BlueOptics OC40-QSFP-AOC-7M-C-BO InfiniBand fibre optic cable 7m QSFP Male/Male

The BlueOptics OC40-QSFP-AOC-7M-C-BO is a 7-metre active optical cable (AOC) with QSFP male-to-male connectors designed for high-speed InfiniBand and 40GBASE-SR4 connections in data centers and networking environments. The cable integrates transmitters and receivers in the QSFP housings and uses multimode optical transmission to deliver up to 40 Gbit/s over a 7 m link, providing a compact, passive-cable alternative to transceiver modules where compatible QSFP ports are available.

Advantages

This AOC provides a single-cable solution that combines QSFP-to-QSFP connectivity with integrated optical transceivers, reducing the need for separate transceiver modules and fibre patching. Its 7-metre length offers flexible rack-to-rack or shelf-to-shelf connections within server rooms and equipment cabinets. The cable is compatible with hardware that supports the referenced 40GBASE-SR4 QSFP form factor and supports common high-speed protocols such as Ethernet and Fibre Channel over Ethernet.

Suitable for

• Rack-to-rack and shelf-to-shelf connections in data centers
• Interconnecting switches, routers and storage systems with QSFP ports
• High-throughput links requiring 40 Gbit/s short-reach optical connectivity

Key specifications

• Connector type: QSFP male to QSFP male
• Cable type: Active optical cable (AOC) with multimode optical transmission
• Nominal data rate: up to 40 Gbit/s
• Standard compatibility: 40GBASE-SR4 / QSFP MSA form factor
• Length: 7 metres

How to use

Insert each QSFP connector into the corresponding QSFP port of the devices to be connected, ensuring the latch engages and the connector is fully seated. Verify both devices support the QSFP AOC and the 40GBASE-SR4 or InfiniBand protocol in use. After installation, confirm link status and data rate through the devices' management interfaces and monitor for any link errors. Remove the cable by releasing the connector latch and carefully withdrawing the QSFP plug.

Recommendations

Use the cable for short-reach high-speed links within racks or between adjacent racks; avoid tight bends and excessive pulling force. Ensure connected equipment explicitly supports QSFP AOC compatibility and the required 40G protocols to prevent link negotiation issues.
