Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, in order to make the reader understand this application better, many technical details are proposed.But even if without these skills
Art details and various changes and modifications based on the following respective embodiments can also realize that each claim of the application is required and protect
The technical solution of shield.
One preferred embodiment of the utility model is related to a kind of far-end RF module arranging device.As shown in Fig. 2, distal end
Radio-frequency module arranging device includes：Optical fiber distribution box 21, far-end RF module RRU 22, antenna 23 and feeder line 24.RRU 22
It is connected by feeder line 24 with antenna 23.When being connected together RRU 22 with antenna 23 by feeder line 24, RRU22 is arrived in principle
The routing of feeder line 24 of antenna 23 is no more than 50 meters, if the feeder line 24 of RRU 22 to antenna 23 is route more than 50 meters, needs to do
Loss balancing designs.RRU 22 is fixed on the lateral surface of optical fiber distribution box 21.Wherein, the optical fiber link of RRU 22 joins for optical fiber
Apllied optical fiber link in case 21, is such as connected to the optical port of optical fiber distribution box 21 by the optical port of RRU 22.By by RRU 22
It is fixed on the lateral surface of optical fiber distribution box 21 so that be fixed on the placement spirit of the RRU 22 of 21 lateral surface of optical fiber distribution box
It is living, it is small without 22 independent cloth of RRU is placed on the big house of the intensive inner city of building top, data service, the density of population
Area etc..Such as, can be, but not limited to by by optical fiber distribution box 21 on fire hydrant by by RRU 22 be mounted on fire hydrant, this
When, antenna 23 can be fixed on fire hydrant, antenna 23 can also be fixed on to neighbouring pole, light pole, electric pole etc..
Can be to avoid RRU 22 to be laid to signal coverage rate that is too high, therefore can greatling improve mobile radio communication, and save big
The property cost of amount is paid.Since the optical fiber link of RRU 22 is apllied optical fiber link in optical fiber distribution box 21, so energy
Apllied optical fiber link in optical fiber distribution box 21 is enough made full use of, the Installed capital cost of optical fiber link is reduced.
Far-end RF module arranging device can also include the power supply for providing voltage for RRU 22；Power electric connection in
The feeder ear of RRU22；The value of voltage is preferably 48V.Wherein, power supply can be the power supply in far-end RF module arranging device,
It may be external power supply.When power supply is the power supply in far-end RF module arranging device, power supply can be placed on optical fiber friendship
It connects in case 21.When power supply is external power supply, far-end RF module arranging device can also include AC/DC convertor；Alternating current-direct current
Converter is electrically connected between power supply and the feeder ear of RRU 22.For example, neighbouring light pole may be used in external power supply
Power supply.Directly external power supply can be utilized to power for RRU 22 by this design, far-end RF module can be saved and lay dress
The cost set.
During actually laying 22 base stations RRU, the external pole of installation can be set near optical fiber distribution box 21
25, and antenna 23 is fixed on external pole 25.By antenna 23 is fixed on external pole 25 can make RRU 22 and
The placement of antenna 23 is more flexible.Under normal conditions, be mounted on external pole 25 on antenna 23 can at least two,
Concrete numerical value is determines according to actual conditions.
Preferably, 25 joint grounding of RRU 22, optical fiber distribution box 21 and external pole so that 22 Hes of RRU can be protected
Optical fiber distribution box 21.In actual design, each component or each equipment in far-end RF module arranging device need equipotential
Connection.And in order to avoid thunder and lightning punctures, it is also necessary to the synthetical prevention and cont rol of atmospheric over voltage protection and direct lightning strike protection is designed,
To protect far-end RF module arranging device.
It should be noted that it is former to follow following addressing safety when laying the RRU 22 being fixed on optical fiber distribution box 21
Then：
Answer addressing landform it is flat, it is smooth and around without hindrance block material, base altitude higher than require highest water level on records
0.5 meter or more of the good section of geology, does not answer addressing in the area easily basined irrigation by ponding.Addressing should not be selected inflammable and explosive
Near warehouse, factory, enterprise, material stockyard etc., it should not also select to distribute more dust or the row of being corrosive in process of production
It puts near the factory and enterprise of object.Addressing should not be close to high-voltage line, gas station, high-power wireless transmitting station, Highpower Radar Post, height
Piezoelectricity station etc. influences the environment of mobile communication.Addressing must satisfy the requirements such as communication security secrecy, people's air defense, fire-fighting.
Through the above, it is not difficult to find that present embodiment makes the RRU 22 for being fixed on 21 lateral surface of optical fiber distribution box
Placement it is flexible, it is close without 22 independent cloth of RRU is placed on the intensive inner city of building top, data service, population
Big residential quarters etc. are spent, the signal coverage rate of mobile radio communication can be greatlyd improve, and save a large amount of property fees
With expenditure, the Installed capital cost of optical fiber link can also be reduced.
It will be understood by those skilled in the art that the respective embodiments described above are to realize the specific implementation of the utility model
Example, and in practical applications, can to it, various changes can be made in the form and details, without departing from the spirit of the utility model
