PURPOSE:To provide the power line communication network and the power line communication coupler for making an effective use of the power line communication by performing the power line communication between the power lines separated by the use of high frequencies by means of power transformers, etc. CONSTITUTION:A coupler 70 for power line communication connects between the 1st power line 10-1, 20-1, 30-1 separated in the high frequency by a power transformer 60 and the 2nd power line 10-2, 20-2, and 30-2 and the hues of the 1st power line and the hues of the 2nd power line in the high frequency. Thus, the power line communication between the 1st power line communication equipments 41-1, 42-1, 43-1 connected to the 1st power line and the 2nd power line communication equipments 41-2, 42-2, and 43-2 connected to the 2nd power line is enabled. |
