What are the connection methods for optical cables and fiber distribution boxes
Joining fiber optic cables is typically done through splicing, which can be mechanical or fusion. Mechanical splicing involves aligning the fiber ends and using a connector to hold them together, while fusion splicing uses heat to fuse the fiber ends, creating a continuous fiber. Some connectors commonly used in optical fiber connection in optical fiber links, such as: optical fiber distribution frame, terminal box, fiber distribution box, ODF distribution frame, what are the differences between them, let's take a look below. The functions of the four connectors can be.
