Abstract
An optical communications module is provided with an EMI shielding system that comprises a resistive coating disposed on one or more inner surfaces of the module housing. The resistive coating has a thickness that is greater than or equal to one skin depth and has a resistivity that is low enough to support electrical current flow, but high enough to absorb EMI radiation of a particular wavelength or wavelength range. The combination of these features causes EMI radiation to propagate in the resistive coating due to skin effect. The resistive coating absorbs at least a portion of the EMI radiation propagating therein.
