BlueOptics QSFP-40G-3M-RC-BO InfiniBand Fibre Optic Cable 3m OSFP QSFP Male/Male

The BlueOptics QSFP-40G-3M-RC-BO InfiniBand Fibre Optic Cable 3m OSFP QSFP Male/Male is a 3-meter active optical cable (AOC) designed for high-speed short-reach connections. It features QSFP-compatible terminations and an OSFP-compatible form factor, enabling 40G data transmission over multimode fibre for use in data centers and network equipment. The cable integrates optical transmitter and receiver modules on each end to support standard 40GBASE-SR4 class links and to ensure signal integrity across the 3 m link length.

Advantages

This BlueOptics AOC provides a compact, low-latency link for server, switch and storage interconnects without the need for separate transceivers and fibre patch cords. The integrated transmitter/receiver design reduces component count and simplifies installation while maintaining compatibility with equipment that supports QSFP/OSFP 40G SR4 interfaces. The 3 m length is suitable for short-reach rack-to-rack or within-rack connections and offers consistent optical performance for Ethernet, Fibre Channel over Ethernet and other high-speed protocols up to 40 Gbps.

How to use

Insert each male QSFP/OSFP end into compatible QSFP/OSFP ports on the equipment until the connector latches. Ensure ports on switches, routers or storage devices are powered down or follow hot‑plug guidelines provided by the device manufacturer if inserting while powered. After seating the cable, verify link status and speed through the device management interface and confirm the 40G link is negotiated. If a device restricts third-party AOCs, enable any vendor-specific compatibility settings required by the host equipment.

Recommendations

Use this 3 m active optical cable for short-reach connections inside racks or between adjacent racks. Avoid tight bends and maintain the manufacturer’s minimum bend radius for multimode fibre. Verify compatibility with your hardware platform and firmware, and if necessary request a test sample to confirm interoperability before large deployments.
