In the 21th century, high technology, which does not stand still, the world of telecommunications has went very far. The Internet has become part of every man, no man who would not know what the Internet.
Today, the Internet service providers are moving from traditional ADSL lines to technology FTTB.
What lies beneath this acronym?
FTTB (Fiber To The Building) Fiber to the building. By this expression refers to the use of an optical cable instead of copper wires. Optical cable is introduced into the apartment building, then the cable connects to the switch serving this house, from which is in turn together subscribers, but for copper cable. The optical cable can be together and the Internet, and telephony, and cable TV.
The capacity of fiber-optic cable is much greater than the capacity of copper cable, fiber optic cable also can extend over long distances without the use of amplifiers and repeaters. Unlike ADSL technology FTTB technology to handle such a load with a vengeance. Depending on the implementation of technology, speed of access to the Internet, ranging from 10 to 100 Mbits/s. The capacity of the optical channel to the switch can be from 1 to 10 Gbit/s. The technology currently uses a huge number of large Internet service providers
The qualitative difference of the technology ADSL – a symmetric channel, iespeed and the reception and transmission speed are equal, and this is a very huge plus.
Also the advantage of this technology contain the lack of need for additional equipment on the user side. The user simply connects a cable (twisted pair) into your computer and all.
What are the advantages of FTTB to ADSL?
1. Access to the arrangement at speeds up to 100 Mbit/s;
2. A break dedicated line
3. High quality data transfer
4. More opportunities for new services
5. Symmetrical bandwidth (transfer rate equals the rate of admission)
6. High noise immunity
7. Long service life – the life of fiber-optic cable is about 25 years
8. The wide bandwidth
