Description
Technical field
The utility model belongs to the communication apparatus technical field, relates to optical cable, especially relates to a kind of improved local area network optical cable.
Background technology
Optical cable is widely used in communication technique field, and communication has significant effects to its performance to data.Existing optical cable usually is subjected to various mechanical external force effects in processes such as installation and use, comprise pulling force, extruding force, puncture force etc.Because the effect of these external force, cable are in use, the easiest being damaged.Traditional optical cable generally adopts phosphatization steel wire or phosphatization steel band to twine braiding as reinforcement between sandwich layer and outermost sheath.Though this mode can have than hard intensity, also has following shortcoming: subject to thunderbolt; Can make optical fiber suffer hydrogen loss because of the oxidation of phosphatization steel wire or steel band, thereby cause the loss of optical cable significantly to increase; Influence is used under the environment of strong-electromagnetic field.
In order to improve the performance of cable, people have carried out long-term exploration.Chinese patent literature discloses a kind of optical cable [application number: CN200820217353.7], has optical fiber, optical fiber is provided with the stainless steel sleeve pipe outward, optical fiber penetrates and constitutes optical fiber bundle tubes in the stainless steel sleeve pipe, stainless steel sleeve pipe outer wall is stranded the reinforcement steel wire, strengthen steel wire and be with sheath outward, sheath forms by the organdy establishment and with the polyimide resin dip-coating.This optical cable is a beam tube type cable, in the time of can guaranteeing that optical cable is crooked, and the deformation minimum that optical fiber bundle tubes bears; Sheath forms by the organdy establishment and with the polyimide resin dip-coating, and optical cable is had favorable mechanical and chemoproection effect, can work in-180 ℃～+ 300 ℃ temperature ranges; Utilize in the stainless steel sleeve pipe towards inert gas or the optical fiber that increases the carbon sealant this optical cable is used under the environment of special humidity, and avoid the effect of invading of moisture and hydrogen optical fiber.The somebody has invented a kind of flexible optical cable [application number: CN200920042217.3].It has optical fiber and oversheath, also have the spirality metal flexible pipe that turns to by stainless steel sheet|, penetrate at least two optical fiber in the metal hose, and the outer hard-pressed bale of optical fiber there is cushion, metal hose is outside equipped with the braid that is formed by steel wire or organdy braiding, and braid coats oversheath outward.
Though such scheme has improved the performance of optical cable to a certain extent, still exist complex structure, the manufacturing cost height is easy to be struck by lightning, and physical strength is the high-technology problem not.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, simple in structure, can be struck by lightning long service life, physical strength height, and the improved local area network optical cable of being convenient to discern.
For achieving the above object, the present invention has adopted following technical proposal: this improved local area network optical cable, comprise central reinforce member and some cable core bundles, be with a loose sleeve pipe respectively in the periphery of every cable core bundle, described loose sleeve pipe is stranded around central reinforce member, it is characterized in that, described central reinforce member is made by nonmetallic materials, the periphery of described loose sleeve pipe is provided with the reinforcing sleeve of being made by nonmetallic materials that each loose sleeve pipe is tied, between reinforcing sleeve and loose sleeve pipe, be provided with the fine cream of going along with sb. to guard him loose sleeve pipe, periphery at reinforcing sleeve is provided with sheath, and the lateral surface of described sheath is provided with the axially extended mark structure that has with the sheath different colours.
In above-mentioned improved local area network optical cable, described reinforcing sleeve is formed by the aramid yarn coiling.
In above-mentioned improved local area network optical cable, described reinforcing sleeve is formed by the organdy coiling.
In above-mentioned improved local area network optical cable, described mark structure comprises at least one axially extended colour code band.
In above-mentioned improved local area network optical cable, described colour code band and sheath are connected as a single entity structure.
As another kind of scheme, in above-mentioned improved local area network optical cable, described colour code band and sheath split are provided with, and the colour code band is embedded at jacket outer surface.
In above-mentioned improved local area network optical cable, described colour code has two and be arranged on jacket outer surface symmetrically.
Compared with prior art, the advantage of this improved local area network optical cable is: 1, reasonable in design, simple and compact for structure, the physical strength height can effectively prevent the external force invasion, and owing to the reinforcement structure that adopts nonmetallic materials to make, can be struck by lightning.2, can not make optical fiber suffer hydrogen loss because of the oxidation of phosphatization steel wire or steel band, thereby cause the loss of optical cable significantly to increase.3, under the environment of strong-electromagnetic field, also can use, moistureproof, anti-ly open, lateral pressure resistant and strong shock resistance.4, be easy to identification, handled easily uses.
