End finish is the term used to describe the quality of the end surface of a fiber or cable that has been prepared for splicing or termination in a connector. The end finish of a fiber or cable is an important factor in successfully joining two cables together, as it affects the electrical and optical performance of the connection.
The end finish of a fiber or cable must be as smooth and as flat as possible in order to ensure a strong, reliable connection. This is especially important in optical fiber applications, as the end finish of the fiber must be perfect in order to allow light to be transmitted from one end to the other without interruption. In order to achieve this, the end of the fiber must be polished, which can be done either manually or with automated machines.
The end finish of a cable or fiber must also be free of dirt, dust, and other contaminants in order to ensure that it can be properly connected and sealed. This is especially important in the case of connectors, as they must be able to make a tight, secure connection. Other factors to consider include the precise shape and size of the end finish, as this will affect the type of connector that can be used.
In summary, end finish is an important part of the cable and fiber preparation process. It is the quality of the end surface of the cable or fiber that has been prepared for splicing or termination in a connector. In order to ensure a strong, reliable connection, the end of the fiber must be polished and free of dirt and dust. The precise shape and size of the end finish must also be taken into account in order to ensure that the correct type of connector can be used.
