Abstract
Embodiments of the disclosure pertain to an optical transmitter and/or receiver comprising an electrical signal generator configured to generate an electrical signal that is unshielded or unshieldable at a predetermined frequency, a filter downstream from the electrical signal generator configured to reduce an amplitude of electromagnetic interference (EMI) at the predetermined frequency below a predetermined maximum value, an interface through which the EMI can pass in the absence of the filter, and an optical component configured to receive the electrical signal or provide an input signal to the electrical signal generator. A method of reducing EMI in an optical transmitter and/or receiver using the electrical signal generator, the filter and the optical component is also disclosed.
