Gigabit Unmanaged Switch

Requirements for Cabling Indoors

When cabling indoors, keep a certain distance away from the devices that may cause high-frequency interferences, such as down-conductor cable, powerline, power transformer and electromotor.

The main cable should be paved in the metal raceway of the access shaft. When cabling, keep the loop area formed by the cable itself as small as possible.

Requirements for the distance between Ethernet cable and other pipelines are shown in the table.

The two diagrams below demonstrate parallel net length and parallel-overlapping net height.

Note: The above minimum net length/height is required when metal raceway is not used. If any requirements cannot be met, you can add a steel tube or metal raceway for shielding.

Requirements for the distance between Ethernet cable and high-power electric devices are in following tables.
