We've been operating these modules around the clock in a metropolitan Gigabit Ethernet network for more than six months. Optical power remains stable, no unexpected disconnects have occurred, and the 20 km OS2 fiber links continue to perform exactly as expected. Overall, an excellent OEM-compatible solution for long-distance CWDM deployments.
