Step into the next level of data-center performance with the Lenovo 40GBase QSFP+ Bi-Directional Transceiver. Engineered for reliability and scalability, this high-density module empowers modern networks to handle demanding workloads—from cloud services and virtualization to big data analytics and AI-driven applications. Built around the 40GBASE-SR specification, it delivers a robust 40 Gbps data rate over multi-mode fiber, enabling fast, efficient interconnects between core switches, aggregation layers, and top-of-rack devices. The bi-directional design helps optimize fiber usage by enabling bidirectional communication on shared fiber paths, reducing cable complexity and improving cable management in dense deployments. Whether you’re refreshing an aging data-center fabric or expanding a new spine-leaf architecture, this transceiver is designed to deliver dependable performance in Lenovo environments and with other standards-compliant switches and routers.

  • High-speed 40 Gbps performance: The transceiver provides a four-lane 10 Gbps aggregation, delivering a total of 40 Gbps of throughput for ultra-fast intra-data-center links and backplane-to-core connections, ensuring low latency and consistent bandwidth for virtualization clusters and storage networks.
  • Bi-directional efficiency: Bi-directional operation on a single fiber pathway reduces fiber count and simplifies cabling in dense deployments, offering greater port density without sacrificing performance or reliability.
  • Multi-mode fiber compatibility: Optimized for common multi-mode fiber types (MMF), enabling cost-effective deployments with OM3/OM4 cabling that are widely available in enterprise data centers and campus networks.
  • Easy Lenovo integration: Designed for plug-and-play compatibility with Lenovo networking gear and other standards-based switches, supporting seamless hot-swapping and quick field replacements to minimize downtime.
  • Durable, reliable design: Built to withstand data-center temperature variation, vibration, and long-term operation with proven interoperability across vendor ecosystems, ensuring stable performance in mission-critical workloads.

Technical Details of Lenovo 40GBase QSFP+ Bi-Directional Transceiver

  • Compatibility: Interoperable with other 40GBASE-SR QSFP+ devices and Lenovo networking platforms, subject to standard vendor interoperability guidelines.
  • Power Requirement: Low-power module designed to minimize thermal impact in dense racks and blade ecosystems.

How to install Lenovo 40GBase QSFP+ Bi-Directional Transceiver

  • Power down the affected device if recommended by your data-center procedures, or verify hot-swap support before installation.
  • Locate an available 40G QSFP+ slot on your switch, router, or blade chassis and remove any existing module following the device’s service manual.
  • Align the Lenovo QSFP+ transceiver with the slot and insert firmly until it seats and the locking mechanism engages, ensuring a secure connection.
  • Connect the fiber cables to the LC connectors on the transceiver, using MMF that complies with OM3/OM4 specifications and ensuring the polarity is correct for bidirectional links if using a shared fiber path.
  • Power on the device and verify link status via the management interface, LEDs, or monitoring software. Confirm that the interface negotiates at 40 Gbps and that there are no reported errors.

Frequently asked questions

  • Q: What is the Lenovo 40GBase QSFP+ Bi-Directional Transceiver suitable for?

    A: It is designed for short-reach 40 Gigabit Ethernet connections within data centers and enterprise networks, enabling high-bandwidth interconnects between core switches, leaf switches, and high-performance servers using multi-mode fiber.

  • Q: What type of fiber and connectors does this transceiver use?

    A: The module is configured for multi-mode fiber and uses an LC connector on the fiber side, aligning with common MMF deployments. Ensure your cabling matches the fiber type (OM3/OM4) to achieve the stated reach.

  • Q: How far can I run a link with this transceiver?

    A: Reach varies with fiber grade: typically up to 100 meters on OM3 and up to 150 meters on OM4; actual distance depends on cabling quality, connector integrity, and ambient conditions.

  • Q: Is this transceiver compatible with non-Lenovo switches?

    A: Yes. As a standard 40GBASE-SR QSFP+ module, it is designed to be interoperable with other vendor equipment that adheres to the 40GBASE-SR specification, provided proper cabling and port configurations are used.

  • Q: Can I hot-swap this transceiver?

    A: In many data-center environments, QSFP+ transceivers are hot-swappable. Always follow your equipment’s hot-swap procedures and power-down policies if required by your organization’s guidelines.

Fluffed to perfection.
Model: Soft-2PK, Size: Queen
I was a tad disappointed when I first opened the vacuum sealed packaging. They were flat and thin and disappointing. Once I fluffed them (took about 15 minutes per pillow) they were suddenly AMAZING. Fluffy and soft and perfectly supportive.

Ok
Model: Soft-2PK, Size: Queen
These pillows are ok. I would not purchase them again as they go flat, but they will fluff up again once you fluff them.

Firm/No Pillowcase To Fit/Gives Full Neck & Head Support
Color: White, Size: Standard
While the material cover is soft and the filling in the pillow itself is soft, there is too much filling stuffed inside. But to be fair I have a serious neck problem. I feel that if we were given the option to remove some of the filling to meet our comfort level then this would be the perfect pillow. I have been trying to find a pillow with that option. I will be cutting the pillow to remove the filling and place it in another pillow that has a zipper on the side to add inside. Over the yrs that pillow stuffing has become lumpy and needed replacing and can’t find another like it or the right filling. Luckily this pillow has the right stuffing so I am happy with my purchase. My husband has the second pillow and does agree with me that it is a bit on the firm side but he likes the firmness of it and it does support his head & neck well and it is comfortable. Only big issue for us is that there are no pillowcases to fit. When trying to fit a pillowcase on it - it makes the pillow way too tight & firm and uncomfortable. They need to make a pillowcase for this pillow. A standard, Queen, king does not fit. UPDATE: 1/13/2025 This order came with 2 pillows. My husband has the 2nd pillow and so far he has no complaints with the pillow. For me to be fair I have serious issues with my neck. I have a lot of hardware in my neck including several small rods in my neck so to find a good pillow to be comfortable is very difficult to find. My only solution is to have a pillow with a zipper which I can remove or add the filling as needed, it just has to be the right kind of filling. This pillow has the right kind of filling to where I can put inside my original pillow that I have. Over time the filling just becomes lumpy and uncomfortable to which I need to refill with new filling. After a long search I found this pillow which had the same kind of filling I’ve been looking for to restuff my pillow. So with that said I can’t really review this product myself except to say that it has the right filling inside to help me with my sleeping but I can say with what my husband tells me which is he has no complaints, in fact he is happy with it and it supports his head & neck well. If you have a serious neck problem this might not be the pillow for you unless you already have a pillow with a zipper and can restuff it with any kind of filling then I do recommend the filling in this pillow. Sorry for the long review but I do hope it helps anyone who is struggling and is in the same situation as me.

Quality maintained
Color: White, Size: Queen
A client I service has these. She said she got them YEARS ago at Macy’s. Each time I change her linens I admire them for their plumpness. I found the well worn name tag then ordered hoping the quality hadn’t fallen since “years ago.” As pillows differ for everyone, I have found MY comfort level with this pillow.
