The PC Polish Fiber Optic Connector uses a Physical Contact (PC) polished ferrule end face to provide reliable optical fiber interconnection. The PC polishing process creates a slightly curved fiber end face so that the fiber cores make physical contact when two connectors are mated, helping reduce back reflection at the connection interface.
PC polishing can be applied to different fiber connector formats, including FC, SC, and ST, depending on the equipment and network interface. The connector provides precise fiber alignment through the ferrule and adapter structure and is suitable for optical communication, distribution, test, and equipment interconnection applications.
Depending on the required configuration, PC-polished connectors can be supplied for different fiber types, cable structures, connector housings, and termination requirements.

PC stands for Physical Contact. It describes the polishing geometry of the connector ferrule end face rather than the connector housing type. The curved PC end face allows the two fiber cores to make physical contact when connected, helping reduce optical reflection at the interface.
PC, UPC, and APC refer to different fiber end-face polishing methods. PC uses a physical-contact curved surface, UPC uses an improved ultra-polished physical-contact surface, while APC uses an angled polished surface to further reduce reflected light. The appropriate polish type should be selected according to the optical system and equipment interface.
