1,Common network cable: everywhere between the common network cable price is probably between 1 ~ 2 yuan a meter, especially in the university near the electronic city, the price of the general network cable is also 1 yuan a meter, the price is not very expensive, but It is worth noting that the quality of this kind of network cable are very general.
2, Category 6 Gigabit Ethernet cable: This cable is able to provide 10Gbps broadband delivery, so the quality is also very over the top, the internal use of tinned copper cores, double shielded type, to enhance the speed of the Internet, and the speed of the Internet is also more stable. The price of this Category 6 Gigabit cable is $4.5 per meter, while cat6 flat twisted pair cable costs $6 a meter per meter.
3, fiber optic cable: the price of 2 cores 2 yuan a meter, while 4 cores is estimated to be a little more than 2 yuan, 8 cores is generally 3 yuan / meter.
Expansion of knowledge: network cable crystal head connection
Network cable generally do crystal head are used T568B. In the connection of the use of network cable crystal head, T568A/T568B can only be differentiated in the wiring color. And the color order of the network cable crystal head is as follows:
T568A wiring order is: green white, green, orange white, blue, blue white, orange, brown white, brown.
The T568B is wired in the following order: orange-white, orange, green-white, blue, blue-white, green, brown-white, brown.
1. There are two ways to connect the network cable, one is parallel wiring method.
Parallel wiring method is what we call the straight wire connection, generally between the same equipment, directly using the network cable connection, both ends of the cable are TIA/EIA-568A standard or TIA/EIA-568B standard.
The other type is cross-wire connection. Crossover wire connection method is mainly between the same equipment, but also can be used to cross wire connection method, that is, one end of the TIA/EIA-568A standard, the other end of the TIA/EIA-568B standard.
2. Peer-to-peer network establishment.
If it is between two computers can also be connected with a network cable, network cable and rj45-type network cable plug between the even method, is one end according to the TIA / EIA-568A wiring sequence, one end according to the TIA / EIA-568B wiring sequence, and then the network cable through the rj45 plug inserted to connect the computer's network cable jack, which completes the two computers between the physical connection. This connection of the network cable can not be used directly, to be set up first.
3, setup program.
After connecting the two computers, you have to set the subnet mask, gateway settings, set access rights and **** enjoy. This will be two computers set up, it will form a similar LAN data *** enjoy.
