Extreme Networks QSFP28 Module — 100GBase-FR, LC Duplex, Single-Mode

Designed for high-density optical networks, the Extreme Networks QSFP28 Module delivers reliable 100 Gigabit Ethernet connectivity over single-mode fiber using the 100GBase-FR standard. This hot-pluggable transceiver is built for data centers, enterprise backbones, and service-provider networks that demand scalable uplinks with long reach and trusted performance. With the QSFP28 form factor, it fits into modern switches and routers with minimal footprint while maximizing port density and energy efficiency. Whether you are refreshing an aging fabric or building a new 100G spine-leaf topology, this module provides a robust, low-latency uplink solution that aligns with Extreme Networks' stringent standards for interoperability, reliability, and ease of management. It is designed to reduce total cost of ownership by leveraging existing fiber infrastructure and enabling higher bandwidth without a complete hardware refresh.

In the 100GBase-FR specification, data is transmitted over single-mode fiber at 1310 nanometers, allowing full 100 Gbps throughput across links up to 2 kilometers. The LC duplex optical interface is designed for clean, reliable fiber terminations, and the transceiver is engineered to maintain strong performance over a wide range of environmental conditions, including temperature and mechanical stress typical in data centers. The module's design emphasizes tight optical tolerances, excellent return loss performance, and robust ESD protection, helping maintain signal integrity across the fabric. The result is a future-proof upgrade path that preserves investment in fiber infrastructure while delivering the bandwidth required by modern applications—cloud services, virtualization, AI workloads, real-time analytics, and latency-sensitive workloads at the edge.

Extreme Networks emphasizes quality and compatibility. The QSFP28 module is built to integrate seamlessly with Extreme Networks' switches, routers, and optical transport solutions, providing predictable behavior, straightforward device management, and simplified troubleshooting. The transceiver is designed to deliver consistent performance in dense data center environments, offering low insertion loss, robust mechanical design, and alignment with industry standards for cross-vendor interoperability where supported. IT teams can rely on a clear path to deployment for 100GBASE-FR uplinks, enabling efficient data center interconnect (DCI), campus backbones, and high-capacity WAN aggregation with minimized risk of misconfiguration or compatibility issues. With Extreme's management tools, administrators can monitor link quality, error rates, and temperature to ensure healthy operation and to plan maintenance windows with confidence.
