Fibre optic cable Intel E100GQSFP28SRX 100G QSFP28 5A991

The Intel E100GQSFP28SRX 100G QSFP28 5A991 is a fibre optic cable engineered for 100G data transmission using a QSFP28 interface. Designed for data center and enterprise network environments, this cable supports high bandwidth links with low latency characteristics suitable for InfiniBand and other high-speed fabric interconnects. The construction ensures signal integrity over the supported reach and is compatible with equipment that accepts QSFP28 connectors.

Advantages

This fibre optic cable provides stable 100 gigabit performance with a compact QSFP28 form factor, enabling dense port configurations in switches and adapters. Its design focuses on minimizing insertion loss and maintaining signal quality for high-throughput applications. The cable is suitable for environments where consistent, low-latency data transfer and compatibility with InfiniBand topologies are required.

Suitable for

• 100G uplinks and switch-to-server connections in data centers
• High-performance computing clusters using InfiniBand fabrics
• Enterprise backbone links and aggregation layers
• Low-latency trading platforms and storage networks

Key specifications

• Connector type: QSFP28 on each end for 100G interfaces
• Data rate: 100 gigabits per second support
• Media: multimode or single-mode fibre as applicable to installation (verify media type before deployment)
• Typical use: short- to medium-reach high-bandwidth interconnects (refer to system compatibility for exact reach)
• Physical: compact QSFP28 form factor for high port density deployments

How to use

Install the cable by aligning the QSFP28 connectors with the device ports and engaging the connector latch until secure. Verify link status on connected devices and confirm that port configurations match 100G operation. When using in InfiniBand fabrics or other high-speed networks, ensure transceiver and switch firmware are compatible with 100G QSFP28 modules. Route the cable to avoid tight bends and protect connectors from contamination during handling.

Usage recommendations

Inspect connector endfaces before installation and use appropriate cleaning tools if contamination is present. Maintain bend radius guidelines and avoid excessive tensile strain. Confirm compatibility with switch and adapter vendor specifications to ensure reliable 100G operation in InfiniBand and Ethernet environments.
