Extreme Networks QSFP+ 40GBASE-SR BiDi Transceiver — LC Multi-Mode Fiber Module for High-Density 40 GbE Links

The Extreme Networks QSFP+ Module is a high-performance transceiver designed for optical networks and data centers. It delivers 40 Gigabit Ethernet over multi-mode fiber using 40GBase-SR BiDi technology with an LC connector, enabling dense, scalable uplinks and inter-switch connections across modern networks. Built for reliability and ease of deployment, this QSFP+ transceiver integrates seamlessly with Extreme Networks switches and compatible devices, delivering consistent throughput, low latency, and robust performance in demanding environments. Whether you’re upgrading campus edge links, consolidating data-center backbones, or expanding a hyper-converged infrastructure, this module offers the speed and flexibility needed to power demanding applications.

• 40GBASE-SR BiDi performance on multi-mode fiber enables high-bandwidth links across data-center networks. This transceiver is engineered to handle intense traffic between core switches, aggregation points, and server farms, delivering reliable 40 Gbps throughput with minimal packet loss and low latency. Its BiDi design optimizes fiber usage, helping you maximize your existing fiber plant while simplifying deployment and maintenance in busy data-center environments. The module supports standard Ethernet operations and is compatible with a wide range of Extreme Networks devices, providing a cohesive solution for modern data-center architectures.
• BiDi signaling over multi-mode fiber reduces fiber count and patch panel complexity. By transmitting bidirectionally on a single fiber pair, this transceiver simplifies cable management and improves airflow within crowded racking systems. The result is a cleaner, more scalable fiber plant that lowers installation costs and reduces the likelihood of unwanted crosstalk or signal degradation. It’s an ideal upgrade path for facilities with OM3/OM4 MMF cabling looking to adopt 40G networking without a full fiber replacement.
• Compact QSFP+ form factor for high-density deployments. The transceiver fits standard QSFP+ slots on compatible switches and routers, enabling you to deploy multiple 40G links in a single rack row. This design supports efficient power and cooling management while enabling future scalability as your network grows toward 100G, 400G, or beyond. The module is engineered to minimize insertion loss and maintain stable link integrity even in tight spaces or densely populated data-center racks.
• Easy deployment and hot-swappable operation. The module is designed for plug-and-play integration with Extreme Networks’ optical networking ecosystem, enabling rapid upgrades with minimal downtime. Its compatibility with existing fiber infrastructure helps preserve your investment while delivering immediate performance gains. The transceiver is engineered for reliable operation during continuous data-center workloads, and its robust build supports frequent hot-swapping without sacrificing link quality or device stability.
• Reliability, durability, and environmental resilience. Constructed with high-quality optical components, protective features, and adherence to industry standards, the QSFP+ module is built to withstand the rigors of data-center operation. It offers solid thermal stability, protection against electrostatic discharge, and consistency across temperature ranges common in data-center floors. By combining performance with long-term reliability, this module helps you meet service-level agreements and maintain smooth network operation under heavy utilization.

How to install Extreme Networks QSFP+ Module

• Power down the device or disable the specific port to minimize risk of ESD and misconfigurations before installation.
• Locate an empty QSFP+ port and verify compatibility with your Extreme Networks switch or router. Ensure the port is not locked by any chassis or module management policies.
• Align the QSFP+ module with the slot, making sure the orientation matches the keyed housing. Gently insert the module until it seats firmly and any retention mechanism engages with a click.
• Connect the Multi-Mode fiber optic cables to the LC connectors on the module, ensuring correct polarity and that cables are fully seated in the connectors. Confirm that the fiber type (OM3/OM4 MMF) matches the BiDi specifications of the transceiver.
• Power on the device (or re-enable the port) and verify link status through the device’s management interface. Check for a solid 40G link, monitor error counters, and perform a basic throughput test to confirm expected performance.
