Unlock high-performance 40 Gigabit Ethernet connectivity with the Allied Telesis QSFPER4 QSFP Module. This 40G Small Form-Factor Pluggable (QSFP) transceiver is designed for dense data center and enterprise networks, delivering scalable uplinks with four parallel 10 Gbps lanes. Engineered for reliability and ease of deployment, the QSFPER4 plugs into compatible Allied Telesis devices as a hot-swappable, plug-and-play solution that minimizes downtime while maximizing throughput. Whether you’re building a new data center spine or upgrading campus core links, this module provides the flexible, future-proof connectivity you need to support bandwidth-intensive applications, virtualization, and growing cloud workloads. With a focus on efficiency and compatibility, the QSFPER4 helps administrators consolidate cabling, optimize rack space, and simplify network provisioning across multi-vendor environments.

  • 40 Gbps aggregate performance: The Allied Telesis QSFPER4 uses four parallel 10 Gbps lanes to deliver a total data rate of 40 Gbps, enabling high-bandwidth uplinks between switches, routers, and other core network devices. This architecture supports seamless traffic aggregation for data centers, campuses, and enterprise backbones, ensuring smooth operation for virtualization, storage, and real-time workloads. By providing a wide, scalable path for future growth, the QSFPER4 helps you future-proof your network while preserving existing investments.
  • Hot-swappable, plug-and-play design: The QSFPER4 is engineered for effortless field upgrades and maintenance. Its hot-swappable form factor allows deployment without extensive downtime, letting you swap transceivers during normal operation in many Allied Telesis environments. This feature reduces service interruptions and accelerates capacity expansion in dynamic data center and office network settings.
  • Compact quad-lane QSFP form factor: As a small-form-factor pluggable module, the QSFPER4 achieves high port density without sacrificing performance. The compact size enables data center racks to host more uplinks per switch or chassis, delivering scalable bandwidth while maintaining a tidy, organized cabling layout. This design is ideal for multi-switch fabrics, spine-leaf architectures, and high-density aggregation layers.
  • Reliable, standards-based connectivity: Built to align with industry-standard 40G Ethernet specifications, the QSFPER4 supports four 10 Gbps lanes in a single transceiver, enabling predictable behavior across compatible devices. Its compatibility with Allied Telesis QSFP Series products helps ensure consistent performance, simplifies procurement, and reduces integration risk in multi-vendor environments where 40G links are required for core and distribution layers.
  • Versatile deployment for data centers and enterprise networks: The QSFPER4 is suited for data center interconnects, high-performance campus networks, and backplane uplinks. Its flexible multi-lane approach supports uplink aggregation, link aggregation groups, and rapid scale-out as traffic demands rise. This module is a practical choice for organizations migrating from 10G to 40G, or expanding existing 40G fabrics without overhauling entire switch ecosystems.

How to install Allied Telesis QSFPER4 QSFP Module

  • Prepare the network device by ensuring the port is disabled or that the maintenance window allows hardware changes, following your organization’s change management procedures.
  • Remove any protective dust cap from the QSFPER4 module and the corresponding port on the device, handling the module by its edges to avoid touching optical interfaces.
  • Align the QSFPER4 with the port and gently insert the module until it seats securely in the slot. You may feel a slight click when the module is fully seated and engaged with the electrical contacts.
  • Connect the fiber optic cables to the transceiver as per your network design, ensuring connectors are clean and properly seated in the module’s optical interface. Avoid excessive force to prevent damage to the connectors or ports.
  • Re-enable the port or power up the device and verify link status using the system’s management interface. Confirm the 40 Gbps link is active and monitor LED indicators for healthy operation, throughput, and error-free performance.

So comfy
Solid solid solid shoe. The value for the money you spend is quick to be noticed. Working in a dental office, I’m on my feet a lot and all of these brands who say they were made by nurses blah blah blah are liars. These were finally the shoes that didn’t make my ankles or feet sore. They take shock absorption so smoothly, and allow me to feel supported and comfortable. Wearing them all day isn’t a chore and honestly made me realize I was less grumpy because I was much more comfortable
