Embodiment 1

[0031] Insert a 125-micron silica fiber 5 with the coating removed in a ceramic ferrule with a pore size of 127 microns, and fill it with nano-scale SiO by vacuum technology 2 Mixed powder with Au (gold), the mixing ratio is 90:10, SiO 2 And the purity of Au is 99.9%, and the melting point is 1000°C. The preform was placed at 1100°C for 3 minutes and then cooled. Grinding after cooling, the grinding angle is 8 degrees (according to FC / APC requirements) and equipped with a fiber optic adapter with heat dissipation. Through 6W 1550nm single-mode laser (power density reaches 0.1W / μm 2 ), the loss is 0.28dB, after 20 times of plugging and unplugging with light, after 500 hours of long-term connection, the end face of the optical fiber is complete without any burning marks from the microscope.

Abstract

The invention relates to a single-mode fiber connector wire on the basis of an adhesive-free vitrification technology. The single-mode fiber connector wire comprises a silica fiber, a vitrified nanometer-sized silicon dioxide layer and a ferrule. The vitrified nanometer-sized silicon dioxide layer covers the outside of the silica fiber, the ferrule covers the outside of the vitrified nanometer-sized silicon dioxide layer, and nanometer-sized silicon dioxide is vitrified to form the vitrified nanometer-sized silicon dioxide layer. Preferably, the nanometer-sized silicon dioxide is nanometer-sized silicon dioxide with a low melting point, and the melting point is lower than 1500 DEG C. The ferrule is a ceramic ferrule or a metal ferrule or a silica ferrule. The invention further provides the related nanometer-sized silicon dioxide and a manufacturing method for the single-mode fiber connector wire on the basis of the adhesive-free vitrification technology. The single-mode fiber connector wire on the basis of the adhesive-free vitrification technology, the nanometer-sized silicon dioxide and the manufacturing method have the advantages that the single-mode fiber connector wire is smart in design, simple in structure and suitable for large-scale popularization and application, is high-temperature-resistant, is not easy to burn and can bear W-grade single-mode transmission.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to the field of optical fiber jumper technology, and specifically refers to a single-mode optical fiber connector line based on glue-free vitrification technology, related nano-scale silica and a production method. Background technique [0002] From the beginning of optical fiber communication, many kinds of optical fiber connectors have been developed, such as SC / APC, FC / APC, etc. These connectors play an important role between optical fiber communication equipment and equipment, and between equipment and transmission optical cables. However, with the increasing power of communication lasers, the burning of connectors during the connection process is becoming more and more frequent and serious. Especially in the CATV fiber-to-the-home (FTTH) process, the introduction of fiber amplifiers with W-level output power makes this phenomenon more frequent. In many cases, the probl...
