The bending property of unit and lateral pressure resistant performance, make it have certain fire resistance simultaneously.
The manufacture method of the optical cable in embodiment 2 is identical with embodiment 1.
In embodiment 1-2, its light unit of the easily branched optical cable of large core number high-performance optical unit uses new material and special
Optical fiber, fine cream fill process so that the bending property of light unit and lateral pressure resistant performance are improved that to make it possess certain simultaneously
Fire resistance, as light unit produces more than 12 modes that can use spray printing colour circle, is conveniently identified distinguishing, large core number
Optical cable reaches purpose easy to identify.Using novel coagulation type fibre cream in sleeve pipe, when ensureing vertical wirings, fibre cream is without the situation of drip,
By using the oil-filled mould of particular design, four holes using 4 optic fibre separations to penetrate oil-filled needle tubing enter together with fine cream
Sleeve pipe is interior thus ensures that optical fiber is uniformly distributed in Loose tube and then reaches to protect optical fiber and the purpose blocked water to also achieve simultaneously
The features such as the fiber packing density required by branched cable is high, cable footpath is little, lightweight.Use when additionally protecting outside it is placed in parallel
The structure of FRP makes outer layer optical cable have load carrying unit, support unit, can improve optical cable overall mechanical properties, environmental performance
Effectively preventing Radio frequency interference and Electromagnetic Interference, external sheath layer uses double-colored bar technique to solve the FRP's that is placed in parallel simultaneously
Orientation problem, can effectively avoid FRP during follow-up stripping branch and facilitate stripping, is made by the increase of light unit inner fiber core number
The reduction of the cable size of same light fibre core number reduces production and the later maintenance cost of optical cable.Large core number high-performance optical unit
Easily branched optical cable is the optimum selection of high-rise building wiring optical cable.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.
Multiple amendment to these embodiments will be apparent from for those skilled in the art, as defined herein
General Principle can realize without departing from the spirit or scope of the present invention in other embodiments.Therefore, the present invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and features of novelty phase one
The widest scope caused.
