Abstract:
1. An electromagnetic interference (EMI) collar for use with an optical transceiver module, the EMI collar comprising: a band having an inner surface and an outer surface, wherein the EMI collar is configured to be secured to a housing of the optical transceiver module by securing the band to the housing such that the inner surface of the band is in contact with an outer surface of the housing, the band comprising an electrically conductive material; and a plurality of spring fingers, the spring fingers comprising an electrically conductive material, each spring finger having a proximal end that is connected to the band and a distal end that extends away from the band, each spring finger having at least one respective dimple formed therein between the proximal and distal ends of the respective spring finger, wherein each dimple is an indentation in an outer surface of the spring finger that creates at least two additional electrically conductive contact points, said at least two additional electrically conductive contact points being located at first and second ends of the respective dimple formed on the respective spring finger.
