## Summary description

The BlueOptics ET7502-AOC-3M-BO is a 3-meter InfiniBand fibre optic cable with QSFP-DD connectors. It features male-to-male connectors, ensuring high-speed data transfer and reliable performance for data centers and high-performance computing environments.

## Long description

The BlueOptics ET7502-AOC-3M-BO InfiniBand fibre optic cable 3m QSFP-DD Male/Male is a 3‑meter active optical cable designed for high-density data center and high-performance computing environments. It features QSFP‑DD male connectors on both ends and uses multi‑mode fibre with integrated transmitter and receiver modules to carry optical signals for InfiniBand and compatible 400GBASE-SR8 or other high‑speed protocols where QSFP‑DD interfaces are supported.
Advantages
This QSFP‑DD AOC offers a compact, low-latency connection with consistent optical performance across its 3 m length. The integrated transceiver design eliminates separate SFP/QSFP modules, reducing component count and simplifying rack cabling. It is intended for direct-mate, high-throughput links between QSFP‑DD ports in switches, routers, storage systems and compute nodes that support QSFP‑DD AOC connectivity.
Suitable for
 High-performance computing clusters and InfiniBand fabrics
 400G data center uplinks and spine-to-leaf connections
 Interconnects between switches, routers and storage appliances with QSFP‑DD ports
 Short-reach, high-bandwidth connections inside racks or between adjacent racks
Key specifications
 Connector type: QSFP‑DD male to QSFP‑DD male
 Cable type: Active Optical Cable (AOC) with integrated transmitter and receiver
 Length: 3 meters
 Supported protocols: InfiniBand and compatible with 400GBASE‑SR8 and similar high‑speed link protocols where QSFP‑DD is used
 Fiber: multi‑mode optical fiber for short‑reach, high‑bandwidth links
How to use
Install the cable by inserting each QSFP‑DD connector into the matching QSFP‑DD port on your devices until it latches. Ensure that connected devices are powered down or follow hot‑swap procedures recommended by the device vendor. Verify that your switches, routers or hosts support QSFP‑DD AOC modules and the intended protocol (InfiniBand, 400G Ethernet modes, etc.). After connection, confirm link status and speed via device management interfaces and monitor for any error counters during initial operation.
Usage recommendations
Use this 3 m QSFP‑DD AOC in short‑reach topologies such as within racks or between adjacent racks. Verify compatibility with your hardware vendor’s support list before deployment, handle connectors by the housing to avoid contamination, and keep dust caps on unused ports. For stable high‑speed operation, maintain bend radius limits for the cable and avoid excessive tension or tight cable management routing.
