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: the divisional application of the patent of invention that October 05, application number in 2014 are 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; Optical fiber mainly uses in field of signal transmissions at present, as mobile phone signal, TV signal, control signal, prison Kong signal etc., conventional optical fiber is silica-based optical fiber at present, optical fiber mainly lose part be fibre core, core diameter is conventionally in 9 μ m left and right, and that the core diameter of multimode fibre is conventional is 50 μ m and 62.5 μ m; Also have covering outward at fibre core, covering has coat outward. Because the core diameter of optical fiber is relatively thin, and in air or in water, contain a large amount of hydrogen ions and hydroxide ion, easy and silica bound, causes the fracture of fibre core or perhaps the fracture of optical fiber, affects the transmission of optical signal. For this reason, in optical cable industry, carry out constantly research and protection around protection optical fiber, as optical fiber is contacted with ointment, optical fiber has been immersed in ointment, itself and moisture are isolated, so just realized protection. But this mode, needs a large amount of ointment on the one hand, the use of ointment has caused the pollution of environment, the significant wastage of resource, has caused cost high; More very, conventionally optical fiber can be inserted in loose sleeve pipe, in loose sleeve pipe, fill fine cream, then outside loose sleeve pipe also be filled to greasy for preventing water around, further isolate moisture. Caused the increasing of cost, and ointment environment is unfriendly, more difficult removal when use, therefore, has all brought great inconvenience to production manufacturer and user.
For conventional optical cable, be loose fine structure, multifiber is placed in a loose sleeve pipe, if desired increase the message capacity of optical fiber, need stranded many loose sleeve pipes, form cable core, then form optical cable. Another kind of mode is in the time needing the optical cable of larger core number, conventionally multifiber is put into band, form fibre ribbon, then multifiber band is realized by stacked mode, then shoestring is put into loose sleeve pipe, factice for filling or other suitable material that blocks water in the gap of pine sleeve pipe, reach the function of optical cable water-blocking.
Obviously, the application of ointment has also caused 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 that dry type material water-proof material and optical fiber or fibre ribbon are put together, reach the object blocking water, and obviously, this block-water effect is also irrational principle.
