Main carriers of the optical fiber as communication, usage amount increasingly increase；Optical fiber is mainly used in field of signal transmissions at present,
Such as mobile phone signal, TV signal, control signal, monitoring signal, currently used optical fiber is silicon dioxide optical fiber, optical fiber
Main part of losing be fibre core, for core diameter usually at 9 μm or so, the core diameter of multimode fibre is commonly 50 μm and 62.5 μ
m；Also there is covering outside fibre core, there is coat outside covering.Since the core diameter of optical fiber is relatively thin, and in air or water
In contain a large amount of hydrogen ion and hydroxide ion, be easy combined with silica, cause fibre core fracture or perhaps optical fiber
Fracture, influence the transmission of optical signal.For this purpose, constantly being studied and having been protected around protection optical fiber in optical cable industry, such as
Optical fiber is contacted with ointment, so that optical fiber is immersed in ointment, it is made to be isolated with moisture, thereby realizes protection.But this side
Formula, on the one hand needs a large amount of ointment, the use of ointment cause the pollution of environment, resource significant wastage, cause cost
It is high；More very, it will usually optical fiber is placed in Loose tube, fiber paste is filled in Loose tube, then by external Loose tube
Surrounding also fills greasy for preventing water, and moisture is further isolated.The increasing of cost is caused, moreover, ointment environment is unfriendly, when use
Therefore more difficult removal all brings great inconvenience to production manufacturer and user.It is therefore expected that the light without ointment filling
Cable occurs, although there is the production of dry type/half dry type optical cable to report both at home and abroad, dry type refers to being not filled with ointment, and use and block water
Powder, the filling of water blocking yarn substance；Half dry type refers to being filled using ointment in Loose tube, in cable core using water-proofing powder or water blocking yarn or
Other substance fillings that block water.Also need to pay more cost, and for the filling in Loose tube in industry, with ointment
When, it is desirable that for filling plumpness 95% or more, this greatlys restrict speed of production and production efficiency.
