Frequently Asked Questions

What is the primary application for the Dell QSFP28-100G-SR4 transceiver? +

The Dell QSFP28-100G-SR4 is a high-speed, short-reach optical transceiver designed for 100GbE data center interconnects. It is optimized for high-density networking environments where rapid, low-latency transmission is required between core switches, routers, and server clusters over multimode fiber infrastructure.

What transmission distance can I expect from the QSFP28-100G-SR4? +

This module utilizes OM4 multimode fiber to achieve a reach of up to 100 meters. When paired with OM3 fiber, the effective distance is typically reduced to 70 meters. It is the ideal solution for intra-rack or inter-rack connectivity within a standard enterprise or campus data center.

Does the QSFP28-100G-SR4 support MPO/MTP connectivity? +

Yes, this transceiver utilizes an MPO-12 interface to facilitate high-bandwidth parallel optics. By leveraging four transmit and four receive channels, each operating at 25Gbps, the module provides the necessary aggregate throughput for robust 100G network performance across your existing fiber cabling plant.

Is the Dell QSFP28-100G-SR4 compatible with non-Dell networking equipment? +

While specifically engineered for Dell networking platforms, QSFP28 modules follow industry-standard form factors. However, for maximum stability and seamless integration with your existing fabric, we always recommend verifying platform compatibility matrices to ensure the firmware and interface settings are fully optimized for your specific switch hardware.

What are the power consumption characteristics of this 100G transceiver? +

The QSFP28-100G-SR4 is designed for power-efficient operations in high-density environments. It maintains low power dissipation, which is critical for maintaining thermal stability within switches populated with multiple high-speed transceivers, helping to keep operational costs manageable while maximizing overall port density per rack unit.

What fiber type is required for the Dell QSFP28-100G-SR4 module? +

This module operates over multi-mode fiber (MMF) using 850nm VCSEL laser technology. To ensure reliable performance at 100Gbps speeds, it is necessary to use high-quality OM3 or OM4 cables terminated with MPO connectors, ensuring clean signal integrity and minimizing insertion loss within the optical path.

How do I manage or monitor the performance of this transceiver? +

Performance monitoring is handled via the host switch's command-line interface or management software. The module supports Digital Optical Monitoring (DOM), providing real-time data on parameters such as optical output power, input power, temperature, and transceiver supply voltage, which is essential for proactive network troubleshooting.

Can the QSFP28-100G-SR4 handle traffic for high-performance computing clusters? +

Absolutely. This transceiver is well-suited for high-performance computing (HPC) and heavy-traffic environments. By providing a stable 100G data stream with low latency, it meets the demands of bandwidth-intensive applications, virtualization workloads, and large-scale storage arrays, ensuring data moves efficiently across your core switching fabric.

How can I obtain a bulk quote for multiple Dell QSFP28-100G-SR4 units? +

If you are planning a large-scale data center upgrade or require a high-volume quantity of optics, please reach out to our sales team directly. We specialize in accommodating enterprise-level procurement needs and can provide competitive pricing and availability details tailored to your specific project scope and ordering requirements.
