Features of PC-type fiber optic connectors

PC (Physical Contact) fiber optic connectors feature a slightly convex ferrule end face that ensures direct fiber-to-fiber contact, reducing air gaps and minimizing optical return loss.Design and StructurePC connectors are designed with a slightly convex or spherical end face on the ferrule, which allows the fiber cores to make direct contact when mated. This design reduces the air gap between fibers, which is a common source of signal reflection and loss in flat-ended connectors. The convex shape ensures that the highest point of the fiber core touches first, improving alignment and light transmission efficiency .Optical PerformanceThe return loss of PC connectors is typically around -40 dB in single-mode applications, which is significantly better than older flat polish connectors (-14 dB). This reduction in back reflection improves signal quality and reduces interference in optical networks . However, compared to UPC (-50 dB) and APC (-60 dB) connectors, PC connectors have higher return loss, making them less suitable for high-speed or sensitive applications .ApplicationsPC connectors were widely used in OM1 and OM2 multimode fiber systems and in general telecom equipment. They are suitable for applications where moderate performance is acceptable, such as standard data transmission and legacy networks. Over time, PC connectors have been largely replaced by UPC and APC connectors in high-performance systems due to their superior return loss and lower back reflection .LimitationsHigher return loss compared to UPC and APC connectors, limiting their use in high-speed or long-distance networks.Surface degradation can occur with repeated connections and disconnections, affecting performance over time.Obsolescence: Modern networks often prefer UPC or APC connectors for improved optical performance . In summary, PC-type fiber optic connectors provide a basic physical contact design that reduces air gaps and improves signal transmission, but they are now mostly superseded by UPC and APC connectors in high-performance optical systems due to their higher return loss and limited suitability for sensitive applications .
