What is Differences SC UPC vs. SC APC Fiber Patch Cords and Their Losses

Basics of Fiber Optics Connectors

• Connector Types: Explain that SC (Subscriber Connector or Standard Connector) is a common type of fiber optic connector.
• UPC and APC Explained: Define UPC (Ultra Physical Contact) and APC (Angled Physical Contact) and how they differ in terms of the end-face polish of the connectors.

SC UPC Fiber Patch Cords

• Description: Describe the physical characteristics of SC UPC connectors, noting their flat, polished surface.
• Performance and Loss: Discuss how the flat end-face impacts light reflection and transmission, leading to certain levels of insertion loss and back reflection.

SC APC Fiber Patch Cords

• Description: Describe the physical characteristics of SC APC connectors, highlighting their angled, polished surface.
• Performance and Loss: Explain how the angled end-face reduces back reflection more effectively than flat surfaces, thereby reducing insertion loss and enhancing signal quality.

Comparing SC UPC and SC APC

• Physical Differences: Emphasize the visual differences in end-face polish and color coding (typically, green for APC and blue for UPC).
• Performance in Network Applications: Discuss which situations or types of fiber networks each is better suited for, based on their back reflection and insertion loss characteristics.
• Application Specifics: Provide examples of where each type is commonly used, such as SC APC being favored in high-bandwidth video transmissions and SC UPC in general data communications.
