Apc Vs Upc Fiber Connectors

Introduction to different connector types.

Apc vs upc fiber connectors.

Another more obvious difference is color. Upc connectors are not exactly flat however. With upc connectors any reflected light is reflected straight back towards the light source. 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.

Differences between upc and apc. 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. The main difference between upc and apc connector is the fiber end face. 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.

Currently with upc and apc connectors dominating the market these two types are the most commonly seen connectors employed in the fiber optic industry. Apc connectors feature a fiber endface that is polished at an eight degree angle. Upc connectors are polished with no angle. The choice is even more important where connector ports in the distribution network might be left unused as is often the case in fttx pon network architectures.

They have a slight curvature for better core alignment. Differences between upc and apc connector.
