Option 1: FC, SC, ST Interchangeable / 2.5mm universal connector adapter Port is the most commonly used connector type for Joinwit Optical power meters. It features:

　　a) Interchangeable FC, SC, ST connector adapters, which means the user can choose any of the FC, SC, ST adapters to be fixed well with the connectors. Changing the adapter is very simple: unscrew one and screw in the next. Please refer to the picture below for a better understanding.

　　b)  2.5mm Universal connector adapter. After unscrewing any of the interchangeable connector adapters, the user will see a fixed 2.5mm metal plug which we call a 2.5mm universal connector adapter. It can accept most of the 2.5mm diameter ferrule connectors, such as FC,SC, ST,DIN, E2000 and SMA. It means that with one plug a variety of connectors can be connected as long as the ferrule diameter is 2.5mm. These connectors however use only a push/pull mechanism and cannot to be fixed or screwed. Please refer to the right picture for a better understanding.

　　Note: Usually, if no customer special requests, we will use this type connector port as the standard adaptor for our Handheld optical power meters.
