Description
The application is that name is called: matrix material and adopt the fibre ribbon of this resin and optical cable, the applying date to be: on October 05th, 2014, application number are the divisional application of the patent of invention of 201410519527.5.
Technical field
The invention belongs to material and technical field of cables, especially relate to matrix material and adopt fibre ribbon and the optical cable of this resin.
Background technology
Optical fiber is as the main carriers of communication, and use amount increases day by day; Current optical fiber is mainly used in field of signal transmissions, as mobile phone signal, TV signal, control signal, prison Kong signal etc., optical fiber conventional is at present silica-based optical fiber, optical fiber mainly lose part be fibre core, core diameter is usually at about 9 μm, and what the core diameter of multimode optical fiber was conventional is 50 μm and 62.5 μm; Also there is covering outward at fibre core, outside covering, there is coat.Because the core diameter of optical fiber is relatively thin, and contain a large amount of hydrogen ions and hydroxide ion in air or in water, easy and silica bound, causes the fracture of fibre core or perhaps the fracture of optical fiber, affects the transmission of light signal.For this reason, carried out constantly research and protection around protection optical fiber in optical cable industry, as contacted with ointment by optical fiber, having made optical fiber be immersed in ointment, itself and moisture being isolated, so just achieves protection.But, this mode, need a large amount of ointment on the one hand, the use of ointment causes the significant wastage of the pollution of environment, resource, causes cost and remains high; More very, usually can optical fiber be inserted in Loose tube, in Loose tube, fill fine cream, then also fill greasy for preventing water by around the Loose tube of outside, isolate moisture further.Cause the increasing of cost, and ointment environment is unfriendly, more difficult removal during use, therefore, all brings great inconvenience to production manufacturer and user.
For conventional optical cable, be loose fine structure, multifiber be placed in a Loose tube, if desired increase the message capacity of optical fiber, then need stranded for many Loose tube, form cable core, then form optical cable.Another kind of mode is when needing the optical cable of larger core number, usually multifiber is put into band, form fibre ribbon, then plurality of ribbons is realized by stacked mode, then shoestring is put into Loose tube, in the gap of Loose tube, factice for filling or other suitable material that blocks water, reach the function of optical cable water-blocking.
Obviously, the application of ointment also result in the increase of cost, the pollution of environment, the difficulty of construction.Although also there is at present both at home and abroad the structure of so-called Full-dry optical cable, they are put together at dry type material water-proof material and optical fiber or fibre ribbon, reaches the object blocked water, obviously, this block-water effect principle be also irrational.
