InfiniBand/optický kabel BlueOptics 3 m QSFP samec/samec 740-065051-BO

The BlueOptics InfiniBand/fibre optic cable 3 m QSFP Male/Male 740-065051-BO is a 3 metre active optical cable (AOC) with QSFP-to-QSFP male connectors, designed for high-speed short-reach interconnects in data centres and networking environments. It implements a 40GBASE-SR4 compatible AOC topology with integrated transmitter and receiver electronics at each end and is intended for use with hardware platforms that support QSFP 40 Gbps optical links. The cable uses multi-mode fibre and supports simultaneous send and receive operation over optical lasers for low-latency, high-bandwidth connections.

Advantages

The cable provides a factory-assembled optical connection that eliminates the need for separate patch cords and reduces connector cleaning and attenuation concerns. Built to MSA-compatible QSFP specifications, it includes integrated transceivers on both ends to simplify installation and ensure protocol-aware operation for Ethernet, Fibre Channel over Ethernet or SDH/SONET applications up to 40 Gbps. The active optical design reduces susceptibility to electromagnetic interference and offers predictable signal quality over the 3 m length.

Suitable for

• Short-reach links between QSFP ports in switches and routers within racks and between adjacent racks
• High-speed server-to-switch and switch-to-switch connections in data centres
• Storage system interconnects and SAN uplinks that require 40 Gbps optical links

Key specifications

• Length: 3 metres
• Connector type: QSFP male to QSFP male
• Type: Active Optical Cable (AOC)
• Data rate: up to 40 Gbps per link (40GBASE-SR4 compatible)
• Fibre: multi-mode optical fibre
• Supports digital diagnostics (DDM/DOM) for real-time monitoring when supported by host hardware

How to use

Install the BlueOptics QSFP AOC by inserting each QSFP male connector into the corresponding QSFP port on the devices to be linked, ensuring proper seating and latching. Verify that the host hardware and firmware support QSFP 40G AOC modules and, if desired, enable digital diagnostics on supported platforms to monitor voltage, temperature and optical power parameters. No field termination or patching is required; route the pre-assembled cable to avoid sharp bends and mechanical strain and ensure the optical path remains free from kinks.

Recommendations

For reliable operation, avoid tight bends and mechanical stress on the cable, confirm host compatibility with QSFP 40G AOCs before deployment, and use the DDM/DOM monitoring functions where available to aid diagnostics and preventive maintenance.
