2.2.6 EMI Consideration

Various interference sources, from either outside or inside the device or application system, affect the system in the
conductive ways such as capacitive coupling, inductive coupling, and electromagnetic radiation. There are two types of
electromagnetic interferences: radiated interference and conducted interference, depending on the type of the
propagation path. When the energy, often RF energy, from a component arrives at a sensitive component via the space,
the energy is known as radiated interference. The interference source can be either a part of the interfered system or a
completely electrically isolated unit. Conducted interference results from the electromagnetic wir e or signal cable
connection between the source and the sensor. Interference along the cable the interference is transmitted from one unit
to another. Conducted interference often affects the power supply of the device, but can be controlled by a filter.
Radiated interference may affect any signal path in the device, and is difficult to shield.

Effective measures should be taken for the power system to prevent electric grid interference.

The working ground of the routers should be properly separated and ke pt as far as possible from the grounding
device of the power device or the anti-lightning grounding device.

Keep the device away from high-power radio transmitter, radar transmitting station, and high-frequency large-
current device.

Measures must be taken to isolate static electricity.

2.3 Precaution for Fiber Connection

Before connecting the fibers, you should ensure that the type of optical connector and the type of fibers match the type of
the optical interface used. Moreover, you should pay attention to th e Tx and Rx directions of the fiber. The Tx end of this
device should be connected to the Rx end of the peer device, and the Rx end of this device to the Tx end of the peer
device.
