## Summary description

The BlueOptics XQ+DA0002-BL is a 2 m InfiniBand fibre optic cable featuring QSFP28 connectors for high-speed data transfer. It is designed for reliable performance in data centers and networking applications.

## Long description

The BlueOptics XQ+DA0002-BL InfiniBand fibre optic cable, 2 m with QSFP28 male-to-male connectors, is designed for short-range, high-throughput interconnects in data centers and networking racks. This cable supports 100G-class links and is intended for direct-attach connections between compatible switches, routers, storage systems and host adapters that accept QSFP28 physical interfaces. It combines a compact form factor with industry-standard connector compatibility to provide reliable electrical signal transfer over a 2 meter span.
Advantages
This QSFP28-to-QSFP28 direct-attach cable offers low latency and low power consumption typical of passive twinax solutions, making it suitable for dense rack environments and adjacent-rack links. Manufactured to MSA-compatible quality standards and using high-grade components, the cable is designed for reliable long-term operation and consistent signal integrity across the supported transmission protocols.
Suitable for
 Short-range 100G links between switches and top-of-rack equipment
 Connections between routers, storage arrays and network adapters
 High-performance computing and InfiniBand cluster interconnects
 Data center rack-to-adjacent-rack cabling where 2 m reach is sufficient
Key specifications
 Cable length: 2 meters
 Connector type: QSFP28 male to QSFP28 male
 Supported data rate: up to 100 Gbit/s
 Cable type: direct-attach twinax (passive) suitable for short distances
 Wire gauge: 30 AWG
 Compliance: MSA-compatible mechanical and electrical interface
How to use
Insert each QSFP28 connector into the corresponding port on the two devices to be linked, ensuring the latch engages and the connector is seated fully. Verify that both devices support passive direct-attach twinax QSFP28 cables and configured link settings match the desired protocol (Ethernet, FCoE, Fibre Channel or InfiniBand). For initial setup, power down or follow hot-swap guidance from the hardware vendor if required, then enable the interface in the device management software and confirm link status and negotiated speed.
Usage recommendations
Use this 2 m passive QSFP28 cable for short, rack-level connections where low latency and low power are priorities. Avoid tight bends and excessive pulling; maintain minimum bend radius as specified by the hardware vendor. Confirm compatibility with your hardware platform before deployment and test links after installation.
