Description
Technical field
It the utility model is related to communication technical field, more particularly to a kind of photoelectricity mixing junction box, photoelectricity Hybrid connections system
System.
Background technology
Mobile base station includes baseband processing unit (Base Band Unit, BBU), electric power supply unit (Power
Supply Unit, PSU) and need to be respectively connected to the rwo Remote Radio Unit (Radio Remote Unit,
RRU).Connection between BBU, PSU and RRU includes the data link transmitted by optical fiber (optical fiber) and passes through electricity
The power link of source line transmission.
Current a solution is that direct current electric wire/optical fiber connects (referring to Fig. 1) independently of each other.In this scenario,
BBU, PSU are connected by separate power line with optical fiber, in this case, when there are many RRU a base station, are had
Very more optical fiber and cable are fixed on tower.
For simple and quick installation and saving expense, it will usually merge using by optical fiber and cable in a bellows or pipe
In set, so-called mixing cable.And it is further desired that in mixing big, for multiple RRU, with reference to optical fiber and power line
Main feeder and independent foundation connection between mixing wire jumper that is small, being only used for a RRU.
Current Hybrid connections scheme mainly has two kinds.The first Hybrid connections scheme is as shown in Fig. 2 a support is multiple
RRU non-water-tight mixing main feeder assembly, its both ends have multiple independent power supplys and optical fiber branch road respectively.Main feeder assembly
Branch terminal for power connector end and the joints of optical fibre.One RRU, mixing are supported using so-called mixing wire jumper in end
The photoelectricity branch at wire jumper both ends is less than main feeder.On mixing wire jumper, its branch terminal is power connector and the joints of optical fibre,
One main feeder is connected to multiple wire jumpers (being usually four) by the junction box of a waterproof.
The problem of solution, is to connect, it is necessary to open the photoelectricity that junction box is carried out between main feeder and wire jumper at the scene
Connect, power supply connects the connection that mistake is likely to result in work with optical fiber.

Optical fiber MPO lock pins, power input are contact pin power connectors more than one；Multiple photoelectricity mixing output connections being fixed on box
Head, it is respectively used to connect main feeder assembly and mixes wire jumper.
The first scheme is compared, and the inside connection for eliminating the power supply at most of scene, optical fiber is the advantages of the program
Work.But the program still needs one strong fan-out structure with fire resistance characteristic of additional designs, for being pointed to lead
Optical fiber and power line at the top of feeder line carry out separated time.Liang Zhong branches need also exist for more in-site installation and branch assembler
Make.It is whole so as to cause and the optical fiber of wire jumper is often bad by unfirmly closing in some regions, especially tropical area, tower top
The damage of fiber link (data link).It would therefore be desirable to have quicker, simple mount scheme, the program is required to protect
Optical fiber, expense can be saved, and can be provided between RRU and BBU and a kind of stablize strong connection.
The problem of understanding, being primarily present in existing scheme includes：There is power supply and fiber optic tap at the top of main feeder, add
The fixed work of joint connection in site operation and branch assembling inside junction box, and easily cause misconnection.Need specific strong
Strong waterproof fan-out structure, work is fixed so as to add expense and in-site installation.
