Angled Physical Contact (APC) is a style of fiber optic connector that is designed to help minimize back-reflection when connecting fiber cables. It uses a 5°-15° angle on the connector tip to reduce the amount of light that is reflected back from the connector. This helps to ensure that the signal is not affected by the connector itself.
In addition to the angled physical contact, APC connectors also feature a ceramic ferrule with a special finish. This helps to reduce the amount of light that is reflected off of the ferrule itself, resulting in a stronger and more reliable signal.
APC connectors are often used in high-bandwidth applications such as Ethernet, data centers, and telecommunications. They are also popular in medical applications, such as endoscopy and imaging.
APC connectors are typically made of plastic, although ceramic or stainless steel versions are available as well. They are usually keyed to prevent accidental mismatching of different APC connectors.
Overall, angled physical contact (APC) connectors are designed to minimize back-reflection while providing a strong and reliable connection. They are easy to install and can be used in a variety of applications, including data centers, telecommunications, and medical applications. Thanks to their angled physical contact design, APC connectors can help ensure that your signals remain strong and clear.
