## Summary description

The BlueOptics 740-090165-BO is a 3 m InfiniBand/fibre optic cable featuring QSFP-DD connectors. It provides high-speed data transfer with male/male connectors, ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics 740-090165-BO InfiniBand/fibre optic cable is a 3 m active optical cable (AOC) with QSFP-DD Male to QSFP-DD Male connectors. Designed for high-density data center and high-performance computing environments, this 400G-capable multimode fibre AOC provides optical transceivers integrated at both ends to enable reliable short-reach links between compatible QSFP-DD ports. The cable follows MSA guidelines and is compatible with systems that support QSFP-DD 400GBASE-SR8 connections.
Advantages
This 3 m BlueOptics AOC offers high aggregate bandwidth up to 400 Gbit/s over multimode fibre, low latency due to direct optical transmission, and plug-and-play QSFP-DD male connectors for straightforward installation. Integrated transmitter and receiver modules at each connector eliminate the need for separate SFP modules and simplify cabling management in dense rack and switch topologies. The fixed-length AOC reduces signal loss compared with equivalent copper assemblies for short-reach applications.
Suitable for
High-performance computing clusters and interconnects
Data centre spine and leaf switch connections
High-speed storage area network uplinks and aggregation
Server-to-switch short-reach fiber links within racks
Key specifications
Connector type: QSFP-DD Male to QSFP-DD Male
Cable type: Active Optical Cable (AOC), multimode fibre with integrated transceivers
Length: 3 meters
Supported link standard: 400GBASE-SR8 (400 Gbit/s short-reach multimode)
Typical applications: Ethernet, Fibre Channel over Ethernet, and SDH/SONET high-speed transport
How to use
Ensure both devices have compatible QSFP-DD ports and support the 400GBASE-SR8 or equivalent QSFP-DD AOC interface. With the host equipment powered down or in accordance with the vendor’s hot-plug guidance, align the QSFP-DD connector of the AOC with the port and insert until it seats securely. Follow the system vendor’s instructions for link configuration and verify link status in the host management interface. No additional transceiver modules are required; the cable presents as an integrated optical interface to supported devices.
Usage recommendations
Install and remove the cable using the connector bail or pull-tab to avoid stressing the fibre assembly. Use the 3 m length for short-reach connections inside racks or across adjacent racks; for longer distances consult multimode fibre link budgets and system vendor compatibility lists. Verify device compatibility with QSFP-DD 400G AOC support to ensure proper operation.
