Terminate your bulk fiber optic cabling with the ECOConnector Single Mode Zip-Cord ST Fiber Optic Connector from TechLogix Networx to help ensure a fast and reliable connection. Designed specifically to fit onto 250µm, 900µm, and 2mm zip-cord style single mode (OS1, OS2) cables, this 50-pack of blue ST connectors feature a standard UPC polish and helps to ensure perfect alignment with reduced refraction and signal loss. Install the connector in about two minutes without the need for special tools, epoxy, polishing, or crimping. A large built-in verification window, self-centering alignment groove, and button for one-click termination and locking jig release makes the process relatively quick and easy. You can also re-use this connector with five or fewer termination cycles recommended.
