    We used the 10G LRM over OS2 single-mode fiber for a mid-range link and it's been running smoothly. Setup was simple and the connection has stayed stable since day one. A good fit when you need around 2 km reach without stepping up to longer-reach optics.

    We deployed a few 10G LRM2 modules in an older data center where multimode fiber runs couldn't easily be replaced. These worked better than expected, with no errors, and the extended MMF reach really saved us time and cost. Only downside is they're slightly more expensive than standard 10G modules, but the convenience makes it worth it.

    Very satisfied with the 10G LRM2 transceivers, stable 2km links and easy installation. The price is reasonable, delivery was fast, and compatibility with our Cisco switches is perfect. Will purchase again for future projects!

    We use the 10G LRM2 module for building-to-building connections around 2 km. The signal is consistent, the latency is low, and installation was easy, plug and play. It’s a practical solution for medium-distance applications in enterprise networks.

    We needed a cost-effective solution for a 2 km link in our lab and tried the 10G LRM2 module. Delivery was fast, packaging was neat, and installation took only minutes. The module runs smoothly with low latency and reliable transmission, exactly what we needed. What impressed me most was the price—far more affordable than branded options but with no compromise in quality or compatibility. Definitely worth recommending.

    This 10G LRM2 module turned out to be exactly what I needed for my setup. The price was fair, and the shipping speed was faster than I expected. Installation was smooth, and the module was recognized immediately by my equipment without compatibility issues. The build quality feels solid, and so far, performance has been very stable. Overall, a great purchase experience and excellent value for money.

    I need to connect to a device within 1.5 km, but the 10G LR module is too long for SR. My account manager recommended the 10G LRM2, which supports transmission within 2 km and is more affordable than LR. I'm very grateful to QSFPTEK.
