Preparations for building a dormitory Network: Prepare a network cable

Preparations for building a dormitory Network: network cable production is a physical activity. Introduction of some common network cable knowledge, network cable production RJ-45 line production: First prepare the tools we need: Pressure clamp.

◆ Preparations for establishing a dormitory Network: First extract a short line and then peel off the outer skin (the length is about 1.2-1.3 cm );

◆ Reverse winding of twisted pair wires based on Cabling Standards. The current wiring standards include t568a and t568B. Generally, t568B standards are used. There is no difference between the two standards in nature, but the sorting order of the lines is just different. The sequence of the T568B standard from 1 to 8 is: Orange, orange, green, white, blue, blue, white, green, brown white, brown. T568A is based on T568B. You can change the sequence of 1 <--> 3, 2 <--> 6 to each other.

◆ Preparations for establishing a dormitory Network: Use a crimping tool to cut uneven headers;

◆ Insert the wire into the crystal head and clamp it with a crimping clamp (strong). The other end is also connected according to the same standard. Here, the author reminds readers that when using the HUB, switch, and other collection line equipment, these two standards cannot be mixed. When the dual-host interconnection does not use a hub, the T568A standard must be adopted first, and the T568B standard must be used on the other. According to regulations, the ports 1 and 2 of the network adapter send data, while the ports 3 and 6 are the receiving data pins. 1, 3, 2, 6 line swap is mainly to enable one network card 1, 2 feet to send data, the other network card is easy to use 3, 6 feet to receive.

◆ Preparations for establishing a dormitory Network: Use a tester to test whether your network is connected or whether the data can be connected through the network.

Preparations for building a dormitory Network: creating a fine cable: when creating a network with a fine cable, the distance between computers is long and short, so the proper length of the network cable is required. First, prepare your weapons: sharp mouth pliers, diagonal pliers, wrenches, and multimeter.

◆ First, place the annular screws, metal rings, and photo and skin washers in the locking BNC connector assembly on the end of the RG58 A/U cable in sequence;

◆ Remove A small section of RG58 A/U coaxial cable outer package (about 1-1.2), expose some of the Guide power grids, and unplug the guidance power grids;

◆ Remove a small Insulator with excellent core wires and expose the center conductor. The length of the center conductor shall be directed to the tip of the needle for which the needle is difficult to gold-plated, and too many bare wires shall not be exposed at the rear.

◆ Preparations for building a dormitory Network: put a metal cone.

◆ Insert the bare wire part of the center conductor into the rear half of the silver-plated needle. After insertion, the needle can be slightly rotated in a proper direction and cannot exceed two circles;

◆ Insert the gold-plated needle into the metal casing, and push the rubber washer to the direction of the joint, so that the open guide grid can withstand the front-end metal cone.

◆ Sort the power guide in the joint, push the metal gasket into it, cover the power guide completely, push the ring screw to the direction of the metal casing, and tighten the ring screw.

◆ Preparations for building a dormitory Network: production is complete. You can test whether your network cable can be connected.
