Product information

Description

The BlueOptics CBL-520-BO InfiniBand fibre optic cable 20 m QSFP28 is a 20-metre Active Optical Cable (AOC) with male QSFP28 connectors on both ends. It is designed for high-speed data transmission over multimode fiber and supports 100G-class short-reach optical links commonly used in data centers, switches, routers and storage systems. The integrated transmitter and receiver modules at each end convert electrical signals to optical signals and back, providing a pre-assembled fibre connection without the need for separate patch cords or transceivers.

Advantages

The cable offers low signal loss and immunity to electromagnetic interference due to its fibre-optic construction, enabling stable high-bandwidth connections. As an AOC with QSFP28 interfaces, it supports simultaneous send and receive operation and complies with common MSA connection standards for QSFP28 to QSFP28 links. Built using tested optical and electronic components, the cable aims to provide extended operational life and predictable performance for installed optical links.

Suitable for

  • 100G short-reach interconnects between QSFP28 ports in switches and routers
  • High-speed links in data center top-of-rack and spine architectures
  • Connections between storage systems and host adapters requiring InfiniBand or Ethernet at 100G-class rates
  • Environments where immunity to EMI and reduced cabling complexity are required

Key specifications

  • Cable type: Active Optical Cable (AOC) with multimode fibre
  • Length: 20 metres
  • Connector type: QSFP28 male on both ends (QSFP28 to QSFP28)
  • Supported data rate: up to 100 Gbit/s per link (100G-class short-reach)
  • Transmission: simultaneous transmit and receive via optical laser modules
  • Monitoring: supports digital diagnostics / digital optical monitoring (DDM/DOM) where supported by host hardware

How to use

Install the BlueOptics CBL-520-BO by inserting each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring correct orientation and secure seating. Verify that connected hardware supports QSFP28 AOCs and, if required, the cable's DDM/DOM functionality for monitoring. Use the cable as a direct interconnect—no separate transceivers, patch panels or additional fibre polishing are necessary. After connection, check link status on the host devices and confirm negotiated data rates and link health.

Lietošanas ieteikumi

When routing, avoid tight bends and excessive tension; maintain minimum bend radius as specified by multimode fibre practice, keep connectors clean and protect unused ends with dust caps. If diagnostics are required, confirm host support for DDM/DOM to access real-time optical parameters.
