APC connector loss

Fiber optic patch cord knowledge brief Published 09 Jan 2024

Prepared for preliminary research by the JEWELBLU OPTICAL knowledge desk. Confirm connector types, fiber grades, polish, loss budgets and installation requirements against current standards and product documentation.

Industry standards recommend that UPC connector return loss should be -50 dB or greater, while APC connector return loss should be -60 dB or greater. Remember, return loss is different than insertion loss, which refers to the amount of optical power lost through a connector or. The insertion loss and return loss are exactly measuring the optical fibers' performance. The shapes of optical fiber end faces have mainly. While many factors influence these losses, the type of fiber optic connector used plays a crucial role. Like illustrated in the following picture. Because of the angle, the reflected light does not stay in the fiber core but instead leaks out into the cladding. Compared to UPC connectors, APC interfaces are more tolerant of contamination and end face geometry deviations. The choice between them affects back reflection, insertion loss, network performance, and long-term reliability, especially in PON, backbone. APC connectors feature a fiber endface that is polished at an eight-degree angle; UPC connectors are polished with no angle.
