BlueOptics QSFP28-100G-CU3M InfiniBand optický kábel 3 m konektor samec/konektor samec

The BlueOptics QSFP28-100G-CU3M InfiniBand fibre optic cable 3 m Male/Male is a 3-metre high-speed pass-through cable with QSFP28 connectors designed for 100G network links. It provides a direct electrical connection between QSFP28 ports for short-reach, high-bandwidth applications in data centres and professional networking environments. The cable is intended to support InfiniBand and 100 Gigabit Ethernet interfaces where QSFP28 form-factor modules are used.

Advantages

This QSFP28 copper/active pass-through cable offers a compact, single-cable solution for linking QSFP28 ports without external transceivers. Its 3 m length balances signal integrity and installation flexibility for short interconnects within racks and between adjacent racks. The Male/Male connector configuration simplifies direct port-to-port connections, maintaining the native 100G interface and reducing the need for additional optics or modules.

Suitable for

• Short-reach 100G links inside data centre racks
• Interconnects between networking switches and servers with QSFP28 ports
• High-bandwidth InfiniBand connections in HPC clusters
• Temporary or permanent connections where transceiver-free cabling is preferred

Key specifications

• Cable length: 3 metres
• Connector type: QSFP28 Male to QSFP28 Male
• Supported interface: QSFP28 100G / InfiniBand
• Intended use: short-reach, high-speed direct connection
• Physical format: 4-channel high-density QSFP28 pass-through cable

How to use

Install the cable by aligning each QSFP28 plug with the corresponding port on your switch, server or transceiver cage and insert until the connector latches. Ensure both ends are fully seated to establish a stable 100G connection. Route the cable to avoid tight bends and mechanical strain; maintain recommended bend radius for high-density QSFP28 assemblies. When disconnecting, release the latch mechanism before pulling to prevent connector or port damage.

Recommendations

Verify port compatibility and firmware requirements on networking equipment before deployment. Use this cable for links within the same rack or between adjacent racks to ensure optimal signal integrity. Keep connectors clean and protected when not in use and avoid excessive bending or crushing of the cable to maintain long-term performance.
