BlueOptics MA-CBL-100G-3M InfiniBand fibre optic cable 3m QSFP28 Male/Male

The BlueOptics MA-CBL-100G-3M InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3-meter multimode optical link designed for high-speed server and switch interconnects. With QSFP28 connectors on both ends, this cable supports data center topologies that require 100G-class InfiniBand or Ethernet connectivity over short to medium distances. The construction emphasizes consistent signal integrity and low insertion loss to maintain throughput in dense rack and chassis installations.

Advantages

This fibre optic cable provides a standardized QSFP28-to-QSFP28 connection for 100G-class links, enabling straightforward integration with compatible transceivers and ports. Its 3 m length balances reach and manageability in rack layouts, helping to reduce cable clutter while preserving signal performance. The multimode optical design and quality connector polishing reduce reflections and insertion loss, contributing to stable high-bandwidth transmission in demanding networking and compute environments.

Suitable for

• Short-reach data center uplinks between switches and servers
• High-performance computing clusters using InfiniBand interconnects
• Top-of-rack and middle-of-row cabling where 3 m reach is sufficient
• Environments requiring QSFP28-compatible 100G links for storage and virtualization

Key specifications

• Cable type: multimode fibre optic
• Connector type: QSFP28 Male to QSFP28 Male
• Length: 3 metres
• Supported data rate: up to 100 Gbps class links (InfiniBand / Ethernet compatible)
• Optical performance: low insertion loss and optimized for short-reach multimode applications
• Typical use case: data center and server interconnects

How to use

Before installation, verify that both ports support QSFP28 connections and the intended protocol (InfiniBand or Ethernet) at the required data rate. Align the QSFP28 connectors with the port guides and insert them firmly until the connector latch engages. Route the cable to avoid sharp bends and mechanical strain; maintain the specified minimum bend radius for multimode fibre. When removing the cable, release the latch and pull straight to avoid damaging the connector. Periodically inspect connectors for dust and contamination and clean with appropriate fibre optic cleaning tools if needed.

Recommendations

To ensure consistent 100G performance, use this cable within data center structured cabling layouts and pair it with compatible QSFP28 ports and transceivers. Store and handle the fibre carefully to prevent microbends, and perform connector cleaning and periodic link testing as part of routine maintenance.
