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

The BlueOptics QSFP-H40G-AOC1M-AT-BO is a 1 m Active Optical Cable (AOC) with QSFP+ connectors on both ends, designed for InfiniBand and 40GBASE-SR4 applications. It provides a pre-terminated optical link that integrates transmitter and receiver electronics in the connectors and uses multimode fiber to transmit up to 40 Gbit/s over short distances. The cable is manufactured to MSA-compliant QSFP AOC specifications and is intended for use in data center switching, routing, and storage interconnects where a reliable, low-latency optical connection is required.

Advantages

The cable offers a factory-assembled optical connection that eliminates patching and reduces insertion loss associated with separate transceivers and patch cords. Built to MSA standards, it supports digital diagnostics monitoring (DDM/DOM) for real-time information such as supply voltage, laser bias current, optical transmit and receive power, and temperature. Components from established suppliers are used in production to achieve long operating life and consistent signal integrity. The QSFP to QSFP form factor enables simultaneous send and receive channels, supporting Ethernet, Fibre Channel over Ethernet (FCoE) and SDH/SONET protocols up to 40 Gbit/s on 1 m multimode links.

Suitable for

• Short-reach server-to-switch and switch-to-switch connections in data centers
• High-performance computing and InfiniBand interconnects
• Storage area network (SAN) backbones and aggregation links
• Environments requiring low-latency, high-bandwidth optical links

Key specifications

• Connector type: QSFP (QSFP to QSFP)
• Length: 1 meter
• Supported data rate: up to 40 Gbit/s aggregate
• Transmission medium: multimode fiber (active optical cable)
• Protocol support: 40GBASE-SR4, InfiniBand and compatible high-speed protocols
• Monitoring: Digital Diagnostics Monitoring (DDM/DOM) compliant with SFF-8472
• Standard compliance: MSA QSFP AOC mechanical and electrical specifications

How to use

Insert each QSFP connector into the appropriate QSFP port on your network devices until the connector latches. Ensure devices are powered down or follow hot-plug guidelines of the hardware vendor if supported. Verify link status on connected devices and use the DDM/DOM interface, if available, to monitor optical parameters and verify proper operation. The cable is pre-assembled and does not require field termination or cleaning of individual fiber endfaces, but keep connector housings free from dust and debris before insertion.

Recommendations

Use this BlueOptics 1 m QSFP AOC for short-range, high-bandwidth interconnects within racks or adjacent racks. Confirm that your network hardware supports QSFP AOCs and DDM/DOM features for full functionality, and avoid tight bends or mechanical stress on the cable to maintain performance and longevity.
