Are standard fast cure LC connectors interchangeable with Secure LC connectors? Or do I have to use the connectors that come in the kit for the Secure LC field install kit? Cause they look very similar.
The two connectors are different. The connector used with the Secure LC system is very similar to the standard FastCure connector but it has a different shaped frame to accomodate the Secure LC housing. So no you would not be able to use a standard LC FastCure connector with a Secure LC kit.
