When we talk about optical fiber jumpers, such as optical fiber jumpers, pigtails, adapters, and splitters, we will refer to the descriptions of UPC or APC. Some customers will wonder, what is LC/UPC - LC/UPC? What is SC/APC - SC/APC? In fact, UPC and APC are two kinds of grinding methods for optical fiber sleeves. Today we will mainly introduce these two different grinding methods so that you can choose the appropriate network center solution.

What is APC&UPC?

When a connector is installed on the end face of an optical fiber, the return loss is inevitable, which is caused by the reflection of the light source. Serious light loss will damage the laser source and interrupt the transmission of signal. Therefore, connector ferrules with different grinding methods can avoid serious return loss to a certain extent. UPC and APC are two widely used grinding types.

UPC, that is, ultra-physical contact, evolved from PC and has better surface finish. UPC connectors rely on machine polishing and have low return loss.

APC, namely angular physical contact. The end face is ground to an angle of 8 degrees, which is inclined to reduce reflection. APC can only be connected with APC. Because the structure of APC is completely different from that of UPC, if the two connectors are connected by flange, the optical fiber end face of the connector will be damaged.
