Methods to Reduce Radiated Emissions From Optical Transceivers

This paper discusses downward angular installation methods to reduce radiated emission levels from transceivers so that equipment have extra margin to compensate increased radiated emission levels from certain transceivers. A theoretical calculation of transceiver placement angle for lower radiated emisssions is presented. Experimental data for different downward angular placement for a simulated transceiver and for transceivers installed in a network equipment frame is also presented and results are discussed.
