The patented Universal Connector Port Adapter allows your fiberoptic Power Meter or any piece of equipment that requires a Connector Port Adapter, universal acceptance of 2.5mm ferrules. The Universal 2.5mm adapter will accept ST, FC, SC, DIN and E2000 connectors or most connectors with 2.5mm ferrules. The connectors are held in place by a custom zirconia sleeve which provides constant tension (avg. 1.5 lbs.) along with ensuring clean ferrule entries. An internal positive stop eliminates the possibility of damaging the detector by pushing a connector in too far. The universal design allows connections without the need to key lock, screw or snap. Simply push your connector ferrule into the universal interface to connect and pull to disconnect.
