CHAPTER 5

5.Suggestions to Ethernet Cabling

To lessen the possibility of equipment damage and performance deduction due to electromagnetic wave and lightning interference, the following recommendations are offered for 100 Mbps Ethernet port cabling in actual engineering:

5.1. Requirements for Cable Types

Cables for 100 Mbps Ethernet port connection must be Category-5 or Enhanced Category-5 cables. On the surface of the twisted pair, you can often find some symbols like “ 24AWG CAT5”. “CAT5” represents Category-5 twisted pairs and “CAT5E” represents Enhanced Category-5 twisted pairs.

5.2. Requirements for Cabling Length

Length of 100 Mbps Ethernet cabling cannot exceed 100 meters, that is to say, the cable length from a device to a networking device or subscriber’s PC must be not more than 100 meters, as shown in the figure below. Cabling length of more than 100 meters influences effective transmission of data.

5.3. Spacing Requirements for Indoor Cabling

To keep effective data transmission and lessen interference of coupling high-frequency electromagnetic wave and lightning, it is recommended that in indoor cabling, Ethernet cables should keep an appropriate spacing from other pipelines and nearby electric equipments such as electromotor and transformer that may cause high- frequency electromagnetic interference. For the spacing requirements for indoor cabling, see 0 and 0.
