Abstract: PURPOSE: A noise cancellation device in an optical communication system is provided to cancel noise in a low frequency range by using an optical detection unit having differential output. CONSTITUTION: An optical detection unit (10) outputs differential output by converting optical signal received from an optical network unit (ONU) into an electrical signal. The differential output includes first output and second output. A low pass filter (LPF) (20) passes a signal in a specific low frequency range in the second output. A variable phase trimmer (VPT) (35) controls a phase of the first output to make a signal passed through the LPF and the first output inputted from the optical detection unit destructively interfere with each other. A coupling unit (30) couples the first output and the output of the LPF. [Reference numerals] (30) Coupling unit; (AA) Optical path; (BB) Electrical path
