuration offers straightforward, tool‑free installation and is intended for short‑reach links within racks and between adjacent racks in data centres.

Advantages

This cable provides a compact connection solution that consolidates four SFP28 links into a single QSFP28 interface, reducing cabling complexity and saving rack space. It is suitable for low‑latency, high‑throughput environments and is built to industry connector form‑factors for broad compatibility with InfiniBand and Ethernet equipment that use QSFP28 and SFP28 interfaces. The 5‑metre length balances reach and signal integrity for typical in‑rack and top‑of‑rack deployments.

Suitable for

  • High‑speed server‑to‑switch or switch‑to‑switch interconnects in data centres
  • Top‑of‑rack and middle‑of‑row short‑reach links
  • High‑performance computing (HPC) clusters using InfiniBand or 100GbE breakouts
  • Environments requiring consolidation of four 25Gb/s lanes into one 100Gb/s QSFP28 port

Key specifications

  • Cable type: Direct attach cable with QSFP28 to 4×SFP28
  • Length: 5 metres
  • Connector configuration: one QSFP28 (male) to four SFP28 (male)
  • Supported protocols: InfiniBand and compatible high‑speed Ethernet breakouts (e.g., 100GbE via 4×25Gb/s lanes)
  • Use case: short‑reach, in‑rack and adjacent‑rack connections

How to use

Align the QSFP28 connector with the QSFP28 port and the SFP28 connectors with their respective SFP28 ports, then insert gently until each connector latches. Ensure devices are powered and ports are enabled according to the host equipment’s configuration. For breakout usage, configure the QSFP28 port on the switch or adapter to operate in 4×25Gb/s mode if required by the hardware and firmware. Avoid excessive bending or crushing of the cable during routing to maintain signal integrity.

Usage recommendations

Install the cable in environments with controlled airflow and secure the cable to prevent strain on connectors. Verify compatibility and required port modes with device documentation before deployment, and route the cable to minimize sharp bends and mechanical stress for reliable long‑term operation.
