InfiniBand-kuituoptinen kaapeli BlueOptics QSFP-100G-D-CAB-2M-BL 2 m uros/uros

The BlueOptics QSFP-100G-D-CAB-2M-BL is a 2‑metre direct-attach cable with QSFP28 connectors on both ends designed for high-speed InfiniBand and short‑reach fibre optic or electrical connections. It supports 100Gb/s links between compatible QSFP28 ports and is suited for rack-to-rack and in-rack connections in data centres and high-performance computing environments where low latency and reliable connectivity are required.

Advantages

This 2m QSFP28 cable provides a straightforward, low-power connection option for short-distance 100G links with minimal signal loss. The cable is compliant with industry MSA connector profiles for QSFP28 interfaces and is compatible with hardware platforms that support QSFP-100G direct-attach solutions. Designed for consistent performance, the cable is intended to deliver stable throughput for Ethernet, Fibre Channel, FCoE and InfiniBand applications up to 100G when used within its supported distance.

Suitable for

• High-performance computing clusters requiring 100G links
• Data centre rack-to-rack and in-rack connections
• Switch-to-switch or switch-to-server short-reach links
• Storage systems and SAN connections supporting 100G

Key specifications

• Connector type: QSFP28 to QSFP28 (male/male)
• Nominal length: 2 metres
• Supported link rate: up to 100 Gbit/s
• Cable type: direct-attach (twinax / short-reach electrical/direct attach copper or equivalent form used for QSFP28 DAC)
• Designed for use in short-distance data centre environments with low latency requirements

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on your compatible devices, ensuring both ports support direct-attach QSFP28 connections. Handle the cable by the connector housings when plugging or unplugging; avoid sharp bends and excessive twisting along the cable to maintain signal integrity. Confirm link negotiation and interface status on connected devices and verify that the platform firmware or software accepts passive or active direct-attach cables as required by your equipment.

Recommendations

Use this 2m QSFP28 direct-attach cable for short, point-to-point 100G links inside racks or between adjacent racks. Check hardware compatibility lists and firmware requirements of your switches, routers or storage systems before deployment. Avoid routing the cable near strong electromagnetic interference sources and maintain bend radii consistent with QSFP28 connector guidelines to ensure reliable long‑term operation.
