Application Notes
Application Notes
Gigabit transceivers and matching circuits are high frequency components and shall be
terminated as recommended in the application notes for proper EMI performance.
Electromagnetic emission may be caused by these components.
To prevent emissions it is recommended that cutouts for the fiber connectors be
designed as small as possible.
It is strongly recommended that the Tx plug and the Rx plug be separated with a bar that
divides the duplex SC opening.
If shielded parts are employed, they should be in proper contact with the bezel (back
plane).
Since the shield is galvanically isolated from signal ground it is strongly recommended
to prevent any contact between shield and the circuitry i.e. even any ground connection
on the pcb may be harmful to EMI performance.
In cases where EMI performance becomes critical it has proven to be helpful when using
SC-plugs with less metal parts inside (as Infineon fibers).
