## Summary description

The BlueOptics X66211A-3-BL is a 3 m InfiniBand fibre optic cable featuring QSFP28 connectors. It provides high-speed data transfer and is designed for reliable performance in data centers and networking applications.

## Long description

The BlueOptics X66211A-3-BL InfiniBand fibre optic cable is a 3 m QSFP28-to-QSFP28 connection designed for high-speed short-reach links in data center and networking environments. It supports 100G-class applications including Ethernet and InfiniBand, and is intended for direct rack-to-rack or within-rack connections where a reliable, low-latency physical link is required.
Advantages
This QSFP28 cable offers passive direct-attach connectivity optimized for short-distance, high-bandwidth links. The cable follows industry MSA guidelines for QSFP28 interfaces and uses high-quality components to provide consistent electrical performance, low insertion loss and low latency. Passive twinax construction keeps power consumption minimal while providing a cost-effective alternative to active optical modules for supported hardware.
Suitable for
Server-to-switch and switch-to-switch connections in racks
High-performance computing clusters using InfiniBand or 100G Ethernet
Short-reach storage and SAN interconnects
Environments where low latency and low power consumption are required
Key specifications
Connector type: QSFP28 to QSFP28
Length: 3 meters
Data rate: up to 100 Gbit/s
Cable type: passive twinax copper (26 AWG)
Supported protocols: Ethernet, InfiniBand, FCoE, Fibre Channel (where supported by hardware)
Compliance: MSA-compliant QSFP28 interface
How to use
Verify that both endpoints support passive QSFP28 direct attach twinax cables and the intended protocol (100G Ethernet, InfiniBand, FCoE, or Fibre Channel). Insert each QSFP28 connector into the corresponding port until it latches; ensure connectors are clean and undamaged before mating. Route the 3 m cable avoiding sharp bends and excessive mechanical stress. The cable requires no external power or configuration; link negotiation and protocol settings are managed by the connected devices.
Usage recommendations
For reliable operation, use this cable for short-distance links inside racks or between adjacent racks where passive QSFP28 twinax is supported. Confirm vendor compatibility with your switch, router or storage platform and consider requesting a test sample if needed. Avoid exceeding the manufacturer-recommended bend radius and inspect connectors periodically for contamination or wear.
