Review on Single Mode Gigabit Ethernet Bi Directional by Quinton Dawon

Generally cheap fiber optic media converters made in China. They tend to lose fiber sync at least once a week and performance drops significantly from 930 Gbps to almost 10 Mbps. The only way to solve the problem is to restart one of the blocks. The user manual lists DIP switches for adjusting settings, but there are no DIP switches on the device. The behavior is unique to these devices as other, more advanced devices using the same fiber optic cable and patch cord will work just fine. As the title suggests, you get what you pay for. Update 09/09/2021: The slowdown is getting worse and is now happening multiple times a day.
