Cavo in fibra ottica InfiniBand BlueOptics XLAOCBL3-BO 3 m QSFP

The BlueOptics XLAOCBL3-BO InfiniBand fibre optic cable 3 m QSFP is a 3-metre active optical cable (AOC) with QSFP-to-QSFP male connectors designed for high-speed 40G interconnects. It implements multimode optical transmission and is compatible with platforms that support QSFP 40GBASE-SR4 and InfiniBand QSFP AOC connections. The pre-assembled cable integrates optical transmitters and receivers in the QSFP modules to provide a plug-and-play fibre link without the need for separate transceivers or patching.

Advantages

This BlueOptics 3 m QSFP AOC offers electrical and mechanical compliance with QSFP AOC MSA profiles and is designed to deliver stable 40 Gbps-class connectivity over a short multimode link. The integrated design reduces installation time and minimizes connector cleaning and insertion losses typical of patch-cord assemblies. Built according to industrial quality standards, the cable includes digital diagnostic monitoring (DDM/DOM) functionality for remote monitoring of supply voltage, laser bias current, output and input power and module temperature where host hardware supports these features.

Suitable for

• Server-to-switch or switch-to-switch short-range links in data centres
• High-performance computing (HPC) clusters and InfiniBand fabric interconnects
• Storage system connections and SAN aggregation within rack or adjacent racks
• Environments requiring plug-and-play 40G QSFP optical links without separate transceivers

Key specifications

• Cable type: Active Optical Cable (AOC) with QSFP-to-QSFP connectors
• Nominal length: 3 metres
• Supported link standard: 40G (40GBASE-SR4 / InfiniBand QSFP-class short-range)
• Optical medium: Multimode fibre within the AOC assembly
• Monitoring: Digital Diagnostic Monitoring (DDM/DOM) support if host system provides access
• Application: Short-reach data centre interconnects, HPC and storage fabrics

How to use

Install the BlueOptics XLAOCBL3-BO by inserting each QSFP connector into the corresponding QSFP port on host devices while the devices are powered down or following your equipment vendor's hot-plug guidance. Ensure QSFP cages are accessible and aligned, avoid sharp bends in the fitted cable and secure the cable to prevent strain on the connectors. Verify that the connected hardware supports QSFP AOC modules and, if required, enable or check digital diagnostics via the host management interface to monitor optical parameters.

Recommendations

Use the cable within recommended bend radius limits, avoid exposure to excessive mechanical stress or contaminating the connector interfaces, and confirm host compatibility with QSFP AOC modules and DDM/DOM features to ensure full functionality and monitoring capability.
