PURPOSE: A time division multiple passive optical network, a method for compensating a route difference, and a recording medium storing a program executing the method are provided to delay an uplink signal as much as a distance difference by using a route in an optical line terminal. CONSTITUTION: A distance compensating unit(100) measures the route distance between a COT(Central Office Terminal) and an RT(Remote Terminal). The distance compensating unit transmits a distance difference value by using a route to an OLT(Optical Line Terminal)(200). The OLT converts the distance difference value into a time delay value. The OLT updates equalization delay information. An ONT(Optical Network Terminal)(300) controls the transmission timing of an uplink signal by the updated equalization delay information. |
