Detailed introduction of 4-core telephone line:
The telephone line is not the same as the network cable. The network cable cannot be replaced by a telephone line, because it needs 8 cores, and the telephone line is four-core or two-core, and the transmission bandwidth is not enough, but the network cable can be used as a telephone line; in addition, both The transmission signal and the technology used are different. The details are as follows:
1. The telephone line is parallel, and the network cable is generally twisted pair. The telephone line is generally two-core, 4-core or 6-core, and the network cable is generally 8-core. Telephone lines are generally used to transmit analog signals. Because the frequency is low, network cables are generally used to transmit digital signals. Because the frequency is relatively high, twisted-pair lines are used and the distance cannot be too far; so the former can be replaced by the latter, and vice versa;
2. The two are also different in terms of transmission and working principles. Telephone lines transmit analog signals, while network cables are used to connect computers and cats to transmit digital signals; while the current fiber to the home transmits network optical signals through optical fibers. The optical signal can be recognized by the network card and router only when the optical signal is converted into an electrical signal by the optical modem;
3. Telephone line Internet access is also called ADSL broadband, which uses ADSL technology to provide asymmetrical upstream and downstream bandwidth, so it is called asymmetric digital subscriber line. The telephone line uses ADSL to modulate the computer’s digital signal into an analog line number to transmit through the telephone line. After reaching the telecom side, the analog signal is demodulated into a digital signal. This way of surfing the Internet can provide both voice and data. Business.
