EMI
All interference sources, either from outside or inside of the device or application system, affect the device by capacitive
coupling, inductive coupling, or electromagnetic waves.
Electromagnetic interference (EMI) occurs due to electromagnetic radiation or conduction, depending on the transmission
path.
Radiation interference occurs when energy, usually radio frequency energy, is emitted from a device and propagated
through space that disturbs other victims. The interference source can be part of disturbed system or a fully electrically
isolated unit. Conduction interference occurs when interference is transferred from one unit to another unit through cables,
which are usually electromagnetic wires or signal cables connected between the source and the victim. Conduction
interference often affects the power supply of the device, and can be eliminated by using filters. Radiation interference can
influence the path of any signal from the device, which is hard to be shielded.
Take effective measures against interference from the power grid.
Keep the AP far away from the grounding or lightning protection devices of power equipment.
Keep the AP away from high-power radio stations, radar stations, and high-frequency high-current devices.
Take electrostatic shielding measures.
Fiber Connection
Before connecting fiber cables, make sure the model of the optical transceiver and fiber type match the optical port. The
transmit port on the local device should be connected to the receive port on the peer device and vice versa.
