If you maintain things properly, then they will last for a long time. Let’s take a car—if you do the routine oil change and maintenance, then the chances of your car breaking down are minimal. The same concept applies to fiber connectors. If not taken care of, then the quality of your fiber connectors can affect your network.

The light must pass freely from one connector to another.
In this vlog, I explain why high quality connectors should have good polish and loss characteristics.
