(57) The present invention relates to a ceramic material preparation technology. The present
invention also relates to optical communication technology, especially to a ceramic
ferrule made of a complex Zircornium oxide base material which blends with a rare
element, such as Yuttrium, Cerium, etc. The ceramic ferrule made of a complex Zircornium
oxide base material which blends with a rare element, such as Yuttrium, Cerium, etc.
provides significant features, such as increasing the phase transition resistivity
of the Zircornium oxide material, having a precise construction, effectively enhancing
reliability of products and having high quality connection, good aging resistance
and good environment adaptability. A movable connector of field-assembled optical
fiber which adapts the present ceramic ferrule not only achieves co-axial joint of
the optical fibers better surface smoothness as compared with plastic ceramic ferrule,
but also overcomes the problem of scratching easily incurred during connection between
plastic materials. The present invention has characters of good aging resistance,
low insertion lose on jointing of optical fibers, high return loss and good connection
quality.
