Fiber optic broadband has several access methods

Hello, broadband access is divided into ADSL, LAN, FTTH, PON four:

1, ADSL: Chinese name: for asymmetric digital subscriber line loop . It uses the existing pair of copper twisted-pair wires to provide users with upstream and downstream asymmetric transmission rate, upstream for low-speed transmission; downstream for high-speed transmission. Applicable to ordinary home users, small and medium-sized business users with broadband service needs;

2, LAN: access mode mainly using Ethernet technology, to serve the user in the way of information technology cell. In the core node using high-speed routers, to provide users with FTTX + LAN broadband access. Basic to do a gigabit to the community, 100 megabytes to the residential building, ten megabytes to the user;

3, PON: is an emerging broadband access, can provide customers with more stable access and higher speed bandwidth;

4, FTTH: access is to maintain the user's existing communications services on the basis of the direct fiber optic lines into the user's home, replacing the original cable lines. Communication capacity and quality has been greatly enhanced, broadband can be realized 2M/4M/10M to 100M a variety of high-speed rate access, faster Internet access, network quality is more stable, online high-definition video, Internet TV, high-speed downloads, large-scale online games and other network applications more powerful.
