Brief description of the drawings
Describe the present invention 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
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
See figures.1.and.2, the present invention includes cable core, cable core by the painted processing of optical fiber 1 after outer cladding tight sleeve layer 2 successively, subelement stiffener 3 and subelement sheath 4 form, 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 peeling force values are controlled at steel band 8 and the steel bonding oversheath 9 of 2-4N/cm, steel bonding oversheath 9 adopts the low rate steel outer protective polyethylene cover of peeling off, the cohesive force of steel band 8 and steel bonding oversheath 9 meets positive and negative 180 degree and reverses the twisting test of 10 times.
As further improvement, many cable cores can be lined 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 therein.
The present invention utilizes existing conventional structure to zoom out light unit as less radio-frequency, both can meet the Customer Standard accessory problem that continues, and can utilize again company's existing resource to carry out production.
The present invention is wireless base station remote radio optical cable unit, and the Base Band Unit BBU that is laid in, realizes a BBU and supports multiple RRU between the two to wireless radio remote unit (RRU).Adopt BBU+RRU Multi channel.
Because optical cable need extend to tower top, and in optical cable, there is metal tape to exist, therefore be very easily struck by lightning, cause the damage of base station equipment, therefore, optical cable need to be carried out to grounding, therefore in use, tower top section is to be 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 so just causes in the time of stripping sheath, and extremely difficulty divests, and therefore needs emphasis to solve the adhesion problem between sheath and steel band for this kind of optical cable.
The present invention increases steel bonding oversheath outward at conventional less radio-frequency dragging optical cable unit cable, utilize iron and steel conductive characteristic, after peeling off, oversheath make steel band dock with the conducting end of other positions as conducting metal separately, before it enters machine room, feeder line outer jacket is done to grounding one time, most of lightning current is directly introduced to machine room earth mat, thereby reduced the thunder energy that enters machine room.But to realize fully stripped state between steel band and PE protective cover material (after being stripping outer jacket, steel band overlay film also completely band remove, only remaining base steel band), must peel off rate and production technology realizes by improving steel band.
The present invention is simple in structure, easy construction is quick, has reduced greatly construction period and construction cost, for the development of Access Network provides a kind of brand-new solution; Cable core uses conventional criteria φ 7.0 less radio-frequencies to zoom out sub-cable, and in the time that Base Band Unit BBU connects between the two to wireless radio remote unit (RRU), client is without purchasing in addition non-standard fitting; Restrictive coating can be peeled off from steel band more easily, and obviously peritonaeum residual (can cause loose contact more than residual) of nothing on steel band, and 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 the bonding outer jacket of steel tygon, having strengthened the lateral pressure resistant of optical cable, having put outside damp performance, also makes optical cable have mouse bite preventing performance simultaneously; Customization steel for special purposes band purchase requirement, requires steel band overlay film peeling force lower than industry standard 6.13N/cm, by all kinds of tests and contrast, ensures that steel band peeling force value is controlled between 2-4N/cm the most suitable.Complete after outer protecting, the cohesive force of steel band and PE protective cover material is still fine good, but divesting in sheath process, the fracture strength of overlay film will be higher than the peeling force of peritonaeum and steel band, guarantees to protect outside divesting in process, on steel band, easily peel off without overlay film and steel band on residual without overlay film.
Be called wireless radio remote unit cable from Base Band Unit BBU to the cable wireless radio remote unit, in this cable, being included as wireless radio remote unit (RRU) provides the optical cable of signal transmission to be called optical cable for wireless radio remote unit (RRU), in order to reduce the impact on optical cable for wireless radio remote unit of Lightning Electromagnetic Fields and potential counterattack, the present invention adds metal outer jacket outward at less radio-frequency dragging 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.After having avoided base station to be struck by lightning, cause the damage of the communications cable.
More than show and described 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; that in above-described embodiment and instructions, describes 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.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
