The Difference Between UPC and APC Connectors

Knowing the difference between UPC (ultra physical contact) fiber endface connectors and APC (angled physical contact) fiber endface connectors can help you make sure that your optical networks are running properly. In this blog post, we will explain the differences between these two types of singlemode fiber connectors, as well as discuss why they are important in testing.

Blue singlemode connectors feature a UPC fiber endface, while green singlemode connectors feature an APC fiber enface. With a UPC connector, the fiber endface is a slightly rounded surface. This means that when light is transmitted through it, there is very little reflected light because the surface has no sharp edges to bounce off of. On the other hand, the endface of an APC connector is slanted 8 degrees. This angle causes reflected light to be angled away from the source rather than bounced back towards it, which reduces signal noise and improves overall transmission quality.

The shape of the connector also affects how easily it can be inserted into another device or port. UPC connectors have a flat surface that allows them to be inserted easily without any force or resistance, however APC connectors have a slanted surface which requires more pressure to insert them correctly. Because of this difference in insertion methods, it’s important to know what type of connector you are dealing with before attempting to connect any cables or devices together – otherwise you could damage your equipment or cause cross-talk interference with other connected devices.

In terms of testing, both types of singlemode fibers work well for different applications – UPCs provide better performance in short distance connections such as patch cords and jumpers while APCs provide better performance over longer distances like those found in data centers or backbone networks due to their improved signal integrity. Additionally, APCs typically require different test instruments than those used for testing UPCs so it’s important to make sure you’re using the right tools for each job – otherwise your results could be inaccurate or misleading.

In conclusion, understanding the difference between UPC and APC singlemode fiber connectors can help ensure that your optical networks are running properly and efficiently. By knowing which type of connector you need for each application, you can ensure that you are using compatible equipment and performing accurate tests on your system – leading to reliable results every time! Whether you’re working with patch cords or large data centers, understanding these differences will help keep your optical network running smoothly!
