InfiniBand/fibre optic cable BlueOptics CBL-0310-003-BO 3 m QSFP Male/Male

The BlueOptics CBL-0310-003-BO is a 3 m InfiniBand/fibre optic cable with QSFP male connectors on both ends, engineered for high-speed data transmission in data centers and networking environments. This active optical cable (AOC) implements QSFP-to-QSFP connectivity and is compatible with 40GBASE-SR4 applications, supporting multi-mode fibre transmission with integrated transmitters and receivers at each end. The cable is intended for use where reliable 40 Gbit/s links are required between switches, routers, storage systems and other QSFP-enabled equipment.

Advantages

The cable provides a standardized QSFP male-to-male connection that simplifies short-reach high-bandwidth links while maintaining signal integrity through active optical components. Its 3 m length offers flexibility for rack-to-rack and chassis-to-chassis connections without the electrical limitations of direct-attach copper. Compatibility with common 40G SR4 protocols ensures predictable performance in Ethernet, Fibre Channel over Ethernet and SDH/SONET environments where multi-mode AOC solutions are supported.

Suitable for

• High-speed interconnects between QSFP-enabled switches and routers
• Connections between storage systems and network devices supporting 40G
• Short-reach data center links using multi-mode fibre
• Environments requiring QSFP-to-QSFP active optical cabling

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 3 metres
• Transmission type: Active Optical Cable (AOC) for multi-mode fibre
• Data rate support: up to 40 Gbit/s (40GBASE-SR4 compatible)
• Typical applications: Ethernet, Fibre Channel over Ethernet, SDH/SONET up to 40G

How to use

Install the BlueOptics QSFP AOC by inserting each QSFP connector into the corresponding QSFP port on your devices until the latch secures. Ensure both endpoints are QSFP-enabled and configured for the intended 40G protocol. No separate transceiver modules are required because the cable contains integrated optical transmitters and receivers. After connection, verify link status and speed through device management interfaces and, if necessary, adjust interface settings to match the expected 40G mode and lane configuration.

Usage recommendations

Use the cable for short-range rack or chassis interconnects where multi-mode AOC is supported and avoid tight bends or kinks; follow manufacturer guidance for minimum bend radius and handling to preserve optical performance. Confirm device compatibility with QSFP AOC modules and, for large deployments, validate interoperability in a test environment before wide-scale installation.
