Abstract
Various embodiments of a method and device for dark current cancellation for optical power monitoring in optical transceivers are presented. In one aspect, a device includes a photosensitive module and a processing module coupled to the photosensitive module. The photosensitive module is configured to detect an optical signal and generate a first signal responsive to detecting the optical signal. The processing module is configured to determine a value of a second signal that is related to noise and determine a value of a third signal that is related to a difference between a value of the first signal and the value of the second signal.
