Abstract
The invention provides a process for packaging a high air-sealed fused-tapered fiber coupler. The process comprises the following steps: cutting fibers; tapering the cut fibers on a tapering machine to sinter several fibers together, and monitoring the splitting ratio or wavelength of the fibers in the tapering process; when the splitting ratio or wavelength meets the technical index, packaging the sintered fibers with quartz tube dispensing; roasting the product which is packaged with the quartz tube, respectively enabling two ends of each fiber to pass through pores of hollow cylindrical plugs, and adding a drying agent into pores of the hollow cylindrical plugs to complete an end socket; and finally, covering a stainless steel sleeve outside the end socket, and carrying out silica gel filling. According to the process, the air sealing performance can be improved by matching tolerance tightness of machine dimension assembly among structural parts and additionally placing a moisture-proofing material during packaging, so that the service life of a product at a temperature of 85 DEG C can be over 2000 hours, and the application range of the fiber coupler can be enlarged.
Description
Technical field

The packaging technology of close property fused biconical taper fiber coupler.
Background technology
Optical network system needs optical signal is carried out coupling, branch, distribution, this is accomplished by fiber coupler to realize.Light
Fine bonder, also known as optical branching device, beam splitter, is one of most important passive device in optical fiber link, is to be only second to optical fiber connection
The important passive device of device, which has the optical fiber tandem device of multiple inputs and multiple outfans.Conventional M × N is representing
One shunt has M input and N number of outfan.Optical branching device used in Optical Fiber CATV System is typically all 1 × 2,1
× 3 and 1 × N optical branching device for being made up of them.
The production method of fiber coupler has fused tapered, micro-optic formula (MICRO Optics), light wave conduction (Wave
Guide) three kinds.For wherein fused tapered is simple, an exactly class can make the optical signal of transmission, in special construction area, coupling occur
Close, then the device for carrying out energy distribution.The main method of its technique be by two or more pieces optical fiber and together using high temperature
Oxyhydrogen flame burns and melts stretching, so that core is polymerized together, according to different CGCMs so as to realize the distribution of energy.Fused tapered light
Fine bonder has become new number monitoring in light path, and the main devices of energy distribution, because manufacture method is simple, low price, temperature
The advantages of characteristic is good, becomes the main flow manufacturing technology in market at present.
The manufacturing process of the product of existing fiber bonder can be divided into two steps, and the first step is to burn to melt by high temperature oxyhydrogen flame
The distribution of energy or wavelength is realized in stretching, and second step is exactly to encapsulate, i.e., the optical fiber for the first step being drawn is sealed with some casing protections
Load so that product has certain air-tightness.The detailed process of its encapsulation is firstly the need of using quartz ampoule or glass tubing handle
Burn the fiber optic protection after drawing well to get up, and installed with mucilage sealing at two of protection pipe, then cover a stainless pipe pipe outside again,
Protected with silicone filler, be so only a complete device.
Due to fiber to the home, the application expansion of fiber optic communication in recent years, the applied environment of product also becomes increasingly complex, ring
Border is more and more severe, high and cold or Haiti.This waterproof just to product encapsulation, the higher requirement of air-tightness proposition, and traditional envelope
Dress technique causes product meet the requirement in 85 degree of 2000 hour life-spans of humidity.
Content of the invention
The present invention is for the problem of prior art presence, there is provided a kind of envelope of high-air-tightness fused biconical taper fiber coupler
Dress technique.
