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.
