To calculate estimated load currents

• Add Watts required for ONT and each POE device that will be connected to the ONT​
• Divide the total Watts by the Input Voltage

​

Example:  ONT = 12W
                                      Access Point = 8W
                                      IP Phone = 8W
                                      Total 28W
                 
                                      28W / 56VDC =  .5 Amps
                            

Maximum Cable Distance will be determined by the nominal voltage required for ONT operation.
Check manufacturer specifications for this value.
