## Summary description

The BlueOptics X66211B-5-BL is a 5-meter InfiniBand fibre optic cable featuring QSFP28 connectors. Designed for high-speed data transfer, it ensures reliable connectivity in data centers and high-performance computing environments. The male connectors provide easy installation and compatibility with various devices.

## Long description

The BlueOptics X66211B-5-BL InfiniBand fibre optic cable 5 m QSFP28 is a 5‑metre high‑speed interconnect with QSFP28 male connectors designed for short‑range, high‑bandwidth links in data centres and high‑performance computing environments. It provides a compact physical connection for 100G-class InfiniBand and Ethernet applications, offering a standardized QSFP28 interface suitable for compatible switches, routers and storage hardware, and is intended for direct rack or adjacent‑rack connections where reliable, low‑latency data transfer is required.
Advantages
This 5 m QSFP28 cable supports high data throughput and low latency typical for InfiniBand and 100G Ethernet signalling. The cable is built to MSA‑aligned mechanical and electrical dimensions for QSFP28 interconnects, ensuring consistent fit and interoperability with equipment that supports QSFP28 modules. Its fixed length and passive design simplify installation and reduce the number of active components in short‑reach links, contributing to lower power consumption and minimal maintenance over the product lifecycle.
Suitable for
Short‑reach links inside racks and between adjacent racks in data centres
High‑performance computing (HPC) clusters and InfiniBand fabrics
100G Ethernet, FCoE and storage interconnects where QSFP28 is supported
Switch‑to‑switch, switch‑to‑server and server‑to‑storage connections requiring 5 m length
Key specifications
Connector type: QSFP28 male to QSFP28 male
Cable length: 5 metres
Supported protocols: InfiniBand and 100G‑class Ethernet
Form factor: Passive direct attach/fixed interconnect for short distances
Typical applications: High‑bandwidth, low‑latency rack interconnects
How to use
Install the BlueOptics X66211B-5-BL by aligning each QSFP28 male connector with the corresponding QSFP28 port on the devices to be linked and insert until the connector latches. Confirm both endpoints recognise the link and configure port settings on the connected devices according to the chosen protocol (InfiniBand or Ethernet). For passive direct attach use, ensure the host hardware supports passive QSFP28 DAC or passive QSFP28 interconnects; consult device documentation for compatibility and any required port configuration or firmware considerations.
Usage recommendations
Use the cable within standard data centre temperature and humidity ranges, avoid sharp bends and maintain recommended minimum bend radius. Route the cable to minimise mechanical stress and keep it away from heat sources and moving parts. Verify compatibility with device vendor specifications before deployment and, when possible, test the link in your environment to confirm expected throughput and latency characteristics.
