Fiber Patch Cord SC/UPC-SC/APC Simplex Single Mode 1M 2.0

SC UPC and SC APC are two types of singlemode fiber connectors distinguished by their endface polish, affecting return loss and reflection, with APC offering superior performance for reflection-sensitive applications.

SC (Subscriber Connector or Standard Connector) is a widely used fiber optic connector with a 2.5 mm ferrule, commonly deployed in FTTH, enterprise networks, and high-frequency systems.

The difference between UPC (Ultra Physical Contact) and APC (Angled Physical Contact) lies in the shape of the fiber endface:

SC/UPC: Features a flat or slightly convex endface, allowing direct physical contact between fiber cores. It achieves a return loss of approximately >55 dB, suitable for most digital and analog transmission systems

.SC/APC: Features an 8-degree angled endface, which redirects reflected light into the fiber cladding rather than back to the source. This design significantly reduces back-reflection, achieving a return loss of around >55dB, making it ideal for RF, CATV, L-Band satellite, and other high-frequency applications.

Insertion Loss: Both connector types typically achieve 0.3 dB when manufactured correctly, ensuring efficient light transmission

Applications

SC/UPC: Commonly used in Ethernet, GPON, and general digital data systems where moderate reflection control is sufficient

SC/APC: Preferred for analog video, CATV overlays, RFoG, GPS, and other high-frequency or reflection-sensitive system
