Fiber Active Optical Cable BlueOptics QSFP-40G-AOC-20M 40GBASE-SR4, QSFP+ 20 m

The BlueOptics QSFP-40G-AOC-20M is an active optical cable (AOC) in QSFP+ form factor designed for 40GBASE-SR4 multimode connections over a 20 meter reach. It provides a single-cable direct-attach solution that integrates optical transceivers and fiber without separate modules, enabling 40 Gbps links between switches, servers and storage devices in data center environments. The cable supports multimode fiber signaling and is engineered to deliver stable short- to mid-range connectivity while simplifying rack-to-rack and switch-to-server interconnects.

Advantages

The integrated AOC design eliminates the need for separate transceiver modules, reducing component count and simplifying installation. As a QSFP+ 40G-rated cable, it ensures high bandwidth and consistent signal performance over a 20 m span appropriate for typical data center topologies. The pre-assembled cable reduces compatibility and handling issues associated with field-terminated fibers and helps maintain signal integrity through factory-aligned connectors and controlled optical paths.

Suitable for

• Rack-to-rack 40G interconnects in data centers
• Switch-to-switch and switch-to-server links requiring 40GBASE-SR4
• High-throughput storage and compute clusters within a single room or adjacent rooms
• Environments where easy, low-latency 40 Gbps connections are required without separate transceivers

Key specifications

• Form factor: QSFP+ (Quad Small Form-factor Pluggable Plus)
• Data rate: 40 Gbps aggregated
• Standard: 40GBASE-SR4 multimode
• Length: 20 m
• Medium: Active multimode optical cable (integrated transceivers and fiber)
• Connector type: QSFP+ to QSFP+ direct-attach optical connection
• Typical application: short- to mid-range data center interconnects

How to use

Install the BlueOptics QSFP-40G-AOC-20M by plugging the QSFP+ connectors into compatible 40G QSFP+ ports on your network devices. Ensure both endpoints support 40GBASE-SR4 signaling and that port firmware or vendor compatibility settings allow use of AOC cables. Route the cable within the rack or between racks following standard cable management practices to avoid sharp bends and mechanical stress. No separate transceivers or field termination are required; power and signaling are handled through the integrated modules.

Usage recommendations

Use the cable indoors within controlled data center environments, avoiding exposure to extreme temperatures, moisture, or direct sunlight. Maintain minimum bend radius recommendations from the manufacturer and keep connectors clean and protected when not in use. Verify device compatibility and port settings before deployment, and document cable endpoints for efficient troubleshooting and inventory management.
