The Allied Telesis QSFPSR4LC QSFP Module delivers high-performance, 40 Gigabit Ethernet connectivity in a compact, hot-swappable transceiver. Engineered for reliability and easy integration, this QSFP+ module is designed to slot seamlessly into Allied Telesis switches and routers, enabling data centers, campuses, and enterprise networks to scale with confidence. Built to meet industry standards, the QSFPSR4LC combines four parallel 10 Gb channels into a single 40G interface, delivering bandwidth-intensive applications with low latency and minimal footprint. Whether you’re building a new 40G fabric or expanding an existing core, this module provides the versatility and efficiency needed for modern, high-density networks.

  • 40Gbps aggregate bandwidth in a compact QSFP+ form factor: The QSFPSR4LC enables four 10Gbps channels to work in parallel, delivering a total of 40Gbps for high-speed data transfers, storage replication, and backbone interconnects. This design supports next-generation data-center fabrics while preserving valuable rack space.
  • Industry-standard SR4 short-reach performance: Built for 40GBASE-SR4 applications, this module is optimized for multi-mode fiber and short-reach links within data centers and enterprise environments. It provides robust performance across typical campus and data-center topologies, reducing latency and improving efficiency on bandwidth-hungry workloads.
  • Hot-swappable, plug-and-play installation: The QSFPSR4LC is engineered for seamless hot-swapping, allowing network administrators to upgrade or replace transceivers without powering down equipment. This capability minimizes downtime and supports maintenance windows, hot-patching, and rapid network reconfiguration.
  • Broad compatibility within the Allied Telesis QSFP ecosystem: Designed to integrate with Allied Telesis switches, routers, and aggregation devices that support QSFP+ modules, the QSFPSR4LC ensures reliable interoperability across your network fabric. It’s a practical, scalable choice for organizations standardizing on Allied Telesis hardware.
  • Optimized for multimode fiber with reliable reach: The SR4 specification pairs with multimode fiber to achieve efficient, high-bandwidth connections over short distances. This makes it ideal for data-center racks, server-to-switch uplinks, and inter-rack links where patch panels and fiber management play a critical role.

How to install Allied Telesis QSFPSR4LC QSFP Module

  • Power down or prepare for maintenance according to your organization’s change-management policy, then locate a vacant QSFP+ port or identify the existing transceiver to replace.
  • Open the equipment chassis or switch slot cover as required, ensuring you observe static-safe handling procedures to protect the module and host device.
  • Carefully align the QSFPSR4LC with the QSFP+ slot and insert until the module seats firmly. The latch should engage with a click, indicating a secure connection.
  • Attach the appropriate multimode fiber cables to the transmit/receive ports per your network design. Ensure clean, proper terminations and verify that the fiber connectors are correctly mated to minimize insertion loss.
  • Power on the device and monitor the management interface or status LEDs to confirm that the link is established at 40G and that all four lanes are syncing correctly.
  • Run a basic connectivity test (ping, traceroute, or a short data-transfer test) to confirm performance. If necessary, verify the VLANs, routing, and switch fabric configuration to ensure optimal utilization of the 40G link.

Frequently asked questions

  • Q: What is the Allied Telesis QSFPSR4LC QSFP Module? A: It is a 40 Gigabit QSFP+ transceiver designed for SR4 short-reach applications, providing four parallel 10G channels in a single module for high-density data-center and enterprise networking.
  • Q: Is the QSFPSR4LC hot-swappable? A: Yes. It is designed for hot-swapping, allowing non-disruptive upgrades and maintenance in compatible Allied Telesis devices.
  • Q: Which devices are compatible with this module? A: The module is intended for Allied Telesis QSFP-series devices and other 40G-capable platforms that support QSFP+ SR4 transceivers. Check your device’s hardware compatibility list to confirm.
  • Q: What kind of fiber should I use? A: SR4 is typically used with multimode fiber (MMF), such as 50/125 μm optical fiber, optimized for short-reach links within data centers and campuses. Ensure fiber grade (OM3/OM4) matches your reach requirements.
  • Q: What is the maximum link distance? A: For SR4 MMF configurations, typical reach is up to about 100 meters, depending on fiber quality and channel conditions. Longer distances require different transceiver types (e.g., LR/ER) or single-mode fiber designs.
  • Q: How can I verify that the link is up? A: Use the device’s management interface or LED indicators to confirm a solid 40G link. You can also run a quick test using network utilities to verify throughput and error rates across all four lanes.

Cute but at what cost.
Size: 7.5, Color: Champagne
This is probably now the cutest pair of heels I own. But they are not comfortable by any means.

Chic and surprisingly comfortable
Size: 7.5, Color: Champagne
These sandals are gorgeous! The style is sleek and elegant, perfect for both casual and dressy outfits. I was worried they might be uncomfortable, but they’re easier to walk in than I expected and don’t hurt my feet after wearing them for hours. The quality feels great and they definitely look more expensive than they are. Highly recommend if you want a stylish heel that you can actually wear.

Very uncomfortable
Size: 7, Color: Brown Patent
Most uncomfortable shoes I own. The middle part is so hard and digs into your toes making it really painful. I wear a lot of heels and never have I had a pair that hurt this bad.
