Product information

Description

The BlueOptics InfiniBand/fibre optic cable 3 m QSFP28 Black is a 3-metre high-speed connection cable designed for data centre and high-performance networking environments. Equipped with QSFP28 male-to-male connectors, this cable supports high bandwidth InfiniBand and fibre optic links and is intended for short-range, low-latency interconnects between switches, servers and host adapters. The cable’s black jacket provides a discreet appearance while offering protection for the fibre elements inside.

Advantages

This 3 m QSFP28 cable delivers reliable high-bandwidth data transfer with low latency suitable for InfiniBand fabric and fibre optic networks. Male-to-male QSFP28 terminations ensure compatibility with QSFP28 ports used in modern networking equipment. The cable’s design focuses on signal integrity and consistent performance across short rack-to-rack or in-rack connections, while the robust outer jacket provides mechanical protection and easy handling during installation.

Suitable for

  • High-performance computing clusters and InfiniBand fabrics
  • Server-to-switch and switch-to-switch short-range links
  • Data centre rack interconnects and top-of-rack connections
  • Low-latency storage area network (SAN) and RDMA setups

Key specifications

  • Cable length: 3 m
  • Connector type: QSFP28 male-to-male
  • Cable colour: Black
  • Transmission medium: Fibre optic suitable for InfiniBand
  • Designed for short-range, high-bandwidth, low-latency connections

How to use

Connect each QSFP28 male connector to the corresponding QSFP28 ports on your networking devices, ensuring connectors are aligned and fully seated. Use the cable for direct links between compatible ports in servers, switches or host adapters. Avoid tight bends and kinks; maintain recommended bend radii for fibre optic cables and route the cable to prevent excessive strain on connectors. Verify link status on devices after connection to confirm proper operation.

Usage recommendations

For optimal performance, install the cable in rack or cabinet environments with minimal bend and secure routing. Keep dust caps on connectors when not in use, and inspect connectors for contamination before mating. Use this cable for short-range, high-bandwidth applications and consult equipment documentation for port compatibility and firmware or driver requirements.
