BlueOptics CBL-QSFP-40GE-50M-F1-BO Cable de fibra óptica InfiniBand 50 m conector/ conector QSFP

The BlueOptics CBL-QSFP-40GE-50M-F1-BO is a 50 metre active InfiniBand fibre optic cable with QSFP Male to QSFP Male connections, designed for high-speed short-range optical links. Built to MSA-compliant QSFP to QSFP form factor and compatible with 40GBASE-SR4 protocols, this pre-assembled cable integrates transmitter and receiver modules on each end and uses multimode fibre to enable up to 40 Gbps data transfer over a 50 m link. The cable is intended for direct interconnect of switches, routers, storage systems and other compatible network hardware in data centre and enterprise environments and supports digital diagnostic monitoring for remote status and parameter readout where host equipment implements the DDM/DOM interface.

Advantages

The cable provides a factory-assembled optical connection that eliminates the need for separate transceivers and patching, reducing insertion points and potential loss. Conformance to MSA QSFP and 40GBASE-SR4 signalling ensures interoperability with equipment that supports the same standards. Integrated transmitter and receiver modules and the use of high-quality components aim to deliver stable optical performance, reduced electromagnetic susceptibility compared to copper links, and a long operational lifetime. Built-in digital diagnostic monitoring enables real-time readout of supply voltage, laser bias current, optical transmit and receive power and temperature when supported by the host device.

Suitable for

• Interconnect of QSFP-capable switches and routers within data centres
• Server and storage system uplinks requiring 40G short-range optical links
• High-bandwidth cluster and InfiniBand fabric connections up to 50 metres
• Environments requiring immunity to electromagnetic interference

Key specifications

• Connector type: QSFP Male to QSFP Male
• Length: 50 metres
• Supported data rate: up to 40 Gbps (40GBASE-SR4)
• Fibre type: multimode fibre (active optical cable with integrated transceivers)
• Form factor: QSFP-to-QSFP active optical cable (AOC), MSA compliant
• Diagnostics: Digital Diagnostic Monitoring / Digital Optical Monitoring (DDM/DOM) compliant with SFF-8472 when supported by host

How to use

Install the BlueOptics QSFP AOC by inserting each QSFP connector into the corresponding QSFP port on the network devices until the latch engages. Ensure host ports support QSFP and the 40GBASE-SR4 signalling mode required by your equipment. Verify that the cable routing avoids sharp bends and excessive tension to maintain optical performance. If your host hardware supports DDM/DOM, use the management interface or monitoring tools to read real-time diagnostics for link health and troubleshooting.

Recommendations

For reliable operation, handle the cable by the connector housings, maintain the minimum bend radius recommended for multimode AOCs, and confirm firmware or driver compatibility of the connected devices. Use this 50 m QSFP AOC for short-range 40G interconnects in racks and data hall deployments and validate DDM/DOM support on your equipment to access diagnostic data.
