Today’s high bandwidth broadband connections and RF over fiber are examples of applications that require very low reflections to maintain high quality of service. Angled Physical Connector (APC)Īlthough UPC connectors have low return loss, there are cases where it is not low enough to meet the needs of an application.

The relatively low return loss allows for a more reliable signal for digital TV, telecommunications, and data centers, where UPC dominates the market today. The flat fiber end face reflects light directly back towards the source, resulting in -50dB or lower reflections.

Ultra Physical Connector (UPC)īuilding on the convex end face from the now outdated PC connectors, UPC connectors utilize extended polishing methods which creates a finer fiber surface finish. The UPC connector is usually blue, while the APC connector is usually green. It is generally the goal in communications to have as little return loss as possible.Īnother difference between UPC and APC is the industry standard color. The higher the return loss, the stronger the signal returned. Return loss, expressed in negative decibels (dB), is the measurement that industry experts use to determine how much light is reflected. How the end face is shaped affects how light is reflected.

An APC connector end face has an eight-degree angle while the UPC connector has no angle. The main difference between UPC connectors and APC connectors is the fiber end face. For example, what’s the difference between an LC/UPC connector or an LC/APC connector? Are the two connector types compatible? And finally, what’s the cost-effectiveness of the two?

When talking about fiber optic products like trunk assemblies, patch cords, or single-mode jumpers, eventually UPC connectors or APC connectors will enter the conversation. Ultra Polished Connector (UPC) & Angled Polished (APC) connector: what’s the difference? For this reason, combined to its constantly decreasing manufacturing costs, APC has become the most used polishing type.Guide to Fiber Connector Endface Polish Types: UPC vs APC Published on Apby Jace Waechter The ferrule ends in a plain, 8 degree angled surface making it the connector that achieves a best optical link because it cuts down the return losses up the -60 dB thus allowing increasing the number of users in single mode fibers. The current trend is using it in dead lines to allow operators to perform networks tests for example by using an OTDR. They are similar to the PC connectors, allowing decreasing return losses to a margin between -40 and -55 dB thanks to the sharper curve of the bevel. This avoids empty spaces between the ferrules of the connectors being coupled, and achieves insertion losses among -30 dB and -40 dB. The ferrule is beveled and finished in a plain surface.
