Great for extending our Homelab NAS over SMF. The commercial 0-70°C operating temperature is stable in our indoor rack. Very low power draw at 3.3V, highly recommend for B2B purchases.

Needed reliable 1.25Gbps optical modules for our multi-brand environment. Plugged these into Ubiquiti, Brocade, and H3C gear without any MSA protocol warnings. Outstanding Tx/Rx sensitivity and minimal optical dispersion.
