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.

Beware - Few Instructions Fiddly Software!
Color: dark
Against my better judgement I'm going to go ahead and keep this little device since I was able to figure out how to move around in the software. So these are first impressions, but clearly, I'm not impressed so far. If you're not comfortable with pressing buttons to see what happens then I'd advise you to look elsewhere. The device is packaged nicely, and when plugged into power, it popped right on and started recording. I know the product description says it comes with a 64 gb TF (mico-SD) card but the device's specs say it's only capable of seeing 32 gb. To get the card in and out of the device (because the only way to save videos is to remove it from the camera, put it into a card reader and plug that into your PC, laptop, or smartphone) both the power cable and the rear facing camera cables have to be unplugged. The instructions say it comes with a suction cup mount...it does not. You have to fiddle with a sticky pad to attach to your windshield, pull the cover off the other side and attach the camera to the sticky pad. Make sure the camera is placed where you want it because you only get one shot apparently. We'll see how it does, the picture appears clear on its little screen and it plays videos back quickly, it's just extremely fiddly moving around with the buttons and there are NO instructions how to get to those functions. But, it is what it is, and you get what you pay for...the jury's still out on it's functionality.

Better Than Manscape
Color: Gold &black
This little trimmer is incredible. I have had a Manscape for a few years now, but it nipped me and the battery life was garbage. However, this bad boy hasn't cut me once, it charges quick, and lasts forever. My wife and I will both use it back to back and has no issues. She uses it in the shower and it holds up. It's comfortable, doesn't over heat, and works great. Again... I think it's way better than manscape.

Highly recommended
Color: Bright Purple
I recently purchased the OLOV Electric Body Hair Trimmer and I give it a full 5 stars! This isn’t my first time buying from OLOV—my initial purchase was for myself, and I’ve been impressed with its quality and performance. This time, I bought one for my wife, and she absolutely loves it! It’s easy to use, reliable, and delivers excellent results. Highly recommend this trimmer for anyone looking for a dependable grooming tool.

Nice shaver and is easy to use.
Color: Gold &black
The olov electric body hair trimmer does a good job shaving the arms and legs but you have to be careful when shaving the private area . You have to stretch the skin on the privates as you shave between the inner thigh it will nick the skin on the scrotum.The olove is narrow enough to shave the privates.
