BlueOptics Q28-AOC-3M-AT-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male

The BlueOptics Q28-AOC-3M-AT-BO is a 3-metre Active Optical Cable (AOC) with QSFP28 male connectors on both ends, designed for high-speed InfiniBand and fibre-optic links. It supports 100GBASE-SR4 signaling over multimode fiber with integrated transmitter and receiver electronics in each connector according to MSA QSFP28 specifications. This pre-assembled cable eliminates the need for patch cords and provides a low-latency, EMI-immune connection for switches, routers and storage systems that support QSFP28 AOC modules.

Advantages

The BlueOptics QSFP28 AOC offers 100 Gbit/s aggregated throughput on a short-reach multimode link, with digital diagnostics (DDM/DOM) for real-time monitoring of voltage, temperature, laser bias and optical power. Components are selected to meet MSA mechanical and electrical interoperability requirements, and the cable is built to industry standards (CE, RoHS, FCC). The integrated optical transceivers reduce insertion loss and simplify installation compared with discrete transceiver plus patch-cord setups.

Suitable for

• High-performance data center uplinks and server-to-switch connections
• High-performance computing (HPC) clusters and InfiniBand fabrics
• Storage area network (SAN) interconnects and switch-to-switch links
• Short-reach 100G Ethernet and Fibre Channel over Ethernet (FCoE) links

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Data rate: up to 100 Gbit/s (100GBASE-SR4 equivalent)
• Media: multimode fibre with integrated optical transceivers
• Monitoring: Digital Diagnostics Monitoring (DDM/DOM) per MSA SFF-8472
• Standards compliance: QSFP28 MSA mechanical/electrical specifications; CE, RoHS, FCC

How to use

Insert the QSFP28 connector into compatible QSFP28 ports on your networking devices while the devices are powered according to the vendor guidelines. Ensure ports support QSFP28 AOC modules and, if required, enable DDM/DOM monitoring in the host system to read diagnostics. Use the built-in latching mechanism on the QSFP28 housings to secure the cable. For best results, route the cable to avoid sharp bends and mechanical strain; no field termination or cleaning of patchcord ferrules is necessary since the optical interfaces are factory-terminated.

Usage recommendations

Verify device compatibility before installation and confirm that the host hardware supports QSFP28 AOC modules and DDM/DOM if diagnostic monitoring is needed. Avoid tight bends (observe minimum bend radius), avoid excessive pulling force on the cable, and maintain a controlled environment to achieve expected lifetime and performance.
