## Summary description

The BlueOptics Q28-AOC-20M-PS-BO is a 20m InfiniBand/fibre optic cable featuring QSFP28 male connectors. It is designed for high-speed data transmission in data centers and networking applications, ensuring reliable performance and minimal latency.

## Long description

The BlueOptics Q28-AOC-20M-PS-BO is a 20-meter active optical cable (AOC) with QSFP28 male connectors designed for 100G data transmission over multimode fiber. Built to MSA QSFP28 AOC specifications, this cable integrates transmitter and receiver modules at each end and supports protocols such as 100GBASE-SR4, Ethernet and Fibre Channel over Ethernet to deliver high-throughput, low-latency links in data center and enterprise networking environments.
Advantages
This QSFP28 to QSFP28 active optical cable provides a pre-assembled multimode fiber connection that is immune to electromagnetic interference and requires no field termination or patching. The cable supports Digital Diagnostics Monitoring (DDM/DOM) for real-time status of supply voltage, laser bias current, transmit power, receive power and temperature when the host hardware exposes the interface. Manufactured according to MSA standards and using high-quality optical and electronic components, the product is intended for long service life and high availability in continuous-operation networks.
Suitable for
100G data center links between switches, routers and storage systems
High-performance computing and InfiniBand-style interconnects requiring low latency
Short-reach multimode fiber interconnects within racks or between adjacent racks (up to 20 m)
Environments where immunity to EMI and simplified cabling are required
Key specifications
Length: 20 meters
Connector type: QSFP28 male to QSFP28 male
Data rate: up to 100 Gbit/s (100GBASE-SR4 compatible)
Fiber type: multimode fiber (active optical cable with integrated transceivers)
Form factor compliance: QSFP28 AOC per MSA
Diagnostics: DDM/DOM support (subject to host hardware support)
Typical use: short-reach rack-to-rack or within-rack connections
How to use
Install the BlueOptics QSFP28 AOC by inserting each QSFP28 plug into the corresponding QSFP28 port on your network devices until the module latches. Verify link status through the host device management interface and, if available, read DDM/DOM diagnostics for operational parameters. No fiber polishing or connector cleaning is needed for the pre-terminated AOC; handle the cable by the connector housings and route it to avoid tight bends that can exceed the cable's minimum bend radius.
Usage recommendations
Confirm host device compatibility with QSFP28 AOC modules and ensure the equipment firmware supports third-party AOCs and DDM/DOM if these features are required. Maintain proper bend radius, secure cable routing to prevent strain on connectors, and use the cable for short-reach multimode links within the specified 20 m distance.
