Description

[0001] The present invention relates to a multi-channel ferrule polishing apparatus,

The present invention relates to a multi-channel ferrule grinding apparatus, and more particularly, to a multi-channel ferrule grinding apparatus capable of simultaneously grinding a plurality of multi-channel ferrules.

Recently, due to explosive transmission capacity increase, the construction of the high-speed information communication network has been promoted as a national project. The major technology trend of the high-speed information communication network is the DWDM (Dense Wavelength Dvivision Multiplexing) optical communication network. In DWDM transmission, different wavelengths are multiplexed and transmitted in a single optical fiber, and signals are separated and demultiplexed according to wavelengths at the receiving end. Splitter and DWDM flat waveguide are core devices required for DWDM transmission.

An optical fiber array in which a plurality of optical fibers are bonded and integrated is essentially used as an input / output end connection element of a DWDM flat panel waveguide. Since the optical fiber array plays a very important role in the optical communication device, the transmission efficiency is improved by precisely manufacturing the optical fiber array.

The optical fiber arrays also function as connectors interconnected to connect the optical fibers, and the surfaces of the optical fiber arrays connected to each other require optical and precise grinding operations to minimize connection loss.

The optical polishing operation has a very precise flatness of the polishing surface so that when the optical fiber arrays and the like are connected to each other, the interface is completely in contact with each other without gaps.

Then, when the optical signal passes through the boundary surface, the roughness of the polished surface causes the optical signal to have a precise roughness so as not to cause scattering loss of the optical signal.

However, when a plurality of ferrules are simultaneously polished, the conventional ferrite polishing apparatus has difficulty in manufacturing ferrules of the same quality because the polishing surfaces have different flatness depending on the position of the ferrules to the polishing plate.
