Description
Technical field
The present invention relates to a kind of ferrule device, especially a kind of ferrule device that has air discharge duct belongs to the technical field of fibre junction.
Background technology
In the fibre junction field, the mechanical type fibre junction is two kinds of different modes realizing that optical fiber is fixedlyed connected with Fusion Joining.Fiber to the home be deployed in user resident and indoor at the fibre junction point have big and the characteristics that the place disperses of number of users.Because different user is applied to install asynchronism(-nization), same sub-district, similar ADSL service release.After the user arrived to a certain degree, existing workmen and heat sealing machine can not satisfy the time requirement of user's turn up service.Mechanical type fibre junction mode is because simple to operate, and the staff training cycle is short, and instrument is invested characteristics such as little, for the optical fiber large scale deployment provides most cost-effective fibre junction solution.In such as corridor eminence, small space, illumination is not enough, on-the-spot power taking inconvenience etc. occasion.The mechanical type joints of optical fibre provide convenience, practicality, the means that continue efficiently for design, installation, maintainer.In theory, in Fiber to the home engineering, to the family, continuing of the optical cable of registering one's residence of enormous amount, scattered distribution such as capillary all should consider to use the mechanical type joints of optical fibre after the optical splitter beam split.
Optical fiber cold joint technology is guardian technique in optical fiber is registered one's residence engineering, but the insertion loss of optical fiber cold joint product is the resistance for fear of this technology popularization always.Generally the Insertion Loss requirement to the common joints of optical fibre is less than 0.3 or 0.2; Certainly the insertion loss of cold joint product can be more satisfactory state below 0.3 or 0.2.But external domesticly seldom have several companies the insertion loss of cold joint product really can be controlled at below 0.3 or 0.2, and the real insertion loss of this series products of other companies is all at 0.5～0.6.Like product adopts the design of V-type groove mostly, and two ends optical fiber is docked in groove.
The too high The key factor of cold connector Insertion Loss is the low-refraction that the breakpoint place has the clearance to cause.A lot of companies only consider at the breakpoint place when product design and add the matching fluid secluding air, and do not consider the air emptying that how breakpoint place itself is existed, matching fluid wraps up the original micro-air in breakpoint place when using easily, causes insertion loss to maintain about 0.5.
Summary of the invention
