Abstract
An optical transceiver module is provided that has an EMI absorbing assembly that comprises an EMI absorbing device that is electrically grounded rather than standing in free space in the transceiver module so that the assembly absorbs both the magnetic and electrical components of the EMI. In accordance with an embodiment, the EMI absorbing assembly includes a leadframe about which an EMI absorbing material is cast. The leadframe preferably is shaped in a way that prevents or lessens the occurrence of resonant EMI modes in the transceiver module housing.
