What Is The Difference Between Fiber Broadband And Ordinary Broadband?
Nowadays, the network has become an indispensable part of people’s lives. With the continuous innovation of technology, the medium used to spread network signals has changed from ordinary broadband at the beginning to the fiber-optic broadband that we often hear about, then fiber-optic broadband and ordinary broadband What is the difference?
Optical fiber transmits signals in the form of light pulses, and uses glass or plexiglass as the network transmission medium. It is a transmission medium, such as twisted pair, thick cable, thin cable, etc. Its transmission speed is much faster than ordinary medium, which can reach more than gigabit per second. For example, the general speed of optical fiber can reach 100M. Copper wire is hard to reach.
The advantage of fiber optic broadband lies in the low cost of networking equipment such as hubs and Ethernet switches. Users do not need to install ADSL modems. This is the capital for Ethernet and ADSL competition. Optical fiber broadband users have less investment and lower cost prices. The ADSL access of ordinary broadband applications uses the existing local telephone network and the computer room of the telephone exchange. It cannot be separated from the fixed telephone and is subject to geographical restrictions. At the same time, the telephone fee also increases the product cost.
ADSL has general requirements for line quality. When the line quality is not good, stability will be affected. When the transmission rate is higher, the influence of attenuation and crosstalk on the signal is greater, and sometimes the network rate drops and disconnects.The fiber-optic broadband access uses a different network from the telephone network. The corridor switch and the community center switch, the community center switch and the central office switch are connected by optical fiber. The network has high stability and reliability, not to mention the mutual influence. problem.
The advent of the optical network era is not only the increase in Internet access speed brought about by optical fiber access, but more importantly, various information applications based on optical fiber networks. In response to the implementation of the national "Broadband China" strategy, the current Provinces have also successively launched plans for "all optical network cities". In early 2011, China Telecom took the lead in launching the "Broadband China·Optical Network City" project. The ultimate goal is to enable users to achieve the demand for "high-speed Internet access anytime, anywhere". Let life truly achieve the "speed of light" development.
