NVIDIA/Mellanox Compatible 800GBASE-LR8 (2xLR4) Twin-port OSFP IHS/Closed Finned Top PAM4 1310nm 10km Dual MPO-12/APC DDM SMF InfiniBand NDR Optical Transceiver Module for Quantum-2 InfiniBand and Spectrum-4 Ethernet Air-Cooled Switches

These LR8 units easily handle our 10km link. Alisha helped me pick the right ones, and they haven't skipped a beat.

This LR8 module was used for a longer-distance 800G link. Compared with shorter-reach optics we tested before. The optical performance has been consistent, and it has been running reliably since installation.

Selected this LR8 module for a project that required longer fiber runs between network segments. The LC interface made installation convenient since it matched our existing cabling infrastructure. Being able to achieve 800G connectivity without redesigning the fiber plant was a major advantage for this deployment.

We needed optics for a longer-reach project, and these performed exactly as advertised. No signal issues and plenty of margin on the links.

Needed a long-reach 800G solution between two buildings on campus and decided to try this LR8 module. Optical power levels were healthy, and performance has been rock solid since deployment. I'm very satisfied with the result.

After running these for several months, we've had zero failures. Consistent performance like this keeps us coming back for future projects.

Many products perform well when first installed, but the real differences become apparent after a few months. This LR8 has been running continuously for some time, surviving peak business periods and maintenance windows, and its current condition is similar to when it was first launched. There have been no significant fluctuations in optical power or degradation in link quality. From a long-term usage perspective, this is something I'm quite satisfied with.

Our primary requirement for optical modules is reliability. Since LR8 went live, it has been running very stably; services haven't experienced issues due to link problems, and the monitoring system rarely records any anomalies. This is quite good for a critical connection.

Big shoutout to Talia, who was super responsive and walked me through the LR8 specs step by step. I had a ton of questions about 10km reach and compatibility with our existing fiber plant, and she answered every single one without making me feel dumb. Ordering was a breeze, modules arrived well-packaged, and they've been running rock-solid between our two buildings ever since. This is my second order from QSFPTEK and definitely not my last. Keep up the good work, team.

The build quality feels solid, and for the price, it's a fantastic value. I'd recommend it, but just order with a little buffer time for delivery. I'll probably order again, just next time I'll plan ahead better.
