Introducing the Allied Telesis QSFP28 Module, a high-performance 100 Gigabit transceiver designed for modern data centers, enterprise backbones, and high-density campus networks. The QSFP28 Series delivers industry-standard connectivity in a compact, flexible form factor that fits neatly into existing Allied Telesis infrastructure. Built for reliability and rapid deployment, this hot-swappable transceiver plugs into compatible Allied Telesis devices, enabling teams to scale bandwidth without sacrificing uptime or manageability. Whether you are consolidating servers, extending your core network, or building a spine-leaf topology, the Allied Telesis QSFP28 Module provides the bandwidth, efficiency, and interoperability your network demands. By delivering four parallel lanes of throughput in a single, compact module, this transceiver helps you maximize port density, reduce rack space, and simplify cabling—key advantages in modern data centers where space, power, and cost per Gbps matter as much as raw speed. Trust in a solution engineered to deliver consistent performance across a variety of fiber standards, connectors, and deployment scenarios, backed by Allied Telesis’ reputation for robust, enterprise-grade optics and network hardware.

• Deliver 100 Gbps of throughput using four parallel 25 Gbps lanes, enabling ultra-high-bandwidth links for data center interconnects, east–west traffic in large-scale deployments, and high-performance computing workloads. This architecture supports dense topologies and minimizes latency, latency fluctuations, and oversubscription in backbone links.
• Compact QSFP28 form factor for high port density. The small, plug-in module design fits neatly into standard QSFP28 slots on compatible switches and routers, allowing you to maximize rack space while expanding capacity. Ideal for top-of-rack, leaf, spine, or aggregation layers in modern fabric designs.
• Hot-swappable and tool-free installation. The module is designed to be inserted or removed without powering down the host device in compatible environments, enabling dynamic upgrades and maintenance with minimal downtime. This reduces operational disruption and supports rapid network refresh cycles.
• Seamless integration within the Allied Telesis ecosystem. The QSFP28 Module is engineered for reliable operation with Allied Telesis switches, routers, and optical transport solutions, ensuring compatibility, streamlined management, and consistent firmware support across the product family.
• Durable, enterprise-grade performance for long life in data centers. Built to endure the demands of continuous operation, the module delivers stable throughput, robust error handling, and compatibility with standard fiber layouts and cabling practices, helping you meet service-level agreements and maintain predictable network performance.

How to install Allied Telesis QSFP28 Module

Installing the Allied Telesis QSFP28 Module is straightforward and designed to minimize downtime when upgrading or expanding your network. Follow these safe, step-by-step guidelines to ensure a secure, reliable installation and optimal performance from your new transceiver.

• Prepare the work area and equipment. Power down the host device only if required by your maintenance policy, and ensure you follow ESD precautions (ground yourself and avoid touching the connector surfaces). Confirm that the slot is compatible with a QSFP28 module and that the device firmware supports QSFP28 transceivers.
• Inspect the module and port. Remove any protective caps from the QSFP28 module and from the receiving port (if present). Check for visible damage, dust, or foreign objects, and verify that you’re using the correct type of fiber optic cabling for your specific transceiver variant (for example, MPO/MTP or LC cables as specified by your deployment).
• Align and insert the module. Orient the QSFP28 module so that its connector alignment matches the port orientation. Gently push the module into the slot until it seats with a firm click. Do not force the module; if it doesn’t seat with a positive click, remove and reinsert to ensure proper engagement.
• Secure the module and route cables. If your hardware includes latching mechanisms, engage them to lock the module in place. Connect the corresponding fiber optic cable to the transceiver using the appropriate connector standard for your network (as specified in your deployment plan). Ensure cable management supports ease of maintenance and minimizes bending or stress on the fiber.
• Verify link status and performance. Power up the device (if toned down for maintenance) and check the port status via the device’s management interface. Confirm that the transceiver is recognized, that the link is established, and that traffic channels are up to the expected speed (100 Gbps). Run basic connectivity tests to confirm proper operation and monitor for any error indicators.
