Abstract
A polishing apparatus for polishing optical fibers includes a polishing pad and a polishing arm arranged above the polishing pad and which is selectively brought into contact with the polishing pad. A leveling device is magnetically attached to a lower end of the polishing arm. The leveling device has a plurality of optical fiber ends extending downwardly from a lower surface thereof to contact the polishing pad. The polishing arm also contains a pressure transducer for measuring a pressure applied by the polishing arm when the polishing arm contacts the polishing pad. The magnetic attachment between the polishing arm and leveling device may be carried out using a permanent magnet or electromagnet.
