Fiber optic joints or terminations are made two ways: 1) splices which create a permanent joint between the two fibers or 2) connectors that mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear.

Either joining method must have three primary characteristics. Fiber optic cables can be joined multiple times in one installation using specialized joints. Joints are used to transfer light from one fiber optic cable to another and are made up of plastic or glass materials. In this article, we will explore the various types of joints in optical fiber. Fiber. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube. Nowadays fiber optic cables are used extensively in network communication and unlike a normal wire joint there are some special joints for fiber optics which are classified below: Types of Joints in Optical Fiber : Splice : It is a joint which is permanent or semi-permanent and can be used only. A fiber optic connector is a mechanical device used to align and join optical fibers, enabling light to pass through with minimal loss.
