Abstract: A high performance quick terminal assembly comprises a first ferrule and a second ferrule connected as a whole by a connecting element. The first ferrule and the second ferrule are respectively provided with an inner bore. A gap is provided in the middle of the second ferrule to expose the inner bore, forming a connecting platform for connection of pre-embedded optical fiber and connecting optical fiber. A pressing device is provided at the connecting platform to compress the connecting point of the pre-embedded optical fiber and the connecting optical fiber. The first ferrule and the second ferrule are common ceramic ferrules. By combination of the first ferrule and the second ferrule, it replaces the conventional ceramic ferrule. Consequently, excellent optical performance and high reliability are achieved, and the production costs are largely reduced and versatility is improved.

Abstract: A ceramic ferrule made of a complex Zircornium oxide base material which blends with a rare element, such as Yuttrium, Cerium, etc, is provided. The ceramic ferrule can increase the phase transition resistivity of the Zircornium oxide material. It has a precise construction, and the reliability of products is enhanced. 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.
