BlueOptics XQ+DA0002-BL InfiniBand optický kabel 2 m QSFP28 samec samec

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.

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.
