Shielded (S/FTP) PVC CM Ethernet Network Patch Cable

Ethernet cable connections;
The connection scenarios between different network layers using straight-through network cables mainly include:
Connect the switch or HUB to the router;
Computers (including servers and workstations) are connected to switches or HUBs;
The switch is connected to the switch through the uplink port;

The connection scenarios between the same network layer using crossover cables mainly include:
Computer connected to router
Switch to switch connection
Connection between HUB and HUB
The two computers are directly connected
Router Interface Connections to Other Router Interfaces

Ethernet interface of ADSL Modem and network card interface of computer
At present, most network devices have the port auto-negotiation function. After the auto-negotiation function is enabled, the local end and the peer end will automatically negotiate the communication parameters. At this time, the connection can use a straight-through network cable or a crossover network cable.

Ethernet cables consist of twisted pairs and RJ45 connectors. The RJ45 connectors have two wire sequence standards, T568A and T568B, according to the arrangement of the twisted pairs, as shown in Table 7-5.

Table 7-5 T568A and T568B cable sequence standards

Pin sequence

According to whether the wire sequence standard used at both ends of the Ethernet cable is the same, the Ethernet cable is divided into two types: straight-through network cable and crossover network cable.

Straight-through network cable: The wire sequence standards used at both ends are exactly the same, and both ends are connected according to the T568B wire sequence.

Table 7-6 lists the pin relationship of the straight-through network cable.
Table 7-6 Pin relationship of straight-through network cable

Crossover network cable: The wire sequence standards used at both ends are different. One end is connected according to the T568A wire sequence, and the other end is connected according to the T568B wire sequence.

Table 7-7 lists the pin relationship of the crossover cable.

According to the requirements of the existing network, users can choose a straight-through network cable or a crossover network cable. For the environment with strong electromagnetic interference, it is recommended that the user choose a network cable with shielding function. When the cables need to be extended, the user configures a network port connector (part number: 14080099) and an extension cable in a ratio of 1:1 according to the number of cables.
