To put it simply pc upc and apc refer to the polish styles of the ferrules inside the fiber optic connectors just as the following figure shows the ferrule is the housing for the exposed end of a fiber designed to be connected to another fiber or into a transmitter or receiver.
Apc vs upc fiber connectors.
They have a slight curvature for better core alignment.
Upc connectors are polished with no angle.
Sc apc vs sc upc with the rapid development of fiber networks fiber connectors have become an essential assembly to cater for high performance fiber optic system.
The main difference between upc and apc connector is the fiber end face.
Currently with upc and apc connectors dominating the market these two types are the most commonly seen connectors employed in the fiber optic industry.
Differences between upc and apc.
With upc connectors any reflected light is reflected straight back towards the light source.
Upc connectors are not exactly flat however.
The main difference between apc and upc connectors is the fiber endface.
There are various fiber connector types in the market such as lc st sc mpo mtp and so on among which sc is one of the most commonly used fiber connectors.
Apc connectors feature a fiber endface that is polished at an eight degree angle.
Introduction to different connector types.
Upc connectors are polished with no angle but apc connectors feature a fiber end face that is polished at an 8 degree angle.
This means that whilst a upc polished connector will be okay for a variety of optical fiber applications only an apc will cope with the demands of complex and multi play services.
