BlueOptics JNP-100G-2X50G-5M-BL InfiniBand-kuitu-kaapeli QSFP28 5 m uros/uros

The BlueOptics JNP-100G-2X50G-5M-BL InfiniBand fibre optic cable QSFP28 5m Male/Male is a 5-metre high-speed connection solution with QSFP28 connectors for direct device-to-device links. Designed to support 100G class applications, it provides a compact, single-cable option for short-reach connections in racks and adjacent rack rows. The cable is built to industry mechanical and electrical specifications to ensure compatibility with hardware platforms that accept QSFP28 100G connections and is suitable for InfiniBand, Ethernet and similar high-performance interconnects when used with compatible ports and protocols.

Advantages

This QSFP28 male-to-male cable delivers a low-latency, high-throughput physical connection for short-distance links, reducing the need for additional transceivers. The 5 m length balances reach and manageability in data centre racks. As a passive direct-attach style solution, it offers low power consumption and simplified installation compared with active optical assemblies. Components and construction comply with common MSA guidelines to provide stable signal integrity and long-term mechanical reliability.

Suitable for

• Direct QSFP28-to-QSFP28 connections within and between adjacent server racks
• High-performance computing clusters using InfiniBand or 100G interconnects
• Switch-to-switch or switch-to-storage short-reach links in data centre topologies
• Environments where low latency and low power consumption are required

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 5 metres
• Application: InfiniBand and 100G-class data links (supporting Ethernet, FCoE, Fibre Channel where supported)
• Transmission: designed for short-reach, high-bandwidth low-latency connections
• Construction: passive direct-attach style cable optimized for rack and adjacent-rack connections
• Compliance: manufactured to meet common MSA mechanical and electrical requirements

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked. Ensure both ports support passive direct-attach cabling and the same transmission protocol (e.g., InfiniBand or 100GBase). Route the 5 m cable carefully through the rack to avoid sharp bends and abrasion; maintain the manufacturer's recommended bend radius. After physical connection, verify link status and settings in the devices' management interfaces and confirm negotiated speed and protocols are correct.

Recommendations

Use this cable for short-distance, high-bandwidth links where both endpoints explicitly support QSFP28 passive direct-attach connections. Avoid excessive bending, exposure to liquids, or mechanical strain. For interoperability, confirm device firmware and port specifications accept passive QSFP28 twinax-style connections and that the chosen protocol (InfiniBand, Ethernet 100G, etc.) is supported by both endpoints prior to deployment.
