Avago Technologies designed HFCT-59L1ATLZ provide good performance. performance chassis dependent physical design features which help improve suppression. Avago Technologies encourages using standard suppression practices avoiding poorly EMI-sealed enclosures. Avago Technologies's transceivers (HFCT59L1ATLZ) have nose shields which provide convenient chassis connection nose transceiver.
