APC – Angled Physical Contact

An Angled Physical Contact (APC) connector is a type of connector with an angled tip designed to reduce insertion loss in data and communication systems. It is typically used in fiber optic and optical networks, as well as other communication systems, to connect two cables together. The APC connector has an angled tip that is designed to minimize the reflection of light back into the fiber, reducing the amount of light lost when a signal passes through it. This minimized reflection of light also reduces the amount of noise or interference in the signal, resulting in a cleaner, more reliable connection. The angled tip of the APC connector is typically 8 degrees, compared to the standard PC connector which has a tip angle of 0 degrees. This 8-degree angle allows the light to enter the connector at a shallow angle, which reduces the amount of light that is reflected back into the fiber. This allows for a higher-quality connection with less loss of signal. The APC connector is typically used in long-distance communication systems, where a high-quality connection is necessary for reliable data transmission. It is also used in applications where a low-loss connection is required, such as in fiber optic networks, or in optical networks. The angled tip of the APC connector gives it an advantage over traditional PC connectors, as it helps reduce insertion loss, resulting in a more reliable connection and better performance. Although the APC connector is more expensive than the PC connector, its superior performance makes it worth the extra cost.
