BlueOptics CBL-QSFP-40GE-1M-F1-BO InfiniBand/fibre optic cable 1m Male/Male

The BlueOptics CBL-QSFP-40GE-1M-F1-BO InfiniBand/fibre optic cable is a 1 metre active optical cable (AOC) with QSFP connectors on both ends. Designed for 40GBASE-SR4 applications, this male-to-male cable carries optical signals over multimode fibre and is intended for short-reach, high-speed interconnects in data centres and high-performance computing environments. The cable integrates transmitter and receiver modules at each end to support reliable 40 Gbit/s links between compatible QSFP ports.

Advantages

This BlueOptics AOC provides a compact, low-latency alternative to transceiver-plus-patch-cord setups by combining optics and fibre within a single assembly. Compliance with QSFP form-factor and MSA-aligned electrical/optical interfaces ensures broad interoperability with network equipment that supports 40GBASE-SR4. The 1 m length reduces excess cable slack in rack and chassis connections and simplifies cable management while supporting multi-protocol traffic such as Ethernet and Fibre Channel over Ethernet at line rates up to 40 Gbit/s.

Suitable for

• Short-reach 40 Gbit/s links between QSFP ports in data centre switches and routers
• Interconnects in high-performance computing clusters and storage arrays
• Top-of-rack and adjacent-rack connections where a 1 m optical link is sufficient
• Environments requiring low-latency, high-bandwidth fibre connections

Key specifications

• Connector type: QSFP male to QSFP male (both ends)
• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Data rate: supports up to 40 Gbit/s aggregate
• Application standard: 40GBASE-SR4 multi-mode operation
• Length: 1 metre
• Fibre: multimode optical fibre within the assembly

How to use

Install the cable by aligning each QSFP connector with the corresponding QSFP port on your networking devices and inserting until the latch engages. Ensure both devices support 40GBASE-SR4 or compatible QSFP AOC operation. Route the 1 m cable to avoid sharp bends and mechanical strain; maintain the recommended minimum bend radius for multimode AOCs. No separate transceivers or fibre patch cords are required when using this integrated AOC solution.

Recommendations

Use this 1 m BlueOptics QSFP AOC for short, direct connections in racks or between adjacent equipment. Verify device compatibility with 40G QSFP AOC modules and keep connectors clean during installation. For longer distances or single-mode requirements, select a cable or transceiver solution designed for those use cases.
