Difference between APC and UPC Connectors
The two acronyms, APC and UPC are relatively common in the fiber optic industry. Even though these two terms are closely related, there are major differences that distinguish the two from one another.
Each of these terms has to do with how a fiber connector endface has been polished. The term APC stands for angled physical contact and UPC stands for ultra-physical contact. As the names imply, these two polishing styles are completely different, which can be witnessed through their results.
APC and UPC Connector Difference
A UPC polish results in a dome-shaped endface that aids in optimizing the connections between two jacketed fibers. On the other hand, the endface on an APC connector is polished at an eight degree angle, which reduces the amount of light reflected between the two connected fibers.
Return loss, or the amount of light reflected back to the original source varies between these two connectors. The angled polish on an APC connector minimizes this loss whereas a UPC connector reflects the light straight back to the source.
A simple way to visually distinguish the two is by remembering that APC connectors are always green. Choosing the appropriate connector for a fiber network depends on things such as, network design and function.
