Good performance, but the shipping took a bit longer than I'd like to get to the Midwest. Otherwise, the transceiver is solid and hasn't had any errors since I installed it.

I've been deploying these in outdoor, temperature-regulated cabinets for about two months now. Even with the humidity and fluctuating loads, these SFP modules have not skipped a beat. The DDM implementation is quite responsive, which is a lifesaver for identifying potential fiber degradation before it causes a full outage. They are a reliable, cost-effective alternative to expensive brand-name optics.

Used these for a small home lab NAS upgrade. The 10km range is more than enough, and the DOM monitoring makes tracking signal strength super easy. Definitely better than buying overpriced OEM modules.

We swapped out some old transceivers in our server room for these. No downtime during the migration, and the 1310nm wavelength is stable. Will be buying more for the next phase.

The product itself works great and performs as expected in our lab tests. Only taking one star off because the packaging was a bit flimsy and one of the protective caps was missing. Otherwise, no complaints!

Works fine on our Juniper gear. The module got a bit warm during heavy traffic, but it stayed within operating specs. Good value, but maybe keep an eye on your airflow in the rack.
