RG-IS2700G Series Switch Hardware Installation and Reference Guide
There are two types of electromagnetic interferences: radiated interference and conducted interference, depending on the
type of the transmission 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 wire or signal cable connection between
the source and the sensitive component, along which cable the interference conducts from one unit to another. Conducted
interference often affects the power supply of the equipment, but can be controlled by a filter. Radiated interference may
affect any signal path in the equipment and is difficult to shield.
Effective measures should be taken for the power system to prevent the interference from the electric grid.
The working ground of the switch should be preferably separated and kept as far as possible from the grounding
device of the power equipment or the anti-lightning grounding device.
Keep the equipment away from high-power radio transmitter, radar transmitting station, and high-frequency
large-current device.
Measures must be taken to shield static electricity.
2.6 Precaution for Fiber Connections
Before you connect the fibers, check that the optical connector type and fiber type match the optical interface type used. In
addition, pay attention to the Tx and Rx directions of the two-fiber bidirectional optical module. The Tx end of this
equipment should be connected to the Rx end of the peer equipment, and the Rx end of this equipment to the Tx end of
the peer equipment. The BIDI optical module needs only one-fiber, and uses different wavelengths for bidirectional
transmission. Therefore, BIDI modules need to be used in pairs. See Table B-3 in Appendix B for details.
