BlueOptics QSFP-H40G-AOC1M-AL-BO InfiniBand fibre optic cable 1 m

The BlueOptics QSFP-H40G-AOC1M-AL-BO InfiniBand fibre optic cable 1 m is a 1‑metre active optical cable (AOC) with QSFP male connectors on both ends, designed for short-reach, high-speed interconnects in data centers and high-performance computing environments. It implements the 40GBASE-SR4 transmission concept over multimode optical fiber and includes integrated transmitter and receiver modules at each end to convert electrical QSFP signals to optical form and back. The cable is intended for direct QSFP-to-QSFP connections between switches, servers, storage systems and other networking hardware that support QSFP-based 40 Gbit/s links.

Advantages

The cable provides a compact, low-latency direct connection that removes the need for separate transceivers and patch cords for short distances. Built to the QSFP form-factor and MSA-compatible electrical/optical interface, it supports standardized 40 Gbit/s short-range multimode operation while simplifying port density and cabling management in racks and switch stacks. Integrated optical conversion reduces connector count and potential insertion loss compared with discrete transceiver plus MPO trunk solutions.

Suitable for

• Short-reach 40 Gbit/s interconnects in data center top-of-rack and leaf-spine deployments
• Direct QSFP-to-QSFP links between switches, routers and server NICs
• High-performance computing clusters and InfiniBand fabrics requiring low-latency links
• Connections between storage systems and aggregation switches supporting 40G

Key specifications

• Connector type: QSFP male to QSFP male
• Cable type: Active optical cable (AOC) with integrated transmitter and receiver
• Data rate: up to 40 Gbit/s aggregate
• Transmission standard: 40GBASE-SR4 multimode operation
• Length: 1 metre
• Low-latency design suitable for InfiniBand and Ethernet fabrics

How to use

Ensure both QSFP ports on the devices to be connected support 40G QSFP modules and are powered off or in a safe state according to your equipment vendor’s guidelines before insertion. Align the QSFP housings with the port and insert the cable until the connector latches. After powering up, verify link status and negotiated speed through the device management interface or LED indicators. For removal, release the latch mechanism and pull the connector straight out to avoid stressing the cable or port.

Recommendations

Use the cable for short-reach connections within a single rack or between adjacent racks; avoid tight bends and maintain the manufacturer’s minimum bend radius for multimode AOC assemblies. Match multimode fiber grades and switch firmware compatibility where vendor interoperability is required. For critical deployments, test the link in your environment to confirm full operational compatibility and expected throughput.
