AOC Cable BlueOptics AOC-Q-Q-40G-7M-CT-BO 7m QSFP Male/Male

The BlueOptics AOC-Q-Q-40G-7M-CT-BO is a 7-meter active optical cable with QSFP male connectors on both ends, designed for high-speed data transmission in data centers and network environments. Compliant with 40GBASE-SR4 applications, this AOC integrates optical transmitters and receivers at each connector to carry multi-mode optical signals and supports 40 Gbit/s links over a short-reach multimode fiber connection. It is intended for linking QSFP-enabled switches, routers and servers where reliable, low-latency connectivity is required.

Advantages

The cable provides a direct QSFP-to-QSFP connection without the need for separate transceivers, reducing rack space and simplifying installations. As an active optical cable, it delivers electrical isolation and lower electromagnetic interference compared with copper alternatives while enabling 40 Gbit/s throughput over a 7 m reach. Its QSFP form factor follows industry MSA conventions for compatibility with QSFP ports on supported networking equipment.

Suitable for

• Interconnects between QSFP ports on data center switches
• Server-to-switch high-speed links within racks or adjacent racks
• Short-reach 40GBASE-SR4 applications in multi-vendor environments

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP male to QSFP male
• Nominal data rate: up to 40 Gbit/s
• Length: 7 meters
• Optical medium: multimode fiber with integrated transceivers at each end
• Application: short-reach 40GBASE-SR4 and similar high-speed protocols

How to use

Power down or place networking equipment into a hot-plug-supported state according to the vendor’s instructions if required, then insert each QSFP connector into the appropriate QSFP port until it seats securely. Ensure port settings and link negotiation on connected devices are configured for 40G operation or the intended protocol (for example, Ethernet or Fibre Channel over Ethernet). Monitor link status indicators on both ends to confirm a successful connection. Follow equipment vendor guidelines for hot-plugging if you intend to insert or remove the cable while devices are powered.

Recommendations

Avoid sharp bends and excessive pulling force on the cable; maintain the manufacturer’s minimum bend radius for multimode fiber. Keep connectors clean and protected when not in use to prevent contamination. Verify device compatibility with QSFP AOC modules and, if using hardware from different vendors, consult interoperability lists or perform a test before deployment in critical systems.
