## Summary description

The BlueOptics Q9S71A-BO is a 5 m InfiniBand/fibre optic cable featuring QSFP28 connectors. Designed for high-speed data transmission, it ensures reliable connectivity in data centers and networking environments. The aqua color adds a modern touch, while the male/male connector design allows for easy installation and compatibility with various devices.

## Long description

The BlueOptics Q9S71A-BO InfiniBand/fibre optic cable 5 m QSFP28 Aqua is a 5-meter active optical cable (AOC) with QSFP28 to QSFP28 male connectors designed for high-speed 100G data transmission over multimode fiber. Compatible with systems that support 100GBASE-SR4 and QSFP28 MSA standards, this aqua-colored cable integrates transmitter and receiver modules at both ends and is intended for use in data centers, switches, routers and storage systems where a direct, pre-assembled fiber link is required.
Advantages
This BlueOptics AOC conforms to MSA QSFP28 mechanical and electrical specifications and supports 100GBASE-SR4 class applications, enabling simultaneous send and receive optical transmission. The pre-assembled design eliminates the need for patch cords and manual fiber termination, reducing attenuation points and simplifying installation. Components are selected from established communications suppliers to provide consistent performance and long operational life. The cable is immune to electromagnetic interference and provides deterministic, low-latency links suitable for high-throughput environments.
Suitable for
Short-reach 100G connections between QSFP28 ports in switches and routers
High-throughput links in data center top-of-rack and aggregation layers
Server-to-switch and switch-to-switch connections requiring InfiniBand or Ethernet 100GBASE-SR4
Storage system interconnects and high-performance computing clusters
Key specifications
Form factor: QSFP28 to QSFP28 active optical cable
Length: 5 meters
Supported data rate: up to 100 Gbit/s (100GBASE-SR4)
Fiber type: multimode fiber (MMF)
Connector orientation: male/male
Digital Diagnostics Monitoring (DDM/DOM) support for real-time optical parameters where supported by host hardware
Immunity to electromagnetic interference (EMI)
How to use
Plug each QSFP28 connector into compatible QSFP28 ports on the devices to be linked, ensuring proper seating and that the host hardware supports QSFP28 AOC modules and the DDM/DOM interface if diagnostics are required. No additional fiber termination or patching is necessary. After installation, verify link status and negotiated speed on the connected devices and check DDM/DOM values via the host management interface when supported.
Usage recommendations
Use this 5 m BlueOptics QSFP28 AOC for short-reach 100G links inside racks or between adjacent racks to minimize cabling complexity. Confirm device compatibility with 100GBASE-SR4 and QSFP28 AOC modules before deployment and handle connectors with care to avoid contamination; store protective dust caps when connectors are not in use. For monitoring and troubleshooting, enable DDM/DOM on compatible hardware to view real-time optical parameters.
