Worked on Meraki MS355-24X. I see no difference with the original Cisco optics. The price is great for the 40G module.

Based on my experience of purchasing 10G modules from QSFPTEK, their optics work reliably and stably, and these 40G LR4 modules are no exception. We use these transceivers for 40G direct connections in our lab, and they work perfectly with my equipment, transmitting data at 40G rates without any problems.

The switch detects the SFP correctly and the laser is identified as 1310nm. It works well and has no issues this far.

My purchase from QSFPTEK was outstanding! I ordered four 40G LR4 modules for our datacenter, and they performed flawlessly with our Cisco switches, passing all tests. The quality and reliability exceeded my expectations. I will definitely return to QSFPTEK for future needs and highly recommend them.

For almost a month now, I have had these modules installed in our data center. The results have been nothing short of impressive, as they seamlessly connected our Cisco switches, establishing a rock-solid 40Gbe network. I couldn't be happier with my purchase, and the performance of these modules has exceeded my expectations. Without a doubt, I will confidently recommend them to others seeking reliable networking solutions.

This QSFP item is excellent and reasonably priced. It functions properly on my Cisco Catalyst C6824-X-LE series switch and has been thoroughly tested for stability. I will certainly purchase it again for my next project build.
