Use of Fiber Optic Polishing Machines in polishing fiber-optic connectors

The end faces of fiber optic products (cables, connectors, adapters, etc.) are polished by fiber polisher machines so that signal losses can be minimized that take place due to scattering. The connector is an important step in the whole fiber optic polishing process. There is an increase in insertion loss and reflection by bad polished connectors which will ultimately result in malfunction.

Optical performance is highly influenced by polishing the fiber/ferrule end faces of a fiber-optic connector and it is highly susceptible to error. Still, the polishing process is neither difficult nor mysterious. In the final step, fiber is optically prepared with the help of polishing so that it can make sure that the defects and non-uniformities in the end faces of fiber or geometry do not degrade the passage of light across the connector joint.

Within a precision ferrule, a fiber-optic connector has the fiber placed, which is made of ceramic, stainless steel, or polymer. After cleaving, polishing removes excess epoxy or fiber stub that is left, it even shapes the ferrule, and also removes the scratches present in the glass. 

There are various features that you need to consider while choosing a fiber polishing machine there. These consist of changeable holders, a timer, adjustable pressure, and the ability to request custom specifications.

Polishing machines are available with adjustable pressure. This is necessary because of the loading pressure and the hardness of the polishing surface the fiber connector's finished end-face geometry is generated. The polishing pressure should be adjustable with clearly marked divisions of measurement so that it can optimize the connector end face. The connector is an important step in the whole fiber optic polishing process.

In the polishing machine, there is a must requirement of changeable holders so that one machine can be used for many connector types. 

During connector and fiber manufacture the first two factors are determined and during connector termination, they are beyond control. By fiber polishing fixture the last two factors are directly influenced. The end finish is necessary because scratches, fractures, and other imperfections present to prevent the maximum transfer of optical power between the two joining fibers.
