BlueOptics CBL-505-BO InfiniBand/fibre optic cable 5 m QSFP28 Aqua

The BlueOptics CBL-505-BO InfiniBand/fibre optic cable 5 m QSFP28 Aqua is a 5-metre active optical cable (AOC) with QSFP28 male-to-male connectors designed for high-speed short-reach links in data centres and networking equipment. The cable uses multi-mode optical transmission and complies with QSFP28 physical interface standards to support 100G-class applications such as 100GBASE-SR4, enabling simultaneous transmit and receive channels over fiber without copper patching.

Advantages

This BlueOptics QSFP28 AOC provides plug-and-play connectivity with pre-assembled optical terminations that eliminate the need for field splicing or patch cords, reducing insertion loss and maintenance. The design includes transmitter and receiver modules on each end to handle optical signalling for Ethernet and related high-speed protocols. The cable is manufactured according to established MSA guidelines and is compatible with hardware platforms that support QSFP28 100G AOCs, offering a compact, low-latency solution for short-distance, high-bandwidth interconnects.

Suitable for

• 100G short-reach links between switches and routers in data centres
• High-speed interconnects for storage systems and server uplinks
• InfiniBand or fibre-optic links requiring QSFP28 interfaces
• Environments where electromagnetic immunity and low latency are required

Key specifications

• Length: 5 metres
• Connector type: QSFP28 male to QSFP28 male (AOC)
• Transmission medium: Multi-mode fiber (active optical cable)
• Supported data rates: Designed for 100G-class applications (e.g., 100GBASE-SR4)
• Cable colour: Aqua (multimode convention)

How to use

Install the BlueOptics CBL-505-BO by inserting each QSFP28 connector into the corresponding QSFP28 ports on your switches, routers or servers while the devices are powered according to vendor guidelines. No additional transceivers or patching is required; the AOC handles optical transmission through integrated transmitter and receiver modules. Verify that the host hardware supports QSFP28 AOCs and, if necessary, enable or confirm link settings in the device operating system or management interface. For monitoring, enable DOM/DDM support on compatible hardware if diagnostics are required.

Usage recommendations

Handle the cable by the connector housings and avoid tight bends; adhere to the manufacturer’s minimum bend radius and equipment port insertion/removal procedures. Confirm hardware compatibility with QSFP28 AOCs before deployment and, where available, use the digital diagnostic monitoring (DDM/DOM) features of the host to observe transmit/receive power and temperature for proactive maintenance.
