SC UPC Pre-embedded Fiber Optic Fast Connector
The SC UPC field assembly connector is a pre-polished, factory-terminated solution. It is specifically designed for rapid on-site installation in FTTH networks and optical wiring applications. Furthermore, this connector eliminates the need for field polishing, epoxy, and electrical power. Consequently, technicians achieve reliable optical connections in both indoor and outdoor environments, such as utility poles and manholes. Utilizing proven V-groove mechanical splice technology, this component ensures stable core alignment. As a result, it minimizes connection defects caused by installer error.

Installation / Deployment
Installation of the SC UPC field assembly connector is straightforward and can be completed in less than 1 minutes by a skilled technician using standard tools:
-
Strip the fiber buffer coating.
-
Cleave the fiber to the precise length using a fiber cleaver.
-
Clean the fiber using wipes.
-
Insert the prepared fiber into the connector body until it seats securely.
-
Secure the fiber using the internal mechanism and screw boot. No epoxy, polishing, or power supply is required. Optical continuity can be verified post-installation using a VFL.

Selection Considerations
-
Verify whether the network infrastructure requires singlemode or multimode fiber.
-
Confirm the outer diameter of the incoming cable (0.9mm, 2.0mm, or 3.0mm) matches the connector variant.
-
Ensure the required end-face polish (UPC or APC) aligns with the system’s return loss requirements.
-
Consider the environmental conditions of the installation site (operating temperature range).
FAQ
What tools are required for installation?
Installation requires only standard fiber preparation tools: a fiber stripping tool, cleaning wipes, and a fiber cleaver. No electrical power is needed.
Is epoxy required for this connector?
No, the connector utilizes a V-groove mechanical splice, eliminating the need for epoxy or adhesives.
Can this connector be reused?
Product specifications do not indicate reusability; it is intended for permanent field termination.
What is the insertion loss?
The typical insertion loss is less than 0.3 dB, with a maximum of 0.5 dB for UPC end-faces.
Is this connector suitable for outdoor use?
Yes, it is suitable for challenging environments such as telephone poles and manholes, as it does not require a specialized working space.
Conclusion
The SC UPC field assembly connector provides a rapid, reliable, and tool-free solution for FTTH network deployment and optical fiber termination in the field. By eliminating the need for polishing and epoxy, it reduces installation time and complexity while ensuring consistent optical performance and compliance with industry standards like Telcordia GR-326-CORE.
