This 4x10G QSFP+ transceiver is engineered to be functionally identical to Aristas own QSFP 40G PLRL4L, ensuring seamless interoperability with Arista switches and a broad range of PLR4L capable devices. Built for long haul links over single mode

The Arista Compatible QSFP-40G-PLRL4 from ENET Solutions is a high-performance, OEM-compatible optics module designed to deliver reliable 40GBASE-PLR4L connectivity in data centers using Arista networks. This 4x10G QSFP+ transceiver is engineered to be functionally identical to Arista’s own QSFP-40G-PLRL4L, ensuring seamless interoperability with Arista switches and a broad range of PLR4L-capable devices. Built for long-haul links over single-mode fiber, it combines 1310 nm transmission, robust reach, and intelligent diagnostics to help network engineers scale capacity, simplify deployments, and reduce total cost of ownership. Whether you’re refreshing an aging fabric, expanding a high-density spine-leaf topology, or deploying a new multi-site link, this module provides a dependable, plug-and-play solution that aligns with industry standards and vendor expectations. ENET Solutions emphasizes compatibility, supply chain flexibility, and comprehensive support—delivering a product that pairs strong performance with the assurance of a trusted distributor for network peripherals and optics.

  • 4x10G QSFP+ performance with 1310 nm SMF optics: This transceiver consolidates four independent 10G channels into a single QSFP+ package, delivering a total bandwidth of up to 40 Gbps while maintaining excellent reach and optical performance over single-mode fiber (SMF). The 1310 nm wavelength is optimized for low attenuation and high signal integrity across typical data-center links, enabling stable long-haul links up to the specified range in PLR4L configurations.
  • 2 km reach on SMF with MPO/MTP interface: Engineered for short-to-mid reach deployments, the PLRL4L module supports distances up to approximately 2 kilometers on standard SMF when paired with an appropriate MPO/MTP fiber assembly. This makes it well-suited for campus interconnects, data-center interconnects, and aggregation layers where distance and fiber stability are critical considerations.
  • Digital Diagnostics Monitoring (DOM) and onboard visibility: The module includes Digital Diagnostics Monitoring to provide real-time insight into critical operating parameters such as optical transmit and receive power, temperature, and supply voltage. DOM supports proactive health checks, easier fault isolation, and easier capacity planning, helping administrators optimize performance and uptime across the network.
  • OEM-compatible, Arista-ecosystem ready: While built as a cost-effective alternative to Arista-branded PLR4L modules, this QSFP+ transceiver is designed for seamless integration with Arista switches and other PLR4L-compatible platforms. It offers the same electrical and optical characteristics expected by network engineers, ensuring compatibility, reduced latency in procurement, and a straightforward replacement process without requiring firmware or configuration changes.
  • Durable construction, certification-ready for data centers: The module adheres to rigorous industry standards and is tested to meet the demanding reliability requirements of modern data-center operations. Its robust mechanical and optical design supports hot-swapping in supported environments, minimizes downtime during swaps, and aligns with enterprise-grade service expectations. ENET Solutions backs this product with compatibility guarantees and post-purchase support to ease deployment and ongoing operations.

how to install Arista Compatible QSFP-40G-PLRL4

To install this QSFP+ module, power down the target device only if your environment requires a non-hot-swappable insertion, otherwise follow your vendor’s hot-swap procedures. Remove the existing module from the QSFP+ slot with care, ensuring you discharge static electricity and avoid touching optical surfaces. Align the Arista Compatible QSFP-40G-PLRL4 with the slot and firmly seat the module until it clicks into place. After installation, re-seat any retention mechanisms and reassemble the chassis or panel as needed. Power up the device and verify that link LEDs indicate a successful connection for all four 10G channels. Use your management software to confirm the 40G link status and validate data throughput across the fabric. If Digital Diagnostics Monitoring is supported on the host, review DOM readings to ensure TX/RX power, temperature, and voltage are within expected ranges. Finally, confirm end-to-end connectivity by running a baseline throughput and BER test, and document the results for future reference. Maintain proper fiber handling practices: use correct SMF specifications, ensure the MPO/MTP connector alignment, and avoid bending or stressing the fiber cable to preserve signal integrity over the 2 km reach.

Frequently asked questions

  • Q: Is the Arista Compatible QSFP-40G-PLRL4 truly compatible with Arista switches? A: Yes.

Great for the price
The item is great bit I wish it were a bit more sturdy and it folded flat. It folds into a square so it does take up some room when it's not in use.

Cheap, screw holes don't line up, screen is to short, and bars take WD-40 and a mallet
This has been my worst purchase on Amazon ever. DO NOT BUY. My first issue was that bars #4 and #5 would not go together, I ended up buying WD-40 and a mallet and that kind of got them together. Now I went to but the screen on (which is almost see thought) and the screen is to short. I can't attached the bottom bar to the tall bar. The screw hole is in the wrong spot, so the screen is not secure. No amount of pulling on the screen will make it grown .25" longer. Since I can't get the bars secure the walls are not steady and fall over easily. The feet did go together very nice. I can't return them according to Amazons policy. I bought 2 sets. I'm not going to try to build the other set I have. And I can't take apart the first set, since the bars are so tightly together. Also the polls have rust on them.

Very Poor Built Quality
Color: Black, Size: 3-Panel
They use cheap tarp like cloth that you might find on a tent, so it is not suitable as a teleconferencing background without blur applied. The legs are flimsy and lack rubber feet, so it will scratch floors. The tubing is flimsy and very hard to move and adjust. This is only good if you are setting it up somewhere like a gym or a garage.
