APC, UPC, PC Fiber Connector Types Comparison
The LC, SC, and FC indicate the different structures of fiber connector types, whereas the UPC and APC indicate different polishing shapes
An SC connector is the termination fitted to the fiber. Its job is to hold the fiber in precise alignment so light transfers across the mating interface with low loss. The format uses a square housing, a 2. While LC has taken over in data centers, SC holds its ground wherever its larger ferrule and snap-in mechanism offer practical. Understanding fiber connector types—SC/APC, SC/PC, LC/UPC, LC/APC, ST/PC, FC/PC, and FC/APC—is essential for selecting the right interface for your application. Each type varies by shape, polish (APC, PC, or UPC), and return loss performance, which affect PC, UPC, and APC Polish Styles: What's the. SC (Subscriber Connector / Square Connector) is larger than LC an...
