Beneficial effect:
The present invention adopts tight tube fiber structure, outer jacket adopts steel bonding oversheath, adopt novel structural design and technology controlling and process simultaneously, not only ensure that optical cable has outside conventional remote radio head properties of optical fiber cable, realize conducting function after adopting special process steel band can ensure to peel off without coat to strengthen, lead thunder and lightning and rodent-proof characteristic improvement, convenient and quick construction simultaneously, greatly reduce construction period and construction cost.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present invention.
Fig. 2 is process chart of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
See figures.1.and.2, the present invention includes cable core, cable core is by outer cladding tight sleeve layer 2 successively after optical fiber 1 coloring treatment, subelement stiffener 3 and subunit jacket 4 are formed, subelement stiffener 3 is aramid fiber reinforcement, stranded coated low smoke and zero halogen inner sheath 7 after 2 cable cores and 2 reinforcements 6 are intervally arranged, 2 reinforcements 6 adopt gasket for packing, low smoke and zero halogen inner sheath 7 outer cladding is peeled off force value and is controlled at the steel band 8 of 2-4N/cm and steel bonding oversheath 9, steel bonding oversheath 9 adopts low stripping rate steel outer protective polyethylene cover, the cohesive force of steel band 8 and steel bonding oversheath 9 meets the twisting test of positive and negative 180 degree of torsions 10 times.
As further improvement, many cable cores can line up a circle, and the heart arranges the rear stranded coated low smoke and zero halogen inner sheath 7 of gasket for packing reinforcement 6 wherein.
The present invention utilizes existing conventional structure as remote radio head light unit, both can meet Customer Standard accessory and to have continued problem, company's existing resource can be utilized again to carry out production.
The present invention is wireless base station remote radio optical cable unit, is laid in Base Band Unit BBU to wireless radio remote unit (RRU) therebetween, realizes a BBU and supports multiple RRU.Adopt BBU+RRU Multi channel.
Because optical cable need extend to tower top, and in optical cable, have metal tape to exist, therefore be very easily struck by lightning, cause the damage of base station equipment, therefore, need optical cable to carry out grounding, therefore in use, tower top section is directly connected with emitter by the steel band in optical cable, reaches conducting function, so outer the protecting of optical cable must be divested.
The requirement of conventional outdoor communication optical cable is that the cohesive force of PE protective cover material and steel band is more high better, but just causes when stripping sheath like this, and extremely difficulty divests, and therefore needs the adhesion problem between emphasis solution sheath and steel band for this kind of optical cable.
The present invention increases steel bonding oversheath outward at conventional remote radio head optical cable unit cable, utilize iron and steel conductive characteristic, after oversheath is peeled off, steel band is docked separately with the conducting end of other positions as conducting metal, before it enters machine room, a grounding is done to feeder line outer jacket, most of lightning current is directly introduced machine room earth mat, thus decreases the thunder energy entering machine room.But fully stripped state between steel band and PE protective cover material (namely after stripping outer jacket, steel band overlay film is also with completely and is removed, only remaining base steel band) will be realized, must be realized by improvement steel band stripping rate and production technology.
Structure of the present invention is simple, easy construction quick, and greatly reduce construction period and construction cost, the development for Access Network provides a kind of brand-new solution; Cable core uses the sub-cable of conventional criteria φ 7.0 remote radio head, and when Base Band Unit BBU connects therebetween to wireless radio remote unit (RRU), client is without the need to purchasing non-standard fitting in addition; Restrictive coating can be peeled off from steel band more easily, and without obvious peritonaeum residual (remain and how can cause loose contact) on steel band, sheath and steel band still have certain cohesive force, can meet positive and negative 180 degree, reverse the twisting test of 10 times; Optical cable outer jacket adopts steel tygon bonding outer jacket, enhancing outside the lateral pressure resistant of optical cable, humidity resistance, also makes optical cable have mouse bite preventing performance simultaneously; Customization steel for special purposes band purchase requirement, requires that steel band overlay film peeling force is lower than industry standard 6.13N/cm, by all kinds of test and contrast, ensures that steel band stripping force value controls between 2-4N/cm the most suitable.After completing outer protecting, the cohesive force of steel band and PE protective cover material is still fine, but is divesting in sheath process, and the fracture strength of overlay film is higher than the peeling force of peritonaeum and steel band, guarantees to protect in process outside divesting, and steel band is easily peeled off without overlay film and steel band remains without overlay film.
Cable from Base Band Unit BBU to wireless radio remote unit is called wireless radio remote unit cable, this cable comprises for wireless radio remote unit (RRU) provides the optical cable of Signal transmissions to be called wireless radio remote unit (RRU) optical cable, in order to reduce Lightning Electromagnetic Fields and potential counterattack to the impact of optical cable for wireless radio remote unit, the present invention adds metal outer jacket outward at remote radio head optical cable subelement.Tower top section is directly connected with emitter by the steel band in optical cable, increases the electric conductivity of optical cable.Avoid after base station is struck by lightning, cause the damage of the communications cable.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
