A fiber optic connector is a device used to connect two optical fibers. It works by connecting the ends of two fibers so that their optical signals can be transmitted to the other fiber. Its main components include the connector itself, the fiber optic termination attached to the connector and the connector's accessories.
Its working principle mainly includes the following steps:
1. End-face alignment: First align the ends of the two fibers to ensure that the distance and angle between them are correct. This is a critical step to ensure that the optical signal can be transmitted.
2. Contact detection: The connector usually contains a contact detection mechanism to detect whether the end faces of the two fibers are in proper contact. This mechanism can determine the contact status by measuring the intensity of the reflected light.
Endface cleaning: To ensure the quality of optical signal transmission, the connector endface needs to be kept clean. Therefore, the end face of the fiber needs to be cleaned to remove dirt and impurities before connecting the fibers.
4. Optical signal transmission: Once the connector end face is aligned, in good contact and clean, the optical signal can be transmitted through the fiber optic connector to another fiber. This is due to the design of the connector that allows light to travel along the axis of the fiber and there is no significant loss between the two fibers.
In summary, fiber optic connectors work by ensuring that the fiber is aligned, in good contact, clean, and designed so that the optical signal can be transmitted to the other fiber, thus allowing the connection of two fibers.
