The embodiment of the present invention does not limit the implementation of step 204.For example, overall gain regulated quantity can be averagely allocated to this n far-end unit to be regulated, certainly can also have other distribution methods.
For fear of because of to excessive channel quality and the poor problem of telecommunication service quality that causes this n far-end unit to be regulated of the gain-adjusted of this n far-end unit to be regulated, optionally, the gain adjustment amount of the arbitrary far-end unit to be regulated in the individual far-end unit to be regulated of described n is less than or equal to the specified maximum gain regulated quantity of this far-end unit to be regulated and the smaller value in the first numerical value; The minimum incoming level of the terminal that wherein, described the first numerical value is this far-end unit carry to be regulated and the difference of described Second Threshold.Channel quality and the telecommunication service quality that in this case, can guarantee the far-end unit to be regulated after this downward gain can meet the requirement of its coverage to channel quality and telecommunication service quality.
Optionally, after step 203, the method can also comprise that steps A is to step D:
Steps A: according to described overall gain regulated quantity, a described n specified maximum gain regulated quantity and described n minimum incoming level, determine whether described n far-end unit to be regulated can share described overall gain regulated quantity;
Step B: if described n far-end unit to be regulated shared described overall gain regulated quantity not, the minimum incoming level that obtains the terminal of institute's carry is less than described Second Threshold, be more than or equal to m far-end unit of the 3rd threshold value, as m far-end unit to be regulated simultaneously;
Step C: m specified maximum gain regulated quantity obtaining described m far-end unit to be regulated;
Step D: according to m minimum incoming level of the terminal of described overall gain regulated quantity, a described m specified maximum gain regulated quantity and described m far-end unit carry to be regulated, the gain of lowering described m far-end unit to be regulated.
It should be noted that, during specific implementation, above-mentioned steps D can be: m minimum incoming level of the terminal of m definite far-end unit carry to be regulated in the m obtaining in the difference of the gain adjustment amount that can share according to n definite in overall gain regulated quantity and step 202 far-end unit to be regulated, a step C specified maximum gain regulated quantity and step B, the gain of lowering this m far-end unit to be regulated.In this optional implementation, step 204 can above-mentioned steps A to before the arbitrary step in step D/in/carry out afterwards.
Further alternative, the grade of service of each far-end unit to be regulated in described m far-end unit to be regulated is all more than or equal to the 4th threshold value.
For fear of because of to excessive channel quality and the excessively poor problem of telecommunication service quality that causes this m far-end unit to be regulated of the gain-adjusted of this m far-end unit to be regulated, optionally, the gain adjustment amount of the arbitrary far-end unit to be regulated in the individual far-end unit to be regulated of described m is less than or equal to the specified maximum gain regulated quantity of this far-end unit to be regulated and the smaller value in second value; Wherein, described second value is the minimum incoming level of terminal and the difference of described the 3rd threshold value of this far-end unit carry to be regulated.
The method of making an uproar at the bottom of the reduction base station that the present embodiment provides, makes an uproar by lowering at the bottom of the gain of far-end unit to be regulated reduces base station.Due in optical fiber distribution system, the output noise of far-end unit can increase along with the increase of its gain, so when the lifting value of making an uproar at the bottom of base station is more than or equal to a threshold value, can be by lowering the gain of far-end unit to be regulated, the output noise of far-end unit to be regulated is reduced, and then the output noise of optical fiber distribution system is reduced, and make an uproar at the bottom of having reached reduction base station, increase the coverage of optical fiber distribution system and the object that improves the performance of optical fiber distribution system.In addition, the gain that the present embodiment is lowered far-end unit to be regulated in conjunction with the minimum incoming level of the terminal of far-end unit institute carry, when can make an uproar at the bottom of realize reducing base station, guarantees that the service quality of each terminal of far-end unit to be regulated institute carry can be too not poor.
